7 Things to Know About Hair Health
1. Hair Structure And Growth Cycle For Hair Health
Hair grows in cycles and has a basic structure that affects its strength and growth rate.
Each hair strand has a root under the skin and a shaft above; the root surrounds the hair follicle, a small pocket of skin cells.
The hair growth cycle has three phases: anagen (active growth), catagen (transition), and telogen (resting); most hair is in anagen, which lasts 2–7 years.
On average, hair grows about half an inch (1.25 cm) per month, but genetics and health can speed up or slow down this rate.
2. Proper Nutrition For Hair Health
Eating the right foods gives your hair the building blocks for strong, shiny strands.
Protein makes keratin, the main protein in hair; good sources include eggs, beans, and lean meat.
Iron and zinc help transport oxygen and repair hair cells; you can find them in spinach, lentils, and nuts.
Vitamins A and D support scalp oil balance and hair follicle health; get them from carrots, sweet potatoes, and sunlight or fortified foods.
3. Consistent Scalp Cleansing For Hair Health
Keeping your scalp clean removes extra oil and buildup that can block hair growth.
Shampoo 2–3 times per week to balance oil removal and scalp moisture.
Choose gentle surfactants (mild cleaning agents) like sodium cocoyl isethionate instead of harsh sulfates, which can dry out hair.
Rinse thoroughly to clear shampoo and conditioner; leftover residue can clog follicles and cause itchiness.
4. Adequate Hydration For Hair Health
Both drinking water and using moisturizing treatments help hair stay flexible and resist breakage.
Drink at least 8 cups (2 liters) of water daily to support overall body hydration, which keeps hair cells healthy.
Use conditioners and leave-in treatments with humectants (ingredients that draw in and hold moisture), such as glycerin or panthenol.
Limit heat styling tools (like blow dryers or flat irons) or use a heat protectant to prevent moisture loss and dryness.
5. Gentle Hair Care Practices For Hair Health
Treat your hair softly to avoid damage and split ends.
Use a wide-tooth comb on wet hair to detangle; this reduces pulling and hair breakage.
Avoid tight hairstyles (like tight ponytails or braids) that create tension and can cause hair to snap or pull out.
Pat hair dry with a soft towel or cotton T-shirt instead of rubbing, which can roughen the hair cuticle and cause frizz.
6. Regular Trimming For Hair Health
Cutting off split ends keeps hair looking neat and prevents breakage from traveling up the strand.
Split ends are frayed tips of the hair shaft that can split further up the strand if not removed.
Trim hair every 8–12 weeks to remove split ends and maintain even length.
Trim just ¼ inch (0.6 cm) for maintenance or more for growing out, using sharp scissors for a clean cut.
7. Sun Protection For Hair Health
Shield hair from sun damage to maintain strength and color.
UV rays can break down keratin (the protein in hair), causing dryness, brittleness, and color fading.
Wear hats or scarves to protect hair and scalp when spending time outdoors.
Use hair products with UV filters or natural oils (like coconut oil) to add an extra layer of sun defense.
Understanding Hair Health
Hair health depends on follicle nourishment and scalp circulation; those facing thinning, brittleness or environmental damage secure fuller, stronger strands by ensuring adequate protein, iron and B-vitamin intake and minimizing heat styling, instead of splurging on exotic topicals with scant proof of efficacy.
Why Do People Have Gray Hair?
Gray hair results from a natural decline in melanin production—the pigment responsible for hair color. Melanin is produced by melanocytes located within the hair follicle. Over time, these cells become less active or die off, leading to colorless (gray or white) hair strands.
Aging: The most common cause. Melanocyte function declines with age, typically starting in the 30s for most people, though timing varies by genetics and ethnicity.
Genetics: Genes largely determine when graying begins. If your parents grayed early, you're more likely to do the same regardless of lifestyle.
Oxidative Stress: Accumulated cellular stress and free radicals can damage melanocytes, accelerating pigment loss. This is influenced by aging, pollution, UV exposure, and internal stressors.
Nutrient Deficiencies: Low levels of vitamin B12, copper, or iron can contribute to premature graying by impairing pigment synthesis or melanocyte health.
Autoimmune Conditions: In disorders like vitiligo or alopecia areata, the immune system may attack pigment-producing cells, leading to depigmented or white hairs.
Smoking: Strongly associated with earlier graying, possibly due to increased oxidative damage and reduced scalp circulation.
Stress (Possibly): High psychological stress has been linked in some studies to faster graying, possibly through effects on stem cell depletion in follicles, though evidence is still emerging.
Gray hair is not a sign of poor health in most cases, but premature graying (before age 20 in Caucasians, 25 in Asians, or 30 in Africans) may indicate underlying issues worth evaluating.
Gray hair occurs when pigment-producing cells in hair follicles decline due to aging, genetics, oxidative stress, or nutritional deficiencies, leading to reduced melanin in hair strands.
What Causes Hair Loss?
Hair loss can occur for many reasons, ranging from genetic and hormonal factors to nutritional deficiencies and medical conditions. Understanding the type and cause of hair loss is key to finding the right treatment or solution.
Genetic Factors: The most common cause is androgenic alopecia (male and female pattern baldness), where inherited sensitivity to dihydrotestosterone (DHT) causes progressive follicle miniaturization.
Hormonal Changes: Pregnancy, postpartum, menopause, thyroid disorders, or PCOS can disrupt the normal hair cycle and lead to excessive shedding or thinning.
Stress: Physical or emotional stress can trigger telogen effluvium, a condition where many hairs prematurely enter the shedding phase. Hair loss usually appears 2–3 months after the trigger.
Nutritional Deficiencies: Inadequate intake of iron, zinc, protein, vitamin D, or B12 impairs hair follicle function and leads to increased shedding or thinning.
Medications: Drugs such as chemotherapy, beta-blockers, antidepressants, anticoagulants, and isotretinoin may cause hair loss as a side effect.
Autoimmune Diseases: In alopecia areata, the immune system attacks hair follicles, causing sudden, patchy loss. Other conditions like lupus can also involve hair loss.
Scalp Conditions: Fungal infections, psoriasis, or seborrheic dermatitis can damage follicles or obstruct growth through inflammation or scaling.
Traction and Styling Damage: Tight hairstyles, heat styling, harsh chemicals, or repeated tension on hair shafts can lead to traction alopecia or breakage.
Aging: Natural aging reduces hair follicle activity, leading to slower growth, thinning, and loss of hair density.
Toxic Exposure or Illness: Exposure to heavy metals, rapid weight loss, severe infection, or surgery can disrupt the hair cycle.
Hair loss is often multifactorial. Identifying the root cause is crucial for stopping progression and promoting regrowth when possible.
Hair loss is caused by genetics, hormones, stress, nutritional deficiencies, illness, medications, autoimmune disorders, or physical damage to hair or scalp.
What Can Impact Your Hair Health?
Hair health is influenced by a mix of internal and external factors, which impact hair growth, strength, thickness, texture, and shedding. These changes may be temporary or long-lasting, depending on the underlying cause.
Hormonal Changes: Shifts in hormones due to puberty, pregnancy, menopause, thyroid disorders, or conditions like polycystic ovary syndrome (PCOS) can disrupt the hair growth cycle, leading to thinning or excess shedding.
Nutritional Deficiencies: Low levels of iron, zinc, biotin, protein, omega-3 fatty acids, or vitamin D directly impair hair follicle function and hair shaft strength.
Stress: Physical or emotional stress can trigger telogen effluvium, where a large number of hairs enter the resting phase and fall out weeks later.
Genetics: Genetic predisposition plays a key role, particularly in androgenic alopecia (male and female pattern hair loss).
Medications and Treatments: Chemotherapy, beta-blockers, antidepressants, and other drugs may cause temporary or long-term hair loss as a side effect.
Scalp Health: Dandruff, seborrheic dermatitis, psoriasis, or fungal infections impair the environment that supports healthy follicles.
Aging: Hair naturally becomes thinner, drier, and grows slower with age due to reduced follicular activity and hormone levels.
Hair Practices: Over-washing, excessive heat styling, chemical treatments (bleaching, perming), tight hairstyles, and poor-quality hair products cause physical damage to the hair shaft and follicles.
Environmental Exposure: UV radiation, pollution, and hard water degrade hair proteins and strip natural oils, making hair brittle and dull.
Medical Conditions: Autoimmune diseases like alopecia areata, lupus, and chronic illnesses like diabetes or anemia can all negatively impact hair health.
Changes in hair health typically result from a combination of these factors, and addressing them often requires identifying the root cause or causes.
Hair health changes due to a mix of hormones, nutrition, stress, genetics, aging, scalp conditions, medications, styling damage, and environmental exposure.
How Is Hair Health Assessed?
Hair health is assessed through a combination of visual inspection, physical tests, patient history, and sometimes lab testing. These approaches help determine the condition of both the hair shaft and the scalp, and uncover potential underlying causes of hair issues.
Visual and Tactile Inspection: A clinician examines hair for signs of thinning, breakage, dullness, split ends, uneven growth, and scalp conditions (e.g., flaking, redness, inflammation).
Pull Test: Several strands are gently pulled to check for abnormal shedding. Losing more than a few hairs per tug may indicate active hair loss.
Tug or Stretch Test: This checks hair elasticity and strength. Weak or brittle strands that snap easily suggest structural damage or protein loss.
Trichoscopy (Scalp Dermoscopy): A magnified, light-assisted examination of the scalp and hair follicles helps identify miniaturization, inflammation, or abnormal follicular patterns.
Wash Test: After not washing hair for a set number of days, collected shed hairs are counted to quantify hair loss.
Trichogram or Phototrichogram: These involve microscopic examination or digital imaging of plucked hair roots to evaluate growth phase distribution and follicle density.
Blood Tests: When systemic issues are suspected, lab tests may check for iron levels, thyroid function, vitamin D, zinc, hormonal imbalances, or autoimmune markers.
History and Lifestyle Review: Assessment includes questions about diet, stress, medications, hair care routines, and family history of hair disorders.
This multi-layered assessment helps distinguish between normal variation, cosmetic damage, and medical hair disorders, guiding effective treatment plans.
Hair health is assessed through visual inspection, mechanical tests, scalp imaging, lab tests, and lifestyle review to detect damage, shedding patterns, or underlying medical causes.
What People Often Get Wrong About Hair Health?
Many common beliefs about hair health are based on myths, marketing claims, or superficial understanding. These misconceptions can lead to poor hair care choices or prevent people from addressing underlying issues effectively.
Myth: Hair Health Reflects Shampoo or Product Use Alone: Many think using premium shampoos or serums ensures healthy hair. In reality, internal factors like nutrition, hormones, and stress play a much larger role than topical products.
Myth: Hair Can Be "Repaired": Hair is dead tissue once it emerges from the scalp. It cannot truly be healed—only temporarily smoothed or protected from further damage.
Myth: Frequent Washing Causes Hair Loss: Washing does not increase hair loss. It only reveals hairs that were already in the shedding phase. However, harsh shampoos or overwashing can damage the scalp or hair shaft.
Myth: Cutting Hair Makes It Grow Faster: Hair grows from the follicle, not the ends. Trimming prevents split ends and breakage but has no effect on the actual rate of growth.
Myth: Hair Loss Is Always Genetic: While genetics play a role in pattern baldness, many types of hair loss are due to reversible causes like nutrient deficiencies, thyroid disorders, or stress.
Myth: Natural Oils and DIY Treatments Are Always Safe: Some home remedies (e.g., lemon juice, baking soda) can disrupt scalp pH, damage hair cuticles, or cause irritation.
Myth: Gray Hair Means Unhealthy Hair: Hair turns gray due to melanin loss, not poor health. Gray hair may be drier or coarser but isn’t necessarily damaged.
Understanding the science behind hair biology helps people focus on meaningful strategies—like balanced nutrition, gentle care, and medical evaluation when needed—instead of relying on cosmetic fixes or myths.
People often wrongly believe that external products fix hair health, that hair can be repaired, or that hair loss is always genetic—when in reality, internal health and proper care matter most.
Why You Should Optimize Your Hair Health?
Optimizing hair health brings benefits beyond appearance—it also supports emotional well-being, reflects internal health, and improves hair performance under stress or aging.
Improved Appearance: Healthy hair looks shinier, fuller, and more vibrant. It enhances self-image and contributes to overall aesthetic appeal.
Increased Hair Strength and Resilience: Well-nourished hair is more resistant to breakage, environmental damage, and styling stress. This preserves length and thickness over time.
Better Scalp Health: A healthy scalp reduces flaking, irritation, or itching, supporting long-term follicle activity and stable hair growth.
Delayed Hair Aging: Good hair care and nutrition help maintain hair pigment longer, reduce dryness, and slow down miniaturization or thinning associated with aging.
Emotional and Psychological Boost: Thick, healthy hair can improve confidence, social comfort, and mental health, especially for those recovering from hair loss.
Early Indicator of Systemic Health: Optimizing hair often involves addressing deeper issues like iron deficiency, thyroid dysfunction, or chronic inflammation—improving general health.
Reduced Need for Aggressive Styling or Treatments: Healthier hair needs less cosmetic correction (e.g., straightening, coloring), which further prevents cumulative damage.
Overall, prioritizing hair health is both a cosmetic and wellness strategy, with ripple effects on quality of life and systemic health awareness.
Optimizing hair health improves appearance, boosts strength, supports scalp condition, slows aging, enhances confidence, and reflects broader internal health.
What Are Key Hair Health Metrics to Track?
Tracking specific hair health metrics helps evaluate progress, detect early issues, and personalize interventions. These metrics reflect both the condition of the hair itself and the function of the scalp and follicles.
Hair Density: Refers to the number of hair strands per square centimeter on the scalp. Lower density may signal hair thinning or follicle miniaturization.
Hair Shedding Rate: Normal shedding is about 50–100 hairs per day. A consistent increase indicates stress, hormonal changes, or nutritional issues.
Hair Growth Rate: Healthy hair grows about 1–1.5 cm per month. Slower growth can suggest nutrient deficiencies, hormonal imbalance, or aging.
Hair Shaft Thickness: Thicker strands are generally stronger and healthier. Miniaturization (thinner hairs) is a hallmark of pattern hair loss.
Scalp Condition: Signs of inflammation, redness, flaking, or oil imbalance affect follicle health and hair quality.
Elasticity and Breakage: Strong, elastic hair resists snapping when gently stretched. Excess breakage suggests protein or moisture deficiency.
Shine and Texture: Shine reflects cuticle health and oil balance. Dullness, coarseness, or roughness indicate environmental or chemical damage.
Hair Color Integrity: Premature graying or fading may reflect oxidative stress or deficiencies in vitamins like B12 and copper.
Photographic Tracking: Regular photos of hairline, parting, or crown under consistent lighting help monitor visual progress over time.
Monitoring these parameters regularly, ideally with professional input, helps maintain optimal hair condition and detect problems before they become severe.
Key hair health metrics include density, shedding rate, growth speed, strand thickness, scalp condition, breakage levels, shine, and elasticity—all vital for detecting changes early.
How Does Your Lifestyle Shape Hair Health?
Lifestyle habits have a major impact on hair health by influencing nutrient availability, hormonal balance, inflammation, and physical stress on hair and scalp. Positive lifestyle choices support stronger, healthier hair, while negative ones contribute to hair loss, dullness, and breakage.
Diet: A nutrient-rich diet supports follicle health. Deficiencies in protein, iron, zinc, biotin, omega-3s, or vitamin D directly weaken hair and impair growth. Crash diets and low-calorie plans often trigger temporary hair shedding.
Stress Levels: Chronic stress disrupts the hair cycle and increases cortisol levels, which can trigger telogen effluvium (excessive shedding). It may also worsen scalp inflammation or autoimmune hair loss.
Sleep Quality: Poor sleep impairs tissue repair, hormonal regulation, and stress control—all essential for healthy hair growth. Nighttime repair processes also affect scalp and follicle renewal.
Physical Activity: Regular exercise boosts circulation and nutrient delivery to the scalp, supporting follicle function. It also helps regulate hormones and reduce chronic stress.
Hair Care Habits: Frequent use of heat tools, chemical treatments, and tight hairstyles can physically damage hair strands and stress follicles, leading to breakage or traction alopecia.
Hydration and Alcohol Use: Dehydration and excessive alcohol intake can dry out hair and scalp, reduce nutrient absorption, and impair overall skin and hair condition.
Smoking: Smoking reduces blood flow to the scalp, damages follicular DNA, and increases oxidative stress—all linked to premature graying and hair thinning.
Sun and Pollution Exposure: Unprotected UV exposure and air pollutants degrade hair proteins, dry out strands, and irritate the scalp.
In short, healthy hair is an external reflection of internal balance and consistent self-care. Lifestyle improvements can prevent or reverse many common hair problems.
Lifestyle choices—especially diet, stress, sleep, exercise, and hair care habits—strongly influence hair health by affecting follicle function, nutrient supply, and physical damage.
How Does Nutrition Impact Hair Health?
Nutrition directly affects the health, growth, and strength of hair by supplying essential building blocks and regulating the biological processes that support hair follicles. A poor diet can lead to dullness, thinning, increased shedding, and even hair loss.
Protein: Hair is made primarily of keratin, a protein. Inadequate protein intake slows hair growth and weakens hair shafts, increasing breakage and shedding.
Iron: Iron is vital for oxygen transport to hair follicles. Low ferritin (iron storage) levels are strongly associated with diffuse hair shedding, especially in women.
Zinc: Zinc supports tissue repair and immune balance at the follicle. Deficiency can cause hair loss and a dry, flaky scalp.
Vitamin D: Helps regulate hair follicle cycling and immune responses. Low levels are linked to autoimmune hair loss and chronic shedding.
B Vitamins (especially Biotin, B12, Folate): Support red blood cell production and cellular energy, both critical for follicle activity. Biotin also helps with keratin production.
Omega-3 Fatty Acids: Reduce scalp inflammation, promote hydration, and support healthy hair structure. Found in fatty fish, flaxseeds, and walnuts.
Antioxidants (Vitamins A, C, and E): Protect follicles from oxidative stress. Vitamin C also helps with collagen synthesis and iron absorption.
Water and Hydration: Adequate fluid intake keeps hair hydrated and maintains scalp elasticity and barrier function.
Caloric Balance: Severe caloric restriction or crash dieting can shift hair into the resting (telogen) phase, triggering temporary hair loss (telogen effluvium).
Balanced, nutrient-dense diets rich in whole foods are key to maintaining optimal hair health. Even minor deficiencies can impair hair quality long before other symptoms appear.
Nutrition impacts hair health by supplying key nutrients like protein, iron, B vitamins, zinc, and omega-3s that support follicle function, structure, and growth—deficiencies can cause shedding and weak hair.
What Supplements May Aid Hair Health?
Certain supplements can support hair growth, strength, and thickness when dietary intake is insufficient or when specific deficiencies exist. These supplements work by providing essential nutrients for hair follicle function, structural protein production, and scalp health.
Biotin (Vitamin B7): Commonly used for hair and nail strength. While biotin deficiency is rare, supplementation may help individuals with thinning or brittle hair—especially if a deficiency exists.
Iron: Low ferritin (stored iron) levels are strongly linked to hair shedding, especially in women. Iron supplementation should be guided by blood tests to avoid excess.
Vitamin D: Important for follicle cycling and immune regulation. Low levels are associated with alopecia areata and telogen effluvium. Supplementation is often helpful in deficient individuals.
Zinc: Required for protein synthesis and follicle repair. Zinc deficiency may cause hair loss and delayed regrowth. Excess zinc, however, can disrupt copper balance and harm hair.
Omega-3 Fatty Acids: Found in fish oil, these help reduce scalp inflammation, improve hydration, and support healthy hair shaft structure.
Collagen or Hydrolyzed Protein: Provide amino acids (especially proline and glycine) needed for keratin production and may improve hair strength and shine over time.
B-Complex Vitamins: Especially B12 and folate, which support cell turnover and red blood cell production, improving oxygen delivery to the scalp.
Silica and MSM (Methylsulfonylmethane): These support structural integrity of hair through collagen and keratin support, though evidence is modest.
Saw Palmetto: A plant extract that may help reduce hair loss in androgenic alopecia by blocking DHT (a testosterone derivative that shrinks follicles).
Supplements are most effective when deficiencies are present and should complement—not replace—a nutrient-rich diet and medical evaluation of hair loss causes.
Supplements like biotin, iron, vitamin D, zinc, omega-3s, and B-complex vitamins may support hair health by correcting deficiencies and improving follicle function and structural strength.
How Does Hair Health Vary With Age?
Hair health changes significantly across the lifespan due to shifts in hormone levels, follicle activity, and cumulative damage. These changes affect hair density, texture, growth rate, color, and overall resilience.
Childhood: Hair is typically soft, fine, and grows quickly. Conditions like cradle cap or tinea capitis (scalp ringworm) may occasionally affect scalp health.
Adolescence: Puberty increases oil production, sometimes leading to greasier hair and scalp acne. Hormonal changes can also trigger temporary shedding or shifts in hair texture (e.g., straight to wavy).
Early Adulthood (20s–30s): This is often a period of peak hair health, with optimal thickness and growth. However, early-onset androgenic alopecia may begin, especially in genetically predisposed individuals.
Middle Age (40s–50s): Hormonal shifts—especially during perimenopause, menopause, or andropause—can cause progressive thinning, slower growth, dryness, and changes in texture. Graying becomes more noticeable due to melanin loss.
Older Age (60s+): Hair density declines due to a reduction in active follicles. Growth slows considerably, hair becomes finer and more brittle, and scalp conditions like dryness or sensitivity become more common.
Throughout aging, cumulative exposure to UV light, oxidative stress, and chemical or heat styling also degrade hair structure, accelerating signs of wear. Regular, gentle care and nutritional support can help preserve hair health longer.
Hair health declines with age due to hormonal shifts, reduced follicle activity, slower growth, graying, and accumulated damage, especially after midlife.
What Role Do Genetics and Environment Play in Hair Health?
Both genetics and environmental factors play major roles in determining hair health. Genetics largely governs baseline traits and long-term patterns, while the environment shapes how well that genetic potential is expressed and maintained.
Genetic Influences:
Hair Type and Texture: Curliness, thickness, and density are mostly genetically determined and vary by ancestry.
Pattern Hair Loss: Androgenic alopecia (male and female pattern baldness) is strongly inherited. Genes influence follicle sensitivity to dihydrotestosterone (DHT), a hormone that miniaturizes hair follicles over time.
Hair Growth Rate and Lifecycle: The speed of growth and the duration of the growth (anagen) phase are influenced by your genetic blueprint.
Premature Graying: Genetic predisposition affects the age at which melanin production in hair declines.
Environmental Influences:
UV Radiation: Prolonged sun exposure degrades hair proteins, weakens strands, and fades color.
Air Pollution: Pollutants accumulate on the scalp, increasing oxidative stress and inflammation, which may damage follicles and accelerate aging.
Water Quality: Hard water and chlorine strip natural oils and disrupt hair structure, causing dryness and breakage.
Styling Practices: Excessive heat, harsh chemicals, and tight hairstyles can lead to breakage, traction alopecia, and scalp irritation.
Diet and Lifestyle: Nutrient deficiencies, chronic stress, and smoking impair follicle health and accelerate hair loss.
In essence, genetics sets the foundation for your hair’s potential, but environmental factors and lifestyle choices heavily influence how that potential is realized or compromised over time.
Genetics determine hair traits and risk of pattern hair loss, while environmental exposures and lifestyle choices shape hair quality, damage risk, and aging progression.
How Has Our Understanding of Hair Health Evolved Over Time?
Our understanding of hair health has progressed from superficial grooming practices to a deeper, science-based view that integrates dermatology, endocrinology, immunology, and nutrition. This evolution has led to better treatments, diagnosis, and prevention strategies.
Ancient and Traditional Views: Early cultures linked hair health to vitality, status, or spirituality. Remedies focused on oils, herbs, and rituals, without knowledge of hair biology or systemic factors.
19th–Early 20th Century: Hair care became more commercialized, emphasizing hygiene and cosmetics. Scientific exploration was limited to external treatments; internal causes of hair loss were poorly understood.
Mid–Late 20th Century: Advancements in dermatology identified different types of alopecia and linked hormonal and autoimmune factors to hair loss. Minoxidil and finasteride were introduced as medical treatments for pattern baldness.
Recent Decades: Research expanded into the molecular and genetic basis of hair growth, including stem cell biology and follicular cycling. We now recognize that nutrition, stress, hormones, inflammation, and even gut health affect hair.
Modern Technologies: Tools like trichoscopy, phototrichograms, and scalp imaging allow precise diagnosis. Genetic testing and personalized supplements are increasingly used for tailored hair care plans.
Holistic Approach: Today, hair health is viewed as a reflection of whole-body health. Dermatologists, endocrinologists, and nutritionists often work together to manage hair-related issues.
This evolving understanding has shifted the focus from treating symptoms to identifying and managing root causes—making hair care more effective, preventive, and evidence-based.
Hair health knowledge has evolved from cosmetic care to a science-based, systemic approach that now integrates genetics, nutrition, hormones, and inflammation in diagnosis and treatment.
