Understanding your hair loss and what may help
At a glance
What It Is
A genetically driven form of hair loss caused by follicle sensitivity to the hormone DHT
How It Presents
Gradual thinning at the crown or temples, widening part, and increased shedding over time
What May Help
Scalp care, nutrition, red light therapy, and hormonal support approaches are commonly explored
Evidence Context
Research into light therapy and nutritional support for hair retention is growing and reasonably strong
See the evidence snapshotWhen to Seek Help
See a dermatologist if loss is rapid, patchy, or accompanied by scalp pain, redness, or fever
Explanation
Androgenetic alopecia (pattern hair loss) is the most common form of hair loss in both men and women, driven by genetic sensitivity to dihydrotestosterone. Nutritional approaches, scalp therapies, and hormone-balancing strategies are used alongside or prior to medical treatments.
Could this be you
Androgenetic alopecia shows up differently for everyone. Browse by how it tends to be felt — these are common experiences, not a checklist or a diagnosis.
Common experiences people describe — not a diagnostic checklist.
Why it happens
Androgenetic alopecia usually comes from a mix of factors rather than a single cause. These are common contributors — not certainties.
Genetic sensitivity to DHT causes follicles to shrink over time, making this condition strongly hereditary on both sides of the family.
Chronic stress may elevate androgens and disrupt the hair growth cycle, potentially accelerating shedding in those already genetically susceptible.
Hormonal shifts from thyroid issues or insulin resistance may worsen follicle sensitivity to DHT.
Poor sleep may raise cortisol levels, which some practitioners suggest could amplify hormonal triggers linked to follicle miniaturization.
Process
Management
A widely used over-the-counter option; a doctor may discuss whether topical minoxidil is appropriate, as some people find it may support hair retention and slow progression.
Prescription options such as finasteride or dutasteride are sometimes discussed with a physician for eligible individuals, as they may support slowing follicle miniaturization driven by DHT sensitivity.
Photobiomodulation devices designed for scalp use are increasingly explored; some practitioners suggest regular sessions may support follicle activity in androgenetic alopecia.
Ensuring adequate iron, zinc, biotin, and vitamin D is commonly explored, as some evidence suggests nutritional gaps may contribute to accelerated hair thinning in genetically predisposed individuals.
Consistent scalp massage and, under professional guidance, microneedling are approaches some people find may support circulation and the absorption of topical hair-support products.
Self-Care
Gentle shampooing, minimal heat styling, and avoiding tight hairstyles may help reduce mechanical stress on already-sensitive follicles.
Some people find that diets rich in leafy greens, fatty fish, and berries may support a scalp environment less prone to inflammation linked to follicle miniaturization.
Chronic stress may worsen hormonal fluctuations that accelerate DHT-related shedding; practices like meditation or regular walks may help moderate this response.
Thinning areas leave the scalp more vulnerable to UV damage; lightweight SPF products or hats may support scalp skin health over time.
Adequate intake of iron, zinc, and biotin is commonly associated with hair health; some practitioners suggest reviewing levels through a doctor before supplementing.
The Evidence
What research says about pattern hair loss and the approaches used to support scalp health and hair retention.
Well-researched condition with established and emerging options
Androgenetic alopecia is one of the most studied forms of hair loss, with strong evidence for medical interventions. Complementary and lifestyle approaches have emerging to moderate evidence for supporting scalp health alongside conventional care.
Topical and oral medical treatments for pattern hair loss are backed by robust clinical trial data. Nutritional approaches — particularly addressing deficiencies in iron, zinc, and biotin — have moderate supporting evidence. Herbal and mind-body strategies have smaller evidence bases but are increasingly studied as adjuncts to conventional care.
Androgenetic alopecia is driven by genetic sensitivity to dihydrotestosterone, which progressively shrinks hair follicles and shortens the growth cycle. Low-grade scalp inflammation may accelerate progression in some individuals. Clinical assessment typically considers hormonal, nutritional, and inflammatory factors together.
Nutritional therapy targeting micronutrient status has the strongest complementary evidence base. Some herbal preparations have shown preliminary results in small studies. Acupuncture and aromatherapy have limited but emerging data. These approaches are generally considered supportive rather than primary interventions, and evidence quality varies considerably.
Chronic stress can elevate hormones that disrupt the hair growth cycle. A balanced diet supporting adequate protein, iron, and micronutrient intake is associated with healthier hair retention. Stress reduction practices including mindfulness and yoga have moderate evidence for reducing stress-related hormonal activity, which may indirectly support scalp health.
Sudden patchy hair loss, scalp pain or tenderness, hair loss accompanied by fever, or rapidly spreading bald patches should be assessed by a qualified practitioner promptly. Hair loss following a medication change also warrants professional review. These presentations may indicate conditions requiring specific medical attention beyond lifestyle or complementary support.
A dermatologist or GP can assess hormonal, nutritional, and inflammatory factors and discuss evidence-based medical options. Complementary practitioners — including nutritional therapists and herbalists — can support overall health within a coordinated care plan. Inform all practitioners of any treatments being used to avoid interactions and ensure safe, consistent care.

FAQ
Androgenetic alopecia is the most common type of hair loss, driven by genetics and hormone sensitivity. It differs from hair loss caused by stress or illness, which is often temporary and reversible.
Some people find that red light therapy, scalp massage, and nutritional support may help slow thinning or support hair density. These approaches work best alongside, not instead of, medical evaluation.
Low-level laser and red light devices have been studied for androgenetic alopecia, with some research suggesting they may support follicle activity. Results vary, and consistent use over months is typically needed.
A dermatologist visit is worthwhile if loss is rapid, patchy, or accompanied by scalp symptoms. Early evaluation can help identify contributing factors and expand your options.
Nutrition alone does not reverse genetic hair loss, but deficiencies in iron, zinc, and certain vitamins may worsen shedding. Some practitioners suggest addressing nutritional gaps as part of a broader support plan.
