Male pattern baldness, or androgenetic alopecia, is a common inherited form of hair loss. It usually begins with recession at the temples, thinning on the crown or both. Hair follicles that are genetically sensitive to dihydrotestosterone gradually produce finer, shorter hairs until some follicles stop producing visible hair.
Recognising serious symptoms
The pattern is usually recognisable, but sudden shedding, patchy loss, scalp inflammation, broken hairs or loss of eyebrows may indicate another cause. Illness, major stress, rapid weight loss, iron deficiency, thyroid disease and some medicines can produce temporary hair loss. See a GP when the pattern is uncertain or the change is distressing before paying for commercial treatment.
Evidence-based treatment
Minoxidil and finasteride are the main treatments for male pattern baldness. They do not work for everyone and benefit generally lasts only while treatment continues. Finasteride alters conversion of testosterone to dihydrotestosterone and can cause sexual or mood-related adverse effects in a minority of users. A clinician or pharmacist can discuss suitability.
Cosmetic fibres, styling changes, hair systems and transplantation are other options. Scalp massage may feel pleasant but has not been shown to reverse genetically driven follicle miniaturisation. Protecting the scalp from strong sunlight becomes more important as coverage decreases.
Food and hair structure
Hair production requires sufficient energy, protein, iron, zinc and other micronutrients. A varied diet containing suitable protein foods, vegetables, fruit, whole grains, nuts, seeds and oily fish supports general nutritional adequacy. Crash diets and unnecessary food restriction can trigger additional shedding.
Supplements are unlikely to improve pattern baldness in someone without a deficiency, and very high intakes can worsen hair loss. Blood testing is more useful than guessing when iron, thyroid or vitamin status is suspected.
Useful supplements
Supplements should be selected for the individual rather than used automatically. Product directions and advice from an appropriately qualified professional should take precedence over general information.
| Supplement | Effects |
|---|---|
| Vitamin A | Supports normal immune function and skin-cell differentiation. |
| Multivitamin and mineral formula containing biotin, zinc, B vitamins, selenium and vitamin E | Provides nutrients involved in protein metabolism, scalp health, antioxidant protection and normal hair structure. |
| Plant sterols including beta-sitosterol | Described as reducing conversion of testosterone to dihydrotestosterone. |
| Vitamin C | Supports collagen formation and iron absorption in tissues supplying hair follicles. |
| Zinc citrate | Supports protein synthesis, immune function, vitamin A metabolism and scalp health. |
| Sprouted barley grass | Provides protein and antioxidant nutrients. |
| Spirulina | Provides protein and antioxidant nutrients. |
| Vitamin D | Supports normal immune and inflammatory regulation. |
High-dose vitamin A and excess selenium can themselves cause hair loss. Biotin may interfere with thyroid and cardiac blood tests; disclose it before testing. Evidence that beta-sitosterol supplements meaningfully slow male pattern baldness is limited, and products may interact with medicines.
Hair grows slowly, so genuine change is judged over months. A clear diagnosis, realistic expectations and consistent use of an appropriate treatment are more helpful than cycling through multiple “hair growth” supplements.
