Melatonin for hair loss is a treatment that uses the hormone melatonin to stimulate hair growth and slow hair thinning by extending the anagen (growth) phase of the hair cycle. Research suggests it may help regrow hair in cases of androgenetic alopecia (pattern baldness) and other forms of hair loss.
Melatonin, primarily known for regulating sleep, also plays a role in hair follicle function. It extends the anagen phase, delays follicular regression, and protects against oxidative stress-a key factor in hair loss. A 2020 study published in Dermatology Practical & Conceptual found that topical melatonin solutions improved hair density in patients with androgenetic alopecia.
Melatonin for hair loss comes in two primary forms:
A 2012 study in the Journal of Cutaneous and Aesthetic Surgery showed that a 0.1% melatonin solution increased hair density by 30% over six months in men with pattern baldness.
Melatonin is used for hair loss in cases where traditional treatments like minoxidil or finasteride are ineffective or cause side effects. It's particularly useful for those with:
Unlike finasteride, which blocks hormones, melatonin works by protecting hair follicles from damage and prolonging their growth phase.
Many people confuse melatonin's role in hair growth with its sleep-regulating effects. While oral melatonin supplements may improve sleep quality-reducing stress-related hair loss-they don't directly stimulate hair follicles. Topical melatonin, however, targets hair follicles directly through melatonin receptors in the scalp.
A 45-year-old man with mild androgenetic alopecia applied a 0.1% melatonin solution to his scalp twice daily. After six months, he noticed reduced shedding and increased hair thickness. A follow-up dermatological examination confirmed a 25% increase in hair density, with no side effects.
For those looking to prevent hair loss, melatonin may be a safer alternative to stronger medications. However, results vary, and it's essential to consult a dermatologist before starting any new treatment.
Melatonin for hair loss offers a promising, science-backed approach to regrowing hair and slowing thinning. While more research is needed, current studies suggest it's effective for both androgenetic alopecia and stress-related hair loss. If you're exploring treatment options, melatonin-especially in topical form-may be worth considering.
