Androgenic alopecia
Androgenic alopecia is hair loss that primarily affects the top and front of the scalp. In male-pattern hair loss (MPHL), the hair loss typically presents itself as either a receding front hairline, loss of hair on the vertex of the scalp, or a combination of both. Female-pattern hair loss (FPHL) typically presents as a diffuse thinning of the hair across the entire scalp.

Male pattern hair loss seems to be due to a combination of genetics and circulating androgens, particularly dihydrotestosterone (DHT). The cause in female pattern hair loss remains unclear.

Common treatments include minoxidil, finasteride, dutasteride, or hair transplant surgery. Use of finasteride and dutasteride in pregnant women may result in birth defects.

Finasteride and dutasteride are most effective for men and postmenopausal women. Low-dose oral minoxydil may be used for a few selective cases.

Treatment ― OTC Drugs
In most countries, topical minoxidil preparations are available over-the-counter. There are some supplements that claim to be effective against hair loss, but most have not been scientifically proven to be effective.

    Although topical minoxidil, oral finasteride, and low‐level light therapy are the only FDA‐approved therapies to treat AGA, they are just a fraction of the treatment options available, including other oral and topical modalities, hormonal therapies, nutraceuticals, PRP and exosome treatments, and hair transplantation.
