Androgenetic alopecia is a type of hair loss that is mediated by the presence of the androgen dihydrotestosterone (DHT) . It is the most common form of alopecia in men and women, and almost all people have some degree of androgenetic alopecia. The hair loss usually begins between the ages of 12 and 40 years and is frequently insufficient to be noticed, but visible hair loss occurs in approximately one half of all persons by the age of 50 years. Women with androgenetic alopecia do not have higher levels of circulating androgens, but they have been found to have higher levels of 5α-reductase (which converts testosterone to dihydrotestosterone), more androgen receptors, and lower levels of cytochrome P450 (which converts testosterone to estrogen) .

There are several treatment options available for androgenetic alopecia, including topical solutions, natural products, and oral supplements. Minoxidil is a common topical solution used to treat androgenetic alopecia, and it is available in different concentrations. Some natural ingredients have also been used in the treatment of alopecias with an unknown mechanism of action. DHT-inhibitors and hair growth stimulants are included in some oral supplements.

While there are treatment options available, it is important to note that some treatments may have side effects, and compliance and financial considerations should also be taken into account. Hair loss can negatively impact self-esteem and overall quality of life, so it is important to consult with a healthcare professional to determine the best treatment plan for each individual case.
