Finasteride is an oral medication primarily used to treat enlarged prostate glands and male pattern baldness, a common condition causing hair loss in men. It works by inhibiting the conversion of testosterone into dihydrotestosterone (DHT), a hormone linked to hair follicle miniaturization. While finasteride has been effective in preventing further hair loss and promoting hair regrowth for some individuals, it is not without its drawbacks. One significant concern is the potential for side effects, including sexual dysfunction, such as decreased libido and erectile dysfunction. Additionally, some individuals may experience mood alterations or other less common side effects. The long-term safety of finasteride is still a subject of ongoing research, and its use may not be suitable for everyone.

Minoxidil is a topical medication commonly used to treat hair loss, particularly in the form of a solution or foam applied directly to the scalp. It is believed to widen blood vessels, enhance blood flow to hair follicles, and stimulate hair growth. While minoxidil has shown efficacy in promoting hair regrowth for some individuals, it is not considered a definitive solution for everyone. One of the main drawbacks of minoxidil is that its effects are typically temporary, requiring consistent and long-term use to maintain any achieved hair growth. Discontinuation of the treatment often results in a reversal of its benefits. Additionally, some users may experience side effects, such as scalp irritation, itching, or unwanted hair growth in unintended areas.
