Finasteride is a prescription medication commonly used to manage male pattern hair loss, also known as androgenetic alopecia. It works by reducing the conversion of testosterone into dihydrotestosterone (DHT), a hormone associated with the miniaturization of hair follicles in genetically susceptible men.
How Does Finasteride Help With Hair Loss?
Finasteride for hair loss may help slow ongoing hair thinning and support the maintenance of existing scalp hair. Some men may also experience hair regrowth, although individual results vary. Treatment generally requires consistent use for several months before improvement can be assessed.
Who May Benefit From Finasteride?
Finasteride is primarily prescribed for adult men with male pattern baldness after a doctor has assessed the cause and pattern of hair loss. A proper diagnosis is important because hair loss can have several causes and may require different treatments.
Important Considerations
Finasteride should be taken only as directed by a qualified healthcare professional. Possible side effects include decreased libido, erectile difficulties, and ejaculation-related changes. Mood changes and other less common effects should also be discussed with a doctor.
Pregnant women should not take finasteride, and they should not handle crushed or broken tablets because of potential risk to a male fetus.
