Topical finasteride is a medication applied directly to the scalp to treat hair loss. Unlike oral finasteride, it delivers the medication locally, minimizing systemic side effects.
It works by inhibiting the enzyme 5α-reductase, which converts testosterone to dihydrotestosterone (DHT). DHT is a major contributor to androgenetic alopecia (male pattern baldness). By reducing DHT levels in the scalp, topical finasteride helps slow hair loss and potentially stimulate hair regrowth.
Studies show varying degrees of success, with some individuals experiencing significant improvement in hair density. The concentration of topical finasteride typically ranges from 0.025% to 0.1%. Application frequency varies depending on the product and physician’s recommendation.
Always consult a dermatologist or healthcare professional before using topical finasteride. They can assess your suitability for the treatment and provide personalized guidance on application and potential side effects.
While generally well-tolerated, potential side effects are less common than with oral finasteride and may include scalp irritation or inflammation at the application site. Regular monitoring is advised to track progress and address any adverse reactions.
