Finasteride is an FDA-approved medication used to treat male pattern baldness (androgenetic alopecia) by preventing the conversion of testosterone into dihydrotestosterone (DHT), the hormone responsible for hair follicle shrinkage. By reducing DHT levels in the scalp, finasteride helps to slow hair loss and, in many cases, promote hair regrowth. It is typically taken as a 1 mg oral tablet once daily and is most effective when used consistently over several months.
Originally developed to treat enlarged prostate (in a higher 5 mg dose), finasteride has become one of the most popular and clinically proven treatments for male hair loss. It is available under several brand names and generic versions, including Finpecia, Finax, and Propecia. Finasteride is well-tolerated by most users, though some may experience mild side effects. For best results, it’s recommended to consult with a healthcare provider before starting treatment.
What it treats?
Finasteride Treats Male Pattern Baldness: Finasteride is primarily used to treat androgenetic alopecia — the most common type of hair loss in men. It works by blocking the conversion of testosterone into dihydrotestosterone (DHT), the hormone that causes hair follicles to shrink and stop producing healthy hair.
It’s Also Used for Enlarged Prostate (BPH): At a higher dose (5 mg), finasteride is prescribed for benign prostatic hyperplasia (BPH) — an enlarged prostate. It helps improve urinary flow and reduce symptoms associated with BPH in men over 50.
Consistency is Key: Finasteride must be taken daily and consistently to be effective. Results for hair loss typically become noticeable after 3 to 6 months, and stopping the treatment may reverse progress.
It Works Best in Early-Stage Hair Loss: The earlier you start taking finasteride for hair loss, the better the outcome. It’s most effective in men with mild to moderate thinning, especially at the crown and mid-scalp.
It's for Men Only: Finasteride is not approved for use in women, especially during pregnancy, as it can cause birth defects. Women should avoid handling crushed or broken tablets.
Usage & Dosage
⚠️ Always read the label and follow dosage instructions
Finasteride is typically used to treat male pattern baldness and benign prostatic hyperplasia (BPH), depending on the dosage. For hair loss, the standard dosage is 1 mg taken orally once daily. For BPH, the recommended dose is 5 mg once daily. It can be taken with or without food, but it's important to take it at the same time each day to maintain consistent levels in the body. Regular use is key—skipping doses or stopping treatment can reduce its effectiveness and may reverse any progress made, especially in hair regrowth.
It may take at least 3 to 6 months of continuous use to notice visible results for hair loss, and up to 12 months for full benefits in BPH treatment. If no improvement is seen after that time, a healthcare provider may reassess whether to continue therapy. Finasteride is intended for long-term use and should only be taken under medical supervision. Women and children should not use or handle broken or crushed tablets, especially during pregnancy, due to the risk of serious side effects.
