Prohair is a prescription medication containing 1mg Finasteride, specifically formulated for men to treat male pattern hair loss. Each pack contains 30 tablets for a one-month supply. The medication works by blocking the conversion of testosterone to dihydrotestosterone (DHT), which is responsible for male pattern baldness. This medication is for use by men only and should be kept out of reach of children. It requires a prescription from a licensed healthcare provider. The tablets should be taken as directed by your physician, typically one tablet daily. Results may take 3-6 months of continuous use to become noticeable. Women who are or may become pregnant should not handle crushed or broken tablets due to potential risks to male fetuses.
