Does Finasteride help to regrow hair? Or does it only help to prevent you from losing the hair you currently have?

Propecia (finasteride) is not a cure for male pattern balding but it slows down hair loss and sometimes regrows new hair.

Finasteride can help regrow hair and improve density. It will take up to 6 months to see results and you'll need to continue use to maintain results. I recommend getting a formal evaluation with a hair loss expert to go over your condition and advise you on best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

Finasteride should do both in roughly half of male patients. This is an ongoing treatment, therefore daily usage is required for efficacy. You may want to be evaluated for grafts, which are a permanent solution.

Studies with finasteride showed that about 40 % of users will regain some hair density and 50 % will have their hair loss slowed or stopped. So yes, a proportion of men are expected to get an improvement in density.

It is difficult to answer your question without knowing if you are male or female. Finasteride works well in young men in their 20s and I have seen occasionally young men reverse their hair loss. It is usually ineffective in premenopausal women
