Medications for Hair Loss

Le Finasteride (Propecia®) is a prescription drug that has been available for many years. Its use is approved for men only. Scientific studies have proven its efficacy in controlling hair loss, and sometimes in stimulating new hair growth. It works by reducing the action of the Dihrydrotestosterone DHT, the hormone responsible for hair loss, but without modifying the level of the male hormone testosterone. The possible side effects are decreased libido and erectile dysfunctions but are usually mild and affect less than 3% of users. Its safety is well documented. It works better on early stages of hair loss, but is also appreciated in more severe cases because of the protection against future loss.

Topical Minoxidil (Rogaine®) 5% has also been used for many years and helps slowing down excessive hair loss. The popular foam formulation is recommended in both men and women: twice a day for men and only once a day for women.

Both medications need to be used for long durations of time to prevent te hair loss that may potentially occur after stopping their use. Both drugs are proven to work but not for all patients due to the genetic makeup of the individual.
