Prescription Medications For Hair Loss

Alopecia is the medical term for excessive hair loss from the scalp. It may be caused by genetics, medical conditions, or certain medications. The most common type of alopecia is called androgenic alopecia, or male pattern baldness, and is caused by genetics. Hair loss beginning at the temples and crown may begin in men as early as their teens. Men may then experience partial or complete baldness. Women may also experience hair thinning, however this rarely progresses to complete baldness.

Although there is no cure for baldness, treatments are available. Minoxidil (Rogaine) is available over-the-counter. This medication is a liquid that is applied to the scalp twice daily. Minoxidil works to cause hair regrowth, as well as to prevent further hair loss.  Hair that is re-grown from this treatment may not be as long or thick as previous hair. New hair does not continue to grow beyond the duration of treatment with minoxidil. The treatment may cause irritation of the scalp. Finasteride (Propecia) is a medication available with a prescription to treat male pattern baldness. This medication works by inhibiting the conversion of testosterone to dihydrotestosterone, which is a hormone that plays an important role in hair loss. This medication is not approved for use in women because of its potential to cause birth defects.
