Finasteride versus Prostaglandin Analogues (Latanoprost and Bimatoprost)
Finasteride is the most commonly prescribed medication for the treatment of male pattern baldness (MPB). Finasteride provides an improvement in hair count and thickness. Results are typically notable in 6 months to 1 year with Finasteride 1 mg once a day. Finasteride is not approved for women with hair loss because it causes birth defects in male embryos.
Prostaglandin Analogues are medications used to treat ocular hypertension and glaucoma. However, these medications (Latanoprost and Bimatoprost) have been shown to increase hair growth. In clinical studies, Latanoprost significantly increased hair density. There was some evidence to suggest that this medication might also promote pigmentation of the hair.
Other treatment options for MPB include laser treatment, anti-androgens, Minoxidil (Rogaine), and surgical treatment. Other treatments are under investigation.
