Xalatan (Latanoprost) for Regrowing Hair?

Hi doctor,
I just wanted to know your opinion on xalatan (Latanoprost) on its effectiveness to regrow hair?
I ask because I have sparse eyebrows from overpluckig and was wondering if theirs anything I can do to regrow them.

Thank you

Xalatan is a prescription drug used to lower eye pressure in people with high inner eye pressure or open-angle glaucoma. The stimulating effect of this medication on the growth of eyebrows and eyelashes and pigmentation of hair was accidentally found in a group of patients who were using topical Xalantan for treatment of glaucoma. This finding was published in the American Journal of Ophthalmology in 1997. Since then, many other studies have been conducted to evaluate the effect of Xalantan on hair growth in human and animals. Here’s one — Prostaglandin analogs for hair growth: Great expectations

Despite the above mentioned reports, Xalantan is currently not one of the recommended medications for prevention and treatment of hair loss and probably more studies are needed for its efficacy and side effects in comparison to other available hair loss medications.

As for the second part of your message — sparse eyebrows from over-plucking will likely result in permanent hair loss over time. Aside from using eyebrow makeup, hair transplantation is a possible option.
