    TLDR Latanoprost, a glaucoma treatment, was found ineffective in treating hair loss in eyebrows and eyelashes.
    In a study conducted 13 years ago, researchers evaluated the efficacy of latanoprost, a prostaglandin F2 analogue used for glaucoma treatment, in treating alopecia areata of the eyebrows and eyelashes. The study involved 26 patients with symmetrical eyelash and eyebrow alopecia areata, who were treated over 4 months with topical latanoprost on one side, while the other side was left untreated. The results showed that only one of the latanoprost-treated cases exhibited partial hair regrowth on the treated side. The relationship between hair regrowth and latanoprost application was not statistically significant (P = 1). Therefore, the study concluded that topical latanoprost has no efficacy in the treatment of alopecia areata. The researchers suggested further studies with a larger sample size, longer study duration, and higher concentration of medication.
