Latanoprost is the therapeutically equivalent drug to bimatoprost, which is the active ingredient in the eyelash-growing product, Latisse. Initially used to treat glaucoma, it was found that it has a positive side effect: eyelash hair growth and density.
According to the American Academy of Dermatology, Latanoprost could be found useful in stimulating hair follicle activity and treating hair loss. After a study with the Department of Dermatology and Allergy at the Clinical Research Center for Hair and Skin Science in Berlin, Germany, it was found that Latanoprost significantly increased hair density during a 24-week time period compared to the baseline and the placebo-treated areas.
While Latanoprost is not yet FDA-approved, this drug is one of the front-runners for current research on being used as a reliable treatment for alopecia.
DISCLAIMER: If you are hyper-sensitive or allergic to prostaglandin, you should NOT use Latanoprost. Severe allergic reaction may occur.
