Librow, the eyebrow growth product from Lilash, promises to restore even the most overplucked and moth-eaten. Like its lash lengthening older sister, Librow contains a prostaglandin.

This is a drug that it used to treat glaucoma and was found to have a desirable side effect: it made lashes longer, thicker and blacker. Unfortunately, it can also have less desirable consequences such as irritation of the surrounding skin, staining of the skin, red and burning eyes and, in some rare cases, change of eye color.

Still, it works. Recent research has shown prostaglandins can stimulate head hair growth as well as eyelashes. Revitalash, another lash enhancer brand, has just brought out a hair growth product with prostaglandins as the active that we will be reviewing in full in a few weeks.

There are three botanicals in Librow: krameria, sarothamnus and walnut leaf. None have anything to do with hair growth, but in this combination, they are marketed together as something called Melscreen Black for preventing gray hair from looking yellow-ish by despositing dark pigments. The same three are also in Real Lash Mascara. I imagine that these dark pigments make lashes and brows look darker and therefore give the impression of being longer and thicker.

It seems likely that Librow will work as well as Lilash and given that it is used further away from your eyes there may be less irritation. Do post a comment if any of you have tried Librow.
