DetailsLiBrow is a cosmetic eyebrow enhancer which encourages eyebrows to grow, while darkening them as well. The company also makes an eyelash enhancer, which works similarly. Tis product cannot be applied to eyelashes as it is too strong. LiBrow simply needs to be applied to clean skin where eyebrow hair is desired and results will show in a few weeks. LiBrow can condition the hairs that are already there as well to make them healthier.
