Pretty good [SEP] Probably will order medium brown. Dark brown turned my actual brow hairs black. I guess I’m more of a brunette after all. It definitely helps fill in patchy spots to make brows look fuller. Not sure how long it will last. Still use a little makeup to touch up and refine them, but not nearly as much as I was using before. Be careful when applying the front of the brows. I like to have the front faded which is tricky to get with this product.
