I had given up on brow serums and thought I'd have to rely on permanent brow makeup or tinting to fill in thinning brows. At the salon I went to, the aesthetician recommended Revitalash. The tint she applied looked darker/heavier on one brow, maybe because that brow was still fuller, but I looked out of balance so I wasn't going to go back. I did order Revitash and after 4-6 months do think that both brows look fuller though I still need to extend the thinnest part of the brow a bit towards the hairline with a pencil, then brush them up. I will continue using this product.
