14 Editor-Reviewed Beauty Products You Need to Buy This August

Last month, I got scolded by a nail tech because of my addiction to gel manicures. Convenience and glossiness be damned . . . the rock-hard lacquers can take a toll on natural nails. I've been taking these supplements ($35) daily to strengthen my claws again. Each packet contains three pills — one for nails and two for hair and skin — that are packed with biotin and black currant seed oil (to promote hair growth). Not only are they gentle on the tummy, but I've already seen serious improvement.
