Wanted: soft hair that won’t flake on dinner dates. My Exfoliating Scalp Serum is a gentle yet effective chemical exfoliant that breaks down dead skin and removes product build-up for less breakage and flake-age. Made with lactic acid to exfoliate and hydrate, witch hazel extract to soothe, and a prebiotic to nourish. Massage me into dry or wet hair and leave me on for 10 minutes before rinsing, while I exfoliate and nourish the place that takes all the heat. Your scalp, babe. Tip: Got curls or coils? Section your hair and use my handy nozzle to apply my serum directly to your roots.
