Developed to defend dyed hair from the sun’s rays, Sachajuan’s Hair in the Sun Leave-in Lightweight Serum is a multi-benefit formula that protects against brassy tones caused by UV and pool water. Made with UV filters and TED (Trisodium Ethylenediamine Disuccinate), the featherlight hair serum minimises the risk of irritation and scalp sensitivity, nourishing the strands for a soft, hydrated feel. Plus, the formula acts dually as a styling cream, locking your tousled beach waves and curly styles into place.
