PRODUCT DETAILS

Complete the salon-level repair routine with this acid and heat care treatment — the conditioning counterpart to the Truest by S FREE Shampoo. Applied after shampooing, it delivers a concentrated dose of hydrolyzed Keratin, Silk proteins, and ceramides deep into the hair shaft to smooth, repair, and protect. The acid complex seals the cuticle for immediate improvement in smoothness and shine. Honey and botanical extracts including Haberlea Rhodopensis and beet root provide intensive nourishment, leaving hair soft, manageable, and visibly healthier. For seriously damaged, over-processed, or chemically treated hair, this delivers the recovery that regular conditioners can't.
