Drench Deep Moisturizing Treatment is a rinse-out hair mask from Sebastian Professional made to deeply hydrate dry, chemically treated, and frizz-prone hair. Behentrimonium chloride and a blend of fatty alcohols condition the hair shaft while hydrolyzed silk, jojoba seed oil, and rice bran oil add slip and softness, leaving hair feeling silky and conditioned rather than just temporarily smoothed.
It's designed as a quick, once- or twice-weekly deep-conditioning step rather than an everyday conditioner, and works well on its own at home or alternated with an in-salon Drench service for hair that needs ongoing moisture repair.
