Sebastian Professional Drench Shampoo is a moisture-focused cleansing shampoo built for dry, frizzy, or chemically treated hair that needs extra softness and shine. Its cleansing base combines sodium lauryl and sodium laureth sulfate with dimethicone, a conditioning silicone that smooths the hair cuticle and adds slip during the wash, along with panthenol for added moisture. Sebastian markets it as safe for color-treated and chemically processed hair. It works best as one step in a broader moisture routine, ideally followed by Sebastian's matching Drench conditioner, and suits anyone dealing with everyday dryness or frizz rather than significant chemical damage. Because the formula contains traditional sulfates and a silicone, it isn't a fit for anyone specifically avoiding sulfates or silicones in their hair care, and the silicone can build up on finer hair over repeated use without occasional clarifying.
