THE KERASYS DIFFERENCE

17 Amino Balance: The Science of Stronger Hair

Your hair is nearly 90% protein. So when it feels weak, dry, or damaged, it's a sign your strands have lost the amino acids that once held them together. Kerasys built its 17 Amino Balance formula around this exact problem — combining hydrolyzed wheat, soy, and rice proteins, broken down into 17 individual amino acids like lysine, arginine, glycine, and cysteine, small enough to actually penetrate the hair shaft rather than just sit on the surface.

Each wash works on two levels: the amino acids fill in the gaps left by heat styling, coloring, and everyday damage, while the proteins coat and smooth each strand, locking moisture in and frizz out. The result is hair that's not just rinsed clean, but genuinely repaired — softer, more resilient, and visibly shinier from the very first use.

Whether your hair is fine and flat, dry and damaged, color-treated, or simply craving some extra TLC, Kerasys has spent years refining formulas for every hair type and concern, so there's a perfect match for you.
