K18's patented peptide is sized to reach deep into the hair and reconnect broken keratin chains – the ones responsible for strength and elasticity.
Used after shampooing, it repairs damage in four minutes and restores strength, softness, smoothness and bounce. No rinsing, and results build with every use.
Shampoo (don't condition), towel-dry, then work a small amount through damp hair. Leave for four minutes and style as usual – don't rinse.
