During treatment, keratin is infused into the hair which penetrates deep into the damaged cuticle, giving the hair a naturally straight and smooth look, leaving even the most porous hair silky, shiny and healthy. It delivers fabulous results at affordable prices and can be performed conveniently with minimal steps. It can even be performed on chemically treated hair and on the same day as coloring. It is a semi-permanent treatment fading naturally over 36-40 washes.
