Kérastase Ciment Thermique is the first heat-activated reconstructor milk for weakened hair. Thermo-activation specially developed to use with heat, increases the effects of the product by sealing the reconstructing active ingredients in the fibres. Vita-Ciment recreates the intercellular cement, strengthening the hair fibre from the inside. Also contains Vita-Topseal which is a resurfacing active ingredient and reinforces the natural external protective layer. Strengthens the hair fibre internally and protects the surface of the hair. Smoothes hair from root to tip leaving the hair firm, supple and energised.
