Nioxin 3D Expert Color Lock - 150ml.

Density treatment that neutralises residues, seals-in the colour and strengthens the hair to prevent breakage.

Nioxin Color Lock seals the cuticles and locks colour pigments into the hair immediately after the hair-colouring process.

Color Lock is a density treatment exclusively for in-salon use. It neutralises alkaline and peroxide residues without weighing down the hair.
