The pH level helps to open the cuticle layer so the colour can achieve its end goal. For this reason, the SHADES in CODE will have a pH level on the alkaline side of the scale, although this alkalinity will vary depending on the SHADE and will change when mixed with KEVIN.MURPHY Activators.

NOTE: When discussing pH in a class format we advise to not discuss pH exact numbers as this makes colourists compare pH levels with other brands.
