How to neutralise yellow tones on blonde hair

Why blonde hair turns warm

Light blonde hair can become yellow because of washing, heat styling, sun exposure or pollution. Blue and purple pigments help correct those unwanted reflections visually, but they work best when used occasionally and with control.

The role of the Kérastase mask

The Kérastase Blond Absolu mask is described on Ksmetik as a rich mask with blue and purple pigments, designed for cool blondes and the neutralisation of yellow reflections. It can be useful when the blonde looks too warm between salon visits.

Frequency and balance

A neutralising mask does not need to be used at every wash. It is better to apply it when the tone really needs correction, then alternate with a nourishing mask if the hair lacks softness or comfort.
