Use after applying the wrong colour, to prevent colour build-up, before any salon colour service or when switching colourant brands. Wash away your unwanted artificial colour Colour B4 Regular For All Hair Colours is a hair colour remover which is the most convenient & effective way to reverse an undesirable hair colour application. B4 regular is ideal for the removal of a fresh colour application or an unwanted shade or tone. How It Works Colour B4 shrinks the aritifical dye molecules in the hair, enabling you to simply wash them away. Colour B4 does not touch your natual hair pigment so you are left with the colour which lay beneath your artifical shade. Safe & Gentle Colour B4 contains no bleach or ammonia & the after treatment buffer means you can re colour your hair immediately after applying & still achieve your desired result. Please Note: Colour B4 takes you back to your natural or lightest shade. It will return you hair to its natural colour if the artifical hair colour applied is darker than your natural level. If you have previously bleached or lightened your hair, Colour B4 is unable to return the (original) natural pigment. If you have applied a very dark or fashion colour (such as vibrant red or black) to bleached, porous or grey hair, the cuticle may have been permanently stained. Colour B4 cannot remove cuticle staining.A preliminary patch test according to the accompanying directions should be made first.
