It will gently strip away dyed colour from your hair without using bleach products, which is a great bonus and will protect your hair from damage. The Scott Cornwall Decolour strips out all kinds of permanent hair dye and you can reapply hair colour immediately. When you put a permanent colour on your hair the ammonia in it dries it out whilst the peroxide lightens the natural base colour. I seldom drop comments, however I read some of the comments here "Colour B4:Hair colour remover *WARNING*". One of the most lauded options around, it’s ideal for stripping back even the strongest of shades without damaging your hair.

A notable factor about Reduction Agents is they have a sulphur smell, which can often be likened to eggs. Now, if you are not really certain then I would suggest trimming off a small sample of your hair and ash semi that sample piece of hair first.Once the whole head is completely covered, cover your head with cling film; this generates heat and helps the hair cuticles open up to release the colour. This lightening of natural pigment is often not noticed until the unwanted permanent colour removes, then the lightened base is exposed. Comb the product through and develop for 10 minutes (rather than the standard 60) and rinse and buffer the hair just as instructed (for regular colour removal). If you wish to stay at the revealed lighter level but want to eradicate the warm tone, simply apply an ash toned temporary hair colour one shade lighter than your desired shade.

I was a little afraid to use this because my hair is very dry, damaged and it is dyed over and over again with permanent colours from brown to dark brown.However as the underlying blonde is starting to peep through it does appear that some of the unwanted dark molecules are now slowly fading. Taking less than an hour, this unique formula creates a lighter base which can be effectively and immediately recoloured. ColourB4™ won’t make your hair condition (necessarily) any worse, but it won’t make it any better either.

Colour B4’s Hair Colour Remover is an easy-to-use extra-strength hair colour remover that turns back the clock on unwanted shades, tones and multiple colours no matter how many of the above you’re trying to strip back.

A cold environment will slow down the rate ColourB4™ is able to shrink those artificial colour molecules. Once rinsed, apply half the bottle of the buffer solution and work it into the hair as you would a normal shampoo.Although not exclusively the case, this can occur due to product build up on the cuticle or silicone damage from previous products and colourants.

Easy to use and famed for working when other formulas have not been up to the task, this hair colour remover strips all kinds of shades including tough blues and purples.If any reduction agent colour remover is applied to a direct dye or fashion shade, the results would be unpredictable. Its preferable you wait at least 72 hours before doing this subsequent application to make sure any reoxidation has completely occurred before your next application of Colour B4. When colouring the hair to the same or to a darker shade new synthetic pigment molecules are added to the hair’s natural pigment changing its colour.
