Hi i want to go my natural gray. Will this remove all colour build up? I have a dark brown/violet colour at the moment.

I had dyed my hair very dark brown for over 10 years to cover my grey. This product stripped out every bit of dark dye & still left my hair in good condition. It smells awful but really works.

I have Dyed Dark Brown hair it is naturally medium brow. if I use this can I dye it a different colour straight away

How soon can I re-colour after using ColourB4?Immediately, due to the Buffer step (Part C) the hair is left at a suitable pH level for safe re-colouring. However, there are several factors which come into play that can dictate how well your next colour application develops. If your previous hair colour application (or applications) have made your hair porous this will become evident after using ColourB4. If you wish to apply a new colour application to porous hair, always select a non peroxide semi-permanent product and apply to wet hair, checking the colour's development every few minutes. Porous hair will grab colour faster. To achieve the best results after using ColourB4, always re-colour with a Level 1 temporary (or true semi) hair colour in your desired shade, and rest the hair for several weeks before applying the permanent (peroxide based) alternative/variant. This allows the porosity in your hair to normalise and take permanent colour evenly.

how long does the smell last

It’s lasted almost two weeks for me so far. Horrendous eggy smell as soon as my hair gets the tiniest bit damp (shower, sweat at the gym, rain).

What's the difference between this and bleech?

Bleach removes all pigment from the hair (natural or chemical) and also doesn't work too well with semi permanent colours. Whereas colour b4 just removes chemical pigment (aka dyes) and just leaves you with your base colour whether that is bleached hair or your natural colour. Colour remover is also waaaay less damaging to your hair than bleach
