ColourB4 Hair Colour Remover

It is designed to remove both permanent and demi-permanent hair colors. However, it is not effective on direct dyes, such as semi-permanent fashion colors (like bright pinks or blues) or henna-based products.

No. The formula is free from ammonia and bleach, meaning it works by shrinking the dye molecules rather than stripping your natural pigment. It is a much gentler alternative to traditional color-stripping methods.

You should set aside at least 60 minutes for the processing time alone. After that, you will need additional time for the thorough rinsing and buffering steps required to ensure all the dye molecules are washed away.

Yes, you can re-color your hair on the same day. However, it is recommended to choose a shade that is one or two levels lighter than your target color, as hair can sometimes absorb new dye more intensely immediately after a removal treatment.

Colour B4 removes artificial dye, but it cannot restore your hair to its original virgin shade if you have previously bleached or lightened it. It will reveal the color of the hair underneath the dye you are currently trying to remove.

Because the product works by shrinking dye molecules, it can have a distinct, sulfur-like scent during the application and rinsing process. This is a normal part of the chemical reaction and will dissipate once your hair is fully washed and dried.
