Colour B4 is not considered to be very damaging to the hair. It is a hair color remover that works by shrinking the artificial color molecules in the hair, allowing them to be washed out. While it can cause some dryness and frizziness, it is generally considered to be less damaging than other methods of color removal, such as bleach. However, it is still important to follow the instructions carefully and to use a deep conditioning treatment afterwards to help restore moisture to the hair. **

Colour B4 may not work for some individuals due to a variety of reasons.

It's also important to follow the instructions carefully and use the product as directed for optimal results. If Colour B4 does not work for a specific individual, it may be necessary to seek professional help from a hair colorist or stylist. **
