Hi Scizzorqueen.

Do you mean the colours such as crazy colours (where the hair is pre-lightened and then the colour applied directly over the top)?

If so, then yes. I have mixed powder bleach with warm water and rubbed like hell to get it out. The ammonia opens the cuticle and the rubbing creates friction and heat without further damage to the hair.

The problem though, is that most of these "hot colours" contain direct dyes which also stain the cuticle. So even though the pigment is removed form the cortex, it remains as a stain to the cuticle (kind of like how our fingernails get stained if colouring without gloves).

You either need to consider the stain when re-colouring the hair (in the same way that you would consider an underlying pigment in the natural undercoat) or do the following -

DO NOT LET THIS GET ANYWHERE NEAR THE SCALP!!!

Mix a small amount of non-biological washing powder with warm water in a mixing bowl to form a paste, and then, put some gloves on and apply the mixture to the hair, forcing it in to the sections.

Leave for 15 minutes with a developing cap.

Rinse well for at least 5 minutes at the backwash and then apply a conditioning treatment.

It works very well, but leaves the hair feeling very rough so the treatment afterwards (as well as homecare) is recommended.
