Using Herbatint on Relaxed Hair
If you have been relaxing your hair on a regular basis, it is likely that your hair has become very porous, which means that your hair absorbs the colour well but that it can wash out easily.
You could try putting the normal mix on the roots (1/2 colour, 1/2 developer) and then damped down the ends with a water spray and use the colour as a colour bath (1 part colour, 1 part glycol developer, 1 part Colourherbe Normalising Shampoo). You should make sure that after the colour is shampooed off you apply the Colourherbe Cream Conditioner on and leave for 5 minutes.
