I just used the extra strength version of ColourB4 on my hair (it was dyed with Schwarzkopf Live Color XXL in deep black and I've been doing it for about 5/6 months) and my roots are a red/brown colour and the rest of my hair is still black.
Well firstly we need to establish if you’ve been applying high heats to your hair during the 5/6 months you have been using this Schwartzkopf colour.
When Colour B4 was launched there was feedback that Colour B4 was having no effect on Schwarzkopf Live XXL black, so It was put to the test using Regular Strength Colour B4 and it removed it from the hair without any problems.
However, this Schwarzkopf product is called ‘water resistant’ which means they have loaded it with silicone. This means you won’t have problems unless you have been applying high temperatures to your hair with irons in which case the silicone melts and traps the colour molecules inside the hair.
Another factor (which can prevent Colour B4 from working) is regular use of certain types of shampoos. Some famous shampoos contain high levels of silicone which create a barrier on the hair and prevent any other chemical product from working.
A good tip (before you next apply Colour B4) is to buy a build up removing shampoo, some bicarbonate of soda and some lemon juice. Wash your hair several times with the build up removing shampoo and then mix up 1 tablespoon of the lemon juice and 1 tablespoon of bicarb in a cup and apply it to your wet hair, comb through and leave for about 5 minutes. Then remove with the build up shampoo.
This above method can break down any build up on your hair surface and open your cuticle which will enable Colour B4 to get into your hair. If you have got a lot of excess silicone in and on your hair you want to try and get rid of that as best you can.Back to FAQ's ›
