Now I have been dying my hair for many years and I was no stranger to using colour b4 products or similar products like them. Seeing as I have used these so many times I thought I could give my fair say on this hair colour remover. I must start by saying I am not the biggest fan of this but I can see why it’s so popular.
Colour B4 is a hair colour remover and it basically works by shrinking the dye molecule back to its original size. Different factors can affect the results though.
