okay, so i have had black hair previously, and i let it grow out to the point it was my natural colour for about half my head of hair and dark brown for the rest and in the summer i dyed it very red, then i dyed it permanent black, the red was still trying to come through and turned it slightly purple in some areas, so i put on a non-permanent black from calirol's nice n easy.. its starting to turn brown in some areas which is good. ive been using tresemme deep cleansing shampoo and every time i wash out the shampoo the water will turn a dingy colour - hopefully this is a sign that the black is being drained out. but id really like to dye my hair blonde around the time of summer 2010 or early autumn. my natural hair is quite fine and its natural colour is a dirty blonde with natural light hilights in. i want to dye my hair a light tone of blone, adding some lowlights so it doesnt look rediculously fake. will this damage my hair? what are the best products to stripping and cleansing hair? head and shoulders doesnt seem to work for me so please dont reccomend it. thankyou!
