When you die your hair do you need special shampoo everytime you wash?
it will make the color last longer if you use one for color treated hair. they arent anymore expensive than regular shampoo, and much better for you color job.
Its good to use shampoo and conditioner that are ment for people with dyed hair otherwise ones that arent meant for that will dull down the colour.
i dont and its still asthough ive never died it lol x
