Hello.. As you know ombre hair colouring is in fashion. Can some one tell me the best techniques to achieving this look. also I have a client that currently has blonde dyed hair root to ends, now she wants the ombre look but the ends are the blonde she wishes to have so how do I dye roots half way down? I am worried it will look like a straight line of colour. I was thinking of slicing from root half way down in small sections through-out the whole head, is this the best way? Thank you x
