i am a natural brunette(dark brunette) with a few greys so i home dye the same as my natural colour. i used to have blonde highlights but it was before i had ever dyed my hair brown so the highlights were on natural hair. i would like to go blonde. i know this will be a process of going gradually lighter a few shades at a time and am happy to take a stylists advice on how light to go wrt my skin tone and what will suit me. but the question is. because my hair is shoulder length hair and has been dyed brown for years, is it possible to go lighter or do i have to grow all the dye out. (if that is the case i will just stay dark as it would take years to grow it out to the same length)
