I have pretty dark hair and had been getting it highlighted for ~10 years. I hated when the highlights would grow out and I would have a line where my natural color started. I had the stylist use gloss (a haircolor that doesnt use any lighteners to strip the hair of its color) to blend the ‘line’ so it’s less noticeable and have been growing my hair out for a few months now and love that I don’t have to worry about re-highlighting it every month!
