Can your stylist get you purple highlights in dark hair without using bleach?

Yes they can but only if you request that you don't want to use bleach or you can request them to bleach it but not touch the root like say you want the bleach half a centimetre away from your hair root. That's what I did; the first time I dyed my hair, my hair dresser said I had to bleach it and so she did, I told her not to make the bleach touch my hair root and she placed the bleach about a half a centimetre or a centimetre away and the colour looked fantastic!

If you really don't want bleach touching your hair at all, just tell your stylist not to use bleach but the colour might not be as vibrant and obvious and it might be a total waste of money if you used it without the bleach and the colour didn't show. But it'll most likely show brightly in the sun :) Hoped this helped! Good luck xo
