of course it is possible to lighten brown hair to blonde. HOWEVER! When the
hair has been dyed brown, black, violet or red.... beware of what lurks beneath as
the hair may be extremely stained with color.. inside and out. Avoid regret; by
conducting a strand test. Wrap several strands in lightener, and observe after 20 minutes.
If the hair has held on to too much depth. adjust your expectations.
I hope this information is helpful. B
I wonder if you might comment on your best approach to blonding a client. I have a client that is a natural level 6/7 and we have been deepening her for over a year with Shades Creme. she now wants to go back closer to her own color. I told her we couldn't do it in one visit, but curious how others would handle this transition.
