I am a mixed girl (dominican, polish, and black) and have 3b hair. I have tried everything for my hair to become more managable. I did relaxers for a few years and my hair kept breaking so i just would'nt grow. I live i Philly and heard about this treatment, i went to the salon and got it done back in november and loved it. I have had 2 more treatments since then and my hair is shiny and growing. I will say i only wear my hair straight so i don't know how it look curly. This is the only thing that works for me and i don't think i will stop getting it. Have had to cut back on other things to pay for it but its well worth it.
