I have very sensitive skin & about 5 years back my regular/mild relaxers got too much to take. Since then I've used Mizani Sensitive Scalp Formula. A few months ago, I had problems with the Mizani not giving me good results. My stylist did a lot of research & decided that I would be a good candidate for Elucence. This week we did the switch to Elucence, which was even more mild than the Mizani (and smelled wonderful), I got much better results with it. You can see from my hair album link. Frankly I was amazed.
