I alternate shampoos one week it will Mizani, the other would be Nexxus Therappe. I use Dudley's Hair Rebuilder for 10-15 minutes with heat and followed by Mizani Moisturfuse for 15 minutes without heat. I have had no problems with this method. Another user of Dudley's Hair Rebuilder is Tracy. Dudley's Hair Rebuilder is a Penetrating Conditioner it rebuilds badly damaged hair. For me, it really works. I feel my hair is stronger with both Dudley and Mizani and have been using this for the past couple of months now. I am now on my 10th week of a relaxer (I plan on getting the twists in January) and I am shocked that my hair is not shedding at all. Usually after the 7th week my hair is crying for a touch-up and will start to shed. I can really tell by how much hair I see on my bathroom floor. But now, I see no hair at all. Try it. Tell me how you like it.
