I used it weekly because I didn't think it would cause harm. I did continue with moisture treatments and protein. My hair became very dry after protein treatment and I used steamer with moisturizing conditioners for 3 weeks. Now the texture is balanced, but I am still experiencing breakage. I stopped using Olaplex completely. I have about 1 inch of new growth, followed by 3 inches of texlax (from the Olaplex) and then 7 to 8 inches of fully relaxed ends. I believe that the tex lax is causing the breakage. I am considering doing a full Olaplex, touchup with some Olaplex no 1 pulled through to tex lax area. I am scared out of my mind.
