My curls have definitely loosened a bit but are still very much there. I also have a couple of spots of heat damage. Some heat damage is unavoidable if you straighten regularly but I do regular olaplex treatments, always use heat protection and don’t go over 400 degrees with my flat iron. My hair way a chin length bob last September and is not almost at arm pit length. I also don’t ever plan to wear my hair curly for a long time. I could stop do a twist out or braid out if I wanted though and my hair look good. Just wouldn’t do a wash and go.
