OLAPLEX No. 9 Bond Protector, Nourishing Hair Serum

I bought this product when my hair was still died blonde, but I’m even using it after I went back to brunette. It is a wonderful heat protection that you apply before drying the hair. It protects and leaves your hair feeling super soft and healthy. It is a bit expensive but worth every cent. You only use a small pump before drying your hair. Can be used on any hair type and also for air drying because it protects against pollution as well.
