I really like my set of hair caring” Olaplex “ . The small bottles of shampoo and conditioner have been useful during my trips. The care #3 I love very much. This balm is really good for hair. It helps to protect my weak hair. It makes the ends of my hair more alive. The spray #0 hasn’t been useful. Probably it’s not comfortable to have a wet hair to go sleeping. That’s why I couldn’t realise its benefits for my hair,because I haven’t used it at all. I have blond hair,which is very weak and damaged by colouring. So this set matched to my type of hair in the best way!
