100% I know that using this product is why the ends of my hair have FINALLY stopped breaking off Water on the ends of your hair are not good for it to penetrate the cuticle and continue to damage your hair. You can seal your hair with this oil (much less in cost than what I use during styling) and it smells great too! If your hair is super dry and damaged I would recommend putting this on all the ends of your hair (away from your scalp) LTKSaleAlert LTKBeauty
