    Hair feels amazing after use

    Posted by Jessica Horvarth on 18th Oct 2018

    Just started using this new Extentioniste line from Kerastase. I've been using their products for a while now but the clean conditioned feeling from this one is spectacular. Only after a few uses did I feel that there was a difference in my hair (I think its the strengthening properties but I am not entirely sure). I do recommend this product to anyone interested in trying it out, it will at the very least make sure your hair smell amazing.
