Fantastic Results!

I’ve using Bain Extentioniste Shampoo since it was launched and made available for purchase. This product is amazing! I have fine and thinning hair due to Lupus. I am amazed that I have regrowth and my hair doesn’t look “frizzed” anymore. The density of my hair appears fuller and healthier. Also, I have incorporated the Fondant Extentioniste and Masque into my hair routine. Finally, I wash my hair and use heat tools everyday with these fabulous results. I’m so happy! Thank you for saving my hair!

So-So

I have been using Kerastase products for 12 years. I have tried many of their products and while I have my favorites I'm usually not overall disappointed, but that is not the case with this shampoo. It does have a good lather and gives the hair a very clean feeling, but I have fine, slow growing, color treated hair (which is why I bought this product) and it seems to be drying my hair and scalp out more than helping my hair grow unfortunately. Spending so much on a product that doesn't live up to it's name is frustrating and disappointing.

Q: Hello! I have an oily scalp and fine hair that is easily weighed down. I’m wondering how this product does with oily scalps. I typically use silicone free to avoid buildup on my scalp, but I know this is not silicone free. How lightweight is it?
