### Fantastic Results!

TrendyMom

8 years ago

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

Ddavis

8 years ago

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.
