Bain Extentioniste is a hair strengthening shampoo and a hair strengthening treatment that boosts strong hair growth starting at the roots. Bain Extentioniste is a shampoo to help hair grow not only in length but in strength with Creatine, an amino acid that reinforces the internal structure of the hair fiber. Weak hair and breakage-prone strands are strengthened with this hair strengthening treatment. The internal structure of hair is rebuilt and sealed to provide greater protection throughout its growth. Growing hair out has never been easier with our shampoo for long hair growth, Bain Extentioniste.
- Creatine: an amino acid that penetrates deep to reinforce the internal structure of the hair fiber
- Ceramide: provide surface recovery, assuring beautiful hair fiber as they smooth and soften
- Taurine: an amino acid with a protective effect on the hair fiber to help ensure visibly healthy and stimulated scalp environment
- Apply the shampoo to wet hair, massage well to release its rich, airy lather and aromatic fragrance.
- Rinse well and proceed to Fondant Extentioniste application.

So far so good!
[This review was collected as part of a promotion.] So far I really like this one, like all Kerastase shampoos this is very concentrated and I don't need a lot of it. I was a little worried to use this with my fine/oily scalp, but so far I haven't noticed my hair getting greasy any faster. It also has a nice lighter scent.

Protein Rich
Smell is nice, however this is not the product to try if your hair can not handle protein. My hair was dry and brittle after one was. I ended up returning this product.

Hi there! We are so glad you enjoyed the nice scent, but we are so sorry to hear that the product caused dryness and brittleness. Protein sensitivity can definitely catch hair off guard after just one wash, and we completely understand why you chose to return it. If you would like help finding a moisture-rich, protein-free alternative tailored precisely to your hair's needs, please feel free to reach out to our consumer care team or visit your local Kérastase salon!

This magic in a bottle has helped my hair grow significantly and gives it a great cleanse. My hair feels strong going into a conditioner/masque after use, I definitely think it’s helped reduce breakage and improve product absorption post use. Thank you Kerastase!

Real length and zero breakage
This shampoo has become a staple in my routine. My hair feels noticeably stronger and the ends are far less prone to snapping when I brush or style. It lathers well without stripping, rinses clean, and leaves my hair soft rather than coated. After a few weeks I can see the difference in how much length I'm actually keeping. Will repurchase.

I’ve been testing different Kérastase shampoos because I enjoy trying new products, but this one is definitely a favorite and I will keep repurchasing it. It gives my hair a fresh, clean feeling while still keeping it beautiful and soft.
I would definitely recommend it, especially for people who want a cleaner scalp and healthier-looking hair.

This will last you longer if you don’t have a husband. Unfortunately, my husband also uses it. That being said, I really like this product. It is a bit expensive but, on my greasy head, it works wonders and the smell is great. I really enjoyed it. I always buy new type and brand of shampoo so, after using the first one, I bought other shampoos but, my hair never felt the same so, had to buy it. So yeah, I will be repurchasing this for a long time.

Hydrating and not too heavy for fine hair
[This review was collected as part of a promotion.] I finally have found a shampoo that works the best for my thin blonde hair. It doesn’t weigh it down, cleanses very well without drying, and I don’t live a nightmare untangling my hair if I decide to skip conditioner. I love the smell, and a little goes a very long way.

Makes my hair grow
I have hair that I have never been able to get past my shoulders but with this shampoo and conditioner its almost mid back now after a year. I will be switching to the genesis to help with fall out but this has been great for getting real results
