It can totally be frustrating to say goodbye to old, damaged strands if the growing-out process is taking longer than expected. But you don't have to be frustrated waiting on healthier, new hair to grow in if you use Bain Extentioniste Shampoo. This strengthening shampoo works to transform the strands you already have by recovering the hair fiber's perfect condition, sealing the cuticle from root to ends, and ensuring a healthy scalp.

How to Use
Wet hair thoroughly. Apply and massage through the scalp and hair in circular movements. Emulsify and rinse thoroughly. Repeat this application and leave in for a few minutes. Lather by adding a little water and gently emulsify before rinsing thoroughly.

Rated 5 out of 5 by from Best shampoo Love this shampoo! It’s by far my favorite. My hair is so incredibly soft and is so much more healthy since I started using it a month ago. I won’t buy any other kind!

Rated 4 out of 5 by from Love this! I bought this hoping to make my hair longer. I've only been using it for about a month, so hard to tell if it's working, but I have loved it so far and am now buying the conditioner to go with!

Rated 5 out of 5 by from Love this product line I am thrilled with the Kerastase Resistance line. I'm using the shampoo, conditioner, and thermal protection. I'm over 60 and had been so distressed at how old my hair was looking -- dryer, more wiry. This line has truly made may hair look and feel younger. Some of my natural wave has even returned!

Rated 5 out of 5 by from Great Product I use only Kerastase products. The extentionise line is amazing. I use all the products in this line. My hair looks shining, grows fast and is very healthy.

Rated 5 out of 5 by from Amazing! I tried a sample of this shampoo, that was sent to me with my other Kerastase purchase, and after that I had to get the full size of this shampoo and conditioner! I am growing out my hair long after bleaching it, now I am back to my natural color and only do a little bit of colour (dark highlights) at a hair salon, where I can do Kerastase treatment. This shampoo is amazing at keeping my length healthy. Great addition to my hair routine!

Rated 4 out of 5 by from Smells amazing I was a bit skeptical to try a new product - but I had to have my hair dyed twice within a span of two weeks (blonde balayage and then a color correction) As you can imagine my hair was feeling a bit tired and dry. I used this shampoo and not only did it smell great, but it brought life back to my hair. I used it with the mask and the leave in treatment that are also part of the collection. Would recommend .

Rated 5 out of 5 by from So nice! This is admittedly out of my budget but I splurged in this shampoo and the matching conditioner and it’s amazing! My hair is fine but color treated and damaged and it makes it so easy to brush post shower. I love the fresh clean scent. It smells mildly tropical. I would repurchase during a sale again. Thanks!

Rated 5 out of 5 by from Great product line Been using for several weeks, I wash/treat hair once a week. Due to having done very light blond balayage, foils and touch ups for two years, my hair is now very damaged (dry/thinning/brittle/broken). I purchased Resistance Bain Extentioniste, Resistance Mask Extentioniste and Resistance Ciment Thermique. These specific products made a huge difference overall on my hair and scalp on the first try, LOVE IT!

Rated 1 out of 5 by from Bought the whole set, no noticeable difference! Several months ago, in high hopes of growing stronger and therefore longer hair, I bought (at great cost) Bain Extentioniste Shampoo, Conditioner and Serum. I should know better, this is in no way a magic potion to stengthen and grow hair! These products certainly made NO difference. None. Not a bit.

Rated 5 out of 5 by from Fixed my color damaged hair in Colorado climate I was recommended this shampoo from my stylist who wanted to first repair the strength of my hair before fixing any color correction. I live where the humidity is around 20% everyday so it's extra harsh on my hair. On top of the dry air, my hair was messed up twice by people who did a bad job with balayage. I seeked help from another stylist who then told me to use this shampoo. I paired it up with my favorite hair masque conditioner by J Beverly Hill. Both work really well together and my hair feels stronger, feels softer and looks a lot better.

Rated 2 out of 5 by from Not my favorite.... I love Kerastase products and have been using them exclusively for 11 years. This is not my favorite. I actually think my hair is dryer than before. I am going back to the Magistrate.

Rated 4 out of 5 by from Love Kerastase products, prefer Bain Therapiste I have only been using Kerastase products exclusively for 2 weeks, but have since built a small collection since my first purchase. My hair is long, thick, medium-texured, wavy-curly, color-treated and Balayage-highlighted. Most of my hair is fairly healthy, but the highlighted areas tend to be dry with some split-ends. My very first purchase with Kerastase ruined me (in a good way). Before purchasing the Bain Exentioniste shampoo, I had purchased the Bain Therapiste shampoo along with the Fondant Extenioniste conditioner (these were recommended by the diagnostic tool). I fell in love with the Bain Therapiste shampoo and Fondant Extentioniste conditioner combination because it left me with a Brazilian blow-out silky, glossy result -- it felt like I had left the salon!! Then, after doing some research, I thought that maybe I should pair the Bain Extentioniste Shampoo with the Fondant conditioner or extentioniste hair mask (which I later purchased). I took the online diagnostic tool test again providing the same information, but including the desire for longer hair -- it recommended the Bain Extentioniste shampoo, Fondant Exentionise conditioner, etc. Well, my experience with the Bain Extenioniste shampoo was just okay, I probably wouldn't buy it again. Process: Upon opening, I noticed that the product was clear (not creamy like the Bain Therapiste). The smell was pleasant, but not as great as the other products. I used a quarter sized amount to my scalp, then another quarter sized amount through my lengths (second wash) and lathered them both in. I noticed that this product builds up a big lather (very sudsy), unlike the creamy Therapiste. After shampooing I combed my hair before conditioning and noticed my hair didn't tangle (very good!). Then, I conditioned with the Extentioniste mask (not to be confused with the Fondant conditioner) and then after towel-drying, I applied a hazelnut sized amount of the ciment thermique (which I love). When blow-drying, I noticed my hair was very dry and frizzy. First, I blamed the mask, but then questioned the shampoo. I had plenty of Kerastase styling products to soften my hair, but it wasn't the same as the glossy, smooth locks that the Bain Therapiste shampoo left me with. So, then, a day later I experimented with a different combo: Bain Extentioniste shampoo with the Fondant Extentioniste conditioner + ciment thermique -- this combo gave me a better result, but my hair was still slightly dry, but definitely much smoother. Then, I tried another combo (the Therapiste shampoo with the exentioniste mask -- final result gave me glossy locks). I concluded that maybe my balayage highlights don't respond well to the shampoo, or the shampoo is high in sulfates which left me with a dry hair result reminiscent of the cheaper shampoos you can buy anywhere. This afternoon, I went back to my original Therapiste shampoo and Fondant conditioner combo that I loved so much, and surprise, surprise...I have another glossy-locks, magazine-ready Brazilian blow-out salon experience in my bathroom! Conclusion: I think I am going to stick with the Bain Therapiste shampoo. While the Bain Extentioniste might work better for other hair types, I don't think it serves those with highlighted hair well. I would recommend this to friends who don't have highlighted hair or overly processed hair, or this shampoo might work those with more oily hair types. While I have given stellar 5 star reviews on practically every Kerastase product, this one only gets 4 stars. It's still a good shampoo, but it just didn't "wow" me. Going to return this back and hope they can exchange with a bottle of my favorite Bain Therapiste shampoo.

Rated 1 out of 5 by from Not good for highlighted hair! I have only used this two times so far, but I have highlighted hair and the diagnosis quiz said this is the best for my hair. I have such a hard time getting through my hair with this shampoo. It just doesn't work for hair that has been highlighted and you have to use a lot since it is such a thin shampoo. I unfortunately bought the large size bottle and I am regretting my expensive decision. Also - Kerastase usually has such an awesome smell - this one does not. It doesn't have a smell at all.

Rated 5 out of 5 by from 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!

Rated 3 out of 5 by from Works but... it makes my hair SHED a lot Bain Extentioniste did help my hair grow longer and faster. I received a bad cut and my hair was very short. I saw results with Extentioniste products after a couple washes. Unfortunately, it makes my hair shed a lot. More than I've ever shed in my life. It might be because this shampoo tangles my hair so much and makes it very difficult to comb. I have fine hair, and I do not get knots that often. But when I use this shampoo, my hair becomes a bird's nest. I enjoyed the lengthening benefits of the shampoo so much, I tried a workaround. I would condition my hair before shampooing with a Nutritive conditioner. Then use Extentioniste shampoo and conditioner to finish. But it became too much work. The lengthening benefits no longer out weighed the amount of hair I lost.

Rated 4 out of 5 by from Amazing shampoo! I’m someone who is picky about the shampoos and things I use on my hair. I have been using the same brand for years now. But, after trying this shampooo I believe I’m going to have to switch my hair routine. This shampoo didn’t make my hair feel like straw which is what I was afraid was going to happen. It made it feel silky and smooth. Plus pairing it with the matching hair mask was amazing! [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Kerastase Shampoo 1st and foremost I have dry curly hair that frizzes easily and is colored. Also it breaks pretty easy too, so I tend to co-wash it or wash it once every two weeks with a shampoo. Kerastase to me is known for their products on a higher end with salon quality. I was ecstatic to give this a whirl,especially since it's supposed to help with hair that seeks a healthier length (hello breakage). It's got taurine in it and supposed to help strengthen and fortify hair. PROS-Smells great and its not overbearing. Less is more with this product. Made my hair feel clean without feeling super coarse or like hay. CONS-It will be on the pricier side of shampoos but I feel like you don't need much so it would last a long time anyways. When I first poured into my hand I didn't think I had enough but omg, it spread so easily through my thick tangled locks and the little bit that I did use worked itself evenly and easily to my roots leaving my hair satisfyingly clean.The smell is hard to explain..pretty but not overbearing. My hair didn't feel like it was super dry/damaged and hay like it normally does with shampoos. My hair was manageable when after using it. I didn't really feel like much was missing from this product at this point. I would purchase again in the future, I was shocked with the results. I definetly think if you're struggling with growing your hair out, breakage, and dryness this is for you, and yes you don't even need that much. I used half of what I normally use with other products. I'm very happy with the results as my hair was super manageable before even using the conditioner.

Rated 5 out of 5 by from Ahhh-mazing!!! Kerastase Resistance Bain Extensioniste Shampoo is truly remarkable at cleansing and adding strength to your tresses at the same time! After using this luxurious creamy shampoo my hair felt clean and strong rather than dry and stripped like most other shampoos I’ve tried! It is a mini spa treatment that smells like fresh botanicals being released from the concentrated creamy shampoo!! I massaged it in my scalp for about a minute to let it cleanse my scalp and take me away to an exotic island momentarily!! Followed by the fondue like conditioner you can say goodbye to bad hair days for good and hello to new lengths you never thought possible!! A+++!!! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Works Great! I Love It!!! I love the Kerastase Resistance Bain Extentioniste Shampoo for people seeking healthy strong hair. They smell of the shampoo is just perfect. Not too strong just right. Kerastase strengthens and fortifies your hair for reduced breakage. It brings your hair back to its healthy state, making your hair look wonderful. I loved the way my hair was smooth, silky, shiny, and it made me feel beautiful. I love how this product just made me feel great inside and out. It not only made my hair wonderful but made me feel pretty again. I really think you would love how your hair feels! Give it a try. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Great for summer hair I think I love the smell the most about this product- is that a bad thing? I have naturally curly hair & have to watch which type of products I use. My hair felt amazing while washing, but as it dried the ends were drier than normal. I'm not sure I could justify the price knowing that I wasn't in love with how it worked.
