Strengthening Long Hair Shampoo Kerastase Resistance Bain Extentioniste

Girls, I highly recommend this technique! First, thoroughly wash your hair and roots with other shampoos that remove all the dirt and make your hair squeaky clean during washing! Then, use this one, but try not to wash the roots with it, only the length. This way, you'll achieve a great effect and your hair won't get greasy throughout the day! I tried this technique to test it out, and it worked for me!

It might not have suited me, as my hair looks good after using it, but it tends to get oily faster. It foams well, but it's not very economical.

The shampoo didn't work for me. I have long, uncolored hair and a normal scalp, but with this shampoo, my roots became greasy faster, while the ends of my hair became even more dry. I wash my hair every other day, and on the day after washing, my roots are already stuck to my head, like a little cow licked them. Although overall, I have tried many products from this brand and they were all okay. My favorite product is the Kerastase pink Genesis spray, I adore it!

I have used it 2 or 3 times already, but I haven't seen any magic yet, so I'm not sure if it should be blamed. It smells nice and does its job well.

Great shampoo. Just what I needed! It cleanses superbly. I had to wash my hair daily, in the morning specifically, because if I wash it in the evening, it would be dirty by morning; now, I can go every other day, sometimes even every two days before the third. My 8-year-old daughter also loves it, her golden locks look like they're straight out of a salon. I, on the other hand, need to put in more effort.

Awful shampoo (from personal experience)

I recently had the unfortunate experience of trying out a shampoo that I can only describe as terrible. The product itself left me highly dissatisfied and disappointed.

First and foremost, the shampoo's performance was subpar. It failed to effectively clean my hair, leaving it feeling greasy and heavy. It lacked the ability to remove excess oil and dirt, which ultimately resulted in a lackluster appearance.

Furthermore, the scent of the shampoo was quite unpleasant. Instead of offering a refreshing and pleasant fragrance, it emitted an overpowering and artificial smell that lingered on my hair long after washing. This was not only bothersome to me, but also to those around me, as the fragrance was quite strong and intrusive.

Additionally, the shampoo did not provide the expected hydration and nourishment for my hair. Instead of leaving my locks feeling soft and moisturized, it had a drying effect, making them appear dull and lifeless. This was definitely not the result I was hoping for.

In terms of packaging, the design was lackluster and unappealing. The bottle itself was not user-friendly, making it difficult to dispense the product efficiently. This was a frustrating aspect, as it wasted both time and shampoo.

Overall, I cannot recommend this

In my case, this shampoo dries out my thin hair, making it stiff even after conditioning, and there is no shine. I am once again convinced that the Genesis series is the best.

I was very hesitant about buying this shampoo, but it is definitely worth the money. The shampoo is fantastic - my hair roots look "non-greasy" for several days, no itching on the scalp, it is economical to use, lathers well, and cleanses effectively. I am extremely satisfied!

I occasionally purchase this product along with the fondant from the same series, and everything is fine.

Another worthy product from Kerastase. This shampoo for long hair is of very high quality. It is transparent, lathers well, and effectively cleanses. It leaves the impression that it also slightly straightens the hair.

I have been using this shampoo for a long month now. Before that, I was using Ogx with argan oil (after which the quality of my hair was terrible). I decided to buy this shampoo and I use it together with the mask for weakened hair and the heat protectant from the same manufacturer. In a month, the quality of my hair and scalp has improved significantly! My hair is falling out less, dandruff has stopped, the hair itself has become softer, and there is a shine. Overall, this hair care routine is amazing, and it is definitely worth the money!

This line is pure love!
I don't even know how many times I've bought the shampoo + mask.
I have thick curly dyed hair - it suits me perfectly.
I highly recommend it!

Good day! This hair care system is absolutely amazing! I have long, thick, dry hair that I couldn't manage, and my scalp was excessively oily. Now, I can afford to wash my hair every 4 days, thanks to the mask and fountain, the texture of my hair has significantly improved. They have become smooth, bouncy, and shiny. Ladies, I genuinely share my review and thank you for this product.

I tried a sample of this product and it cleaned my hair well and gave it volume, so I decided to order the full-size version. However, after a couple of uses, it stopped cleansing my hair properly and left my scalp dirty. On the second day, my hair was a complete nightmare, all tangled and greasy. I've never experienced this with any other shampoo. It's just a waste of money.

In the trash. The unwashed hair effect.
On the second day, my roots became oily and looked untidy. I usually wash my hair every three days, but this is the first time I've experienced such an effect from a shampoo.

This shampoo is good. However, I preferred the previous series more. For very long hair, a conditioner is definitely necessary (otherwise, no way). One downside is that it stings the eyes.

This shampoo is just plain ordinary. It has absolutely no effect. It's not worth the money, unfortunately.

After using this shampoo, my hair feels voluminous and elastic. I am extremely satisfied with the outcome. I have oily roots, dry ends, and porous hair.

I have uncolored, dark, oily roots and dry ends of hair. I really liked this shampoo. My hair feels soft, smooth, and looks fresher and longer. Unlike when I use Davines Oi or Milk Shake, where my hair gets very greasy on the next day after washing, with this shampoo, I confidently go until the evening of the following day. It did not cause any allergic reactions. I wash my hair twice. I recommend it!)

The shampoo was perfect for oily scalp, leaving my roots voluminous and clean. The conditioner was sufficient enough to easily comb through wet hair without any issues. I noticed significantly less hair on the comb than usual. As a finishing touch, I used the heat protection from the same series. I am very satisfied with the result and the product. My hair is clean and soft.

I have fine, shoulder-length, highlighted hair that tends to become frizzy and fall out. My personal advice is not to follow the shampoo instructions - don't leave it on your hair, rinse it out almost immediately. The result is fantastic. My hair looks shiny, silky, and has more volume. It hardly gets frizzy, and there are very few hairs left on the comb. I'm extremely satisfied. I will consider trying the conditioner from the same line or the Discipline range.

Kérastase, as always, is on top of its game, and this shampoo is unparalleled. After trying a small bottle on my hair, I decided to get the larger packaging. I must warn you, it may not suit every hair type, but mine were quite satisfied. The scent is divine, and it delicately and easily cleanses the scalp. As a bonus, it promotes crazy hair growth. This size lasts me about six months with regular use three times a week. Combining this shampoo with the rest of the lineup will make your hair look salon-fresh. In conclusion, Kérastase is forever, and this shampoo, in particular, is a winner!

Unsatisfied, when will you finally remember that shampoo is intended solely for washing hair? Hair care products are sold separately! The shampoo is amazing!

The shampoo itself is good - it has a great smell and makes the hair softer. However, I didn't notice any effect in terms of strengthening the hair, unfortunately. I used it together with the Kerastase serum from the same line. Perhaps it's individual, and it's preferable to choose similar hair care products based on the recommendations of a cosmetologist. I've seen many people mention problems with dandruff after using it, but personally, I haven't experienced that. Of course, the ingredients list for this product is quite long, so there is a high probability that some components may not be suitable for the scalp.

The shampoo is excellent! Highly recommended!! I have thin, long hair and after using this shampoo along with the mask and serum, I noticed the effect after three washes. The shampoo was recommended to me by a specialist at the salon.

This shampoo is really good. It worked perfectly for me, and I have thin and porous hair.

This shampoo is really good. It leaves the hair smooth, but there is a slight dandruff issue.

In the salon, I was told that this shampoo was created as a replacement for Cristalliste, which has been discontinued. Since Cristalliste is my favorite shampoo, I decided to try this one. However, I am disappointed. The most unpleasant thing is that it weighs down my hair, and my scalp quickly becomes greasy. I don't feel clean after washing. With Cristalliste, I used to wash my hair every three days. But with this shampoo, my hair becomes greasy on the second day. In addition, my hair has lost its shine, probably due to poor cleansing. Maybe it does help with breakage, but what's the point of having long hair if it's constantly greasy and dull?
