Description

Discover Kerastase Masque Extentioniste, the intensive care mask that strengthens the hair structure and provides strength from root to tip. Ideal for long hair seeking vitality.

Strengthening from Root to Tip

The Kerastase Extentioniste range is the ultimate solution for those who desire long and healthy hair but face damage issues. Its specialized formula penetrates deep into the hair, strengthening its internal structure and helping it return to optimal condition. The product shields the cuticle, covering it evenly and providing long-lasting protection. It is the ideal care system for hair that suffers from daily stress, ensuring that every strand remains strong and resilient.

Clinically Proven Results

The results of using Extentioniste are impressive and visible from the very first applications. With systematic use, you achieve 99% less breakage and 78% fewer split ends, allowing your hair to reach the desired length without loss. In fact, studies show that you can gain up to 4 centimeters longer hair in just 3 months. Forget frequent visits to the hair salon for trimming damaged ends and enjoy the length you have always dreamed of.

Keratin and Ceramides Technology

The strength of the range is based on innovative technology that combines Keratin and Ceramides. These ingredients work synergistically to enhance hair resilience and restore its surface, making hair stronger and more elastic. Keratin helps protect the internal bonds, while ceramides seal the hair cuticles, offering softness and shine. The result is hair in excellent condition, full of vitality, able to withstand the challenges of styling and the environment.

Intensive Strengthening and Vitality

The Kerastase Masque Extentioniste mask is the ideal solution for those who desire healthy and strong long hair. Its advanced formula works inside the hair fiber, helping hair regain its lost vitality and natural strength. It guarantees an exceptionally shiny result that starts from the lengths and reaches the ends, ensuring that your hair looks and is healthier than ever. Additionally, it contributes to cleansing the scalp, creating the right environment for the growth of new hair.

    This product is amazing! Combined with the shampoo, from the first 2 applications they changed the feel of my hair!! They made it soft, smooth and most importantly, they repaired the ends which were severely damaged from highlights and bleaching! I couldn't believe it!! Also, even though I have oily skin and used it in June with a lot of heat, it didn't weigh my hair down at all! I highly recommend it!

  • I had bought the shampoo from the line, which excited me, so I got carried away and bought the mask as well. It didn't offer anything more than a regular supermarket hair mask. Also, when I applied it to my hair, it became very runny, like water. Overall, for the price, I think it's not worth it.

    Second package and I won't change it! Even in difficult moments due to bleaching, it made my damaged hair look much healthier, as if it "sticks-binds" the ends. It's worth the money but it's not for deep hydration!

    Makes hair shine. Helps with frizz and creates a glass-like shine filter on dry ends, softening them greatly. Hair that shines, is soft, and smells good! It's worth it, it's a very good mask!

    I have indeed bought the spray, the oil, the mask, the conditioner, and the restructuring shampoo, but all of these together, if you follow the instructions, work wonders. After the third application, they started to shine, detangle more easily, be elastic, and have volume. Plus, they smell wonderful. I am really enjoying my hair now. Of course, if you have damaged hair from dyeing, it's not worth getting any product, and no mask will help with hair damaged from bleaching. Only the hair salon can help in that case!

    After 1.5 months of use, I am very satisfied. The ends of my hair (blonde and damaged) have smoothed out, they look healthy and soft. Before I got it, my ends would become hard and wouldn't lay flat after washing the next day.

    I really understood why the products of KerasTaz cost so much. I bought the mask and the serum. I saw a great difference in the quality of my hair. And in the long run, I would choose them again.

    It leaves a very nice feeling on the hair, but the main promise it makes, 4 centimeters in three months, not at all! It should be noted that my hair is very, very short, I don't dye it and I don't stress it with styling products! So the three centimeters they gained, I would have gotten them anyway!
