The Kérastase Bain Extentioniste shampoo is packaged in a beautiful see-through green blue hard bottle, a color that is used for all of the Kérastase Extentioniste products.
The top is a very elegant two-coloured hard cap, green blue and silver on top, where the bottle opens. To apply product, you need to turn the bottle head down and squeeze. On the front of the bottle, you’ll find the name of the brand, the name of the product, and some of the benefits of the shampoo. On the back as usual, you can find the ingredients and the application advice. It is quite large so not very practical for travelling, but it’s pretty enough to stand proudly on your shelf.
This shampoo is designed for slow growing hair with damaged lengths.
The shampoo has a regular creamy texture.
The Bain Extentioniste smells delicious and the scent lingers on your hair, leaving you feeling fresh all day.
Apply an amount the size of a quarter (not more!) of the Bain Extentioniste shampoo to wet hair. Massage through lengths and ends until lathered and then rinse thoroughly.
Kérastase markets this shampoo for its length strengthening capabilities. It is designed to boost strong hair growth starting at the roots. It contains a fusion of Creatine and Ceramides with Taurine, an amino acid with a protective effect on the hair fibre to help ensure visibly healthy and stimulated scalp environment.
The brand also claims that the shampoo is able to lift away the build-up of dirt, impurities and excess oil from the scalp.
We found that the shampoo was efficient in terms of nursing back damaged hair to life and emphasizing its growth. And if your hair suffered due to excess coloring, the Bain Extentioniste will help to get damaged locks back on track and your scalp will feel much healthier.
The period of use needed before there is a notable change varies from person to person and depends on how damaged and weak the hair is before use. We believe it takes in average about 2 weeks of use before really noticing a change, especially in term of hair growth. Ideal treatment length is 3 months, with the corresponding conditioner, for a full effect.
The Bain Extentioniste by Kérastase is priced at 26.9$ for 250ml.
