Key Ingredients





How to Use

Apply Sérum Extentioniste directly to the scalp on cleansed, towel-dried hair.
Depending on hair type, 2 pipettes for fine hair and 4 for thick hair, position the pipette directly at the root and scalp to distribute 1 full pipette of the serum in a straight line from the front to the back of the head.
Follow the pipette with your fingers to massage the serum into the root and scalp as you work through each section.
Once application is complete in all sections, massage the entire head to distribute the serum evenly and comb through.
Leave in and proceed to blow dry.
Recommended to use at least 3 times a week.

Work the serum from your hairline to the back of your nape. Create a consistent routine for best results.

Rated 5 out of 5 by from This serum made my This serum made my hair grow so so fast, and helped it grow in thicker and healthier. Back in November, my hair was cut too much, to the point where it was barely touching my shoulders. Now, it's down to my armpits, in just 5 month's time. I highly recommend this product if you can afford it, especially alongside the rest of the Extensioniste range.

Rated 4 out of 5 by from This product works ... This product works ... but if you are on the fence between this one and the gold bottle ... get the gold bottle. The he scent is fresh and you will get results ... just be warned it takes about 3 months of nightly use before you really get your money’s worth out of it.

Rated 5 out of 5 by from I use this as I use this as a pair with the resistance kerastase cream. I can’t get over how good it smells. It is weightless so it doesn’t feel like I’m adding lots of product to my hair. My hair is also fine so I can’t use thicker product. It’s also a perk that it works to protect my hair from heat. I do style it a few days per week so it helps prevent breakage and split ends. Kerastase Resistance Ciment Thermique 5.1oz
