Don't just wait for split ends to show up and then take action. When you use Sérum Extentioniste Scalp & Hair Serum, you'll be able to reduce the appearance of split ends as they grow, since this leave-in treatment helps hair at the root. Apply this to damaged hair to ensure the new strands that grow are as strong as possible.

How to Use
Use once or twice a week. Can be used on dry hair or after the shampoo and conditioner (sold separately) on damp hair. Apply 2 or 3 drops along all the scalp. Using the finger tips, work the serum into the scalp using circular motions. Do not rinse.

Ingredients List
CREATINE R COMPLEX , CERAMIDES

Rated 5 out of 5 by from Seeing Results in Length and Health I have used this product since Sep 2020 (2 vials so far), and am about to purchase my third in Jan 2020. I have thick, naturally curly hair which is cut in layers/highlighted every 8 weeks, and I typically blow dry straight with a round brush. I have seen improvement in overall health and shine, and recently, have seen exceptional increase in growth. I wash my hair with the extentioniste shampoo, towel dry, apply the extentioniste masque, and most recently steam my hair while using my facial steamer (10-15 min), massaging the hair and scalp. I then rinse, towel dry, apply the extentioniste serum, massage in, and then apply the extentioniste thermique (I may or may not blow dry at this point). This seems extensive, but I have noticed by doing this routine, I now only have to wash my hair (and do the process) on Sundays and Wednesdays, without any need for dry shampoo. 2020 was enough to make me realize this investment in myself is truly worth it—and is actually cheaper than the years of neglect and throwing fixes at my neglected hair (expecting miracles of my stylist every 8 weeks). I look great year round, and am protecting the investment I make every time I go to my stylist. This is the longest review I have ever written.
