How To Use
Apply Initialiste serum 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 blowdry. Recommended to use at least 3 times a week.

    Rated 4 out of 5 by from Stylist Says there is Growth While I can't really tell much difference, my stylist says she sees new growth since I've been using this product. I find the dropper does not pull nearly the amount of product out as in the "how to use" video. One bottle lasted 60 days using 3x week. I will order another bottle.

    Rated 5 out of 5 by from Secret to healthy, vibrant and long hair! Bought this about a month ago and there is a significant difference in the texture of my hair and the length. My hair has grown about 2 inches within the month I've been using it. love it so much! I'm ordering one for my sister because she kept wanting to shower at my house until I noticed she was using it! I was upset but I mean, who wouldn't be obsessed with this product so she ordered herself one (not going to share anymore lol) and I ordered another one for myself. However, this time I am keeping it locked in a make up case lol

    Rated 5 out of 5 by from This saved my forehead hairline! When I turned 75 my hairline, right in the middle of my forehead, began to recede and I turned to Kerastase products for help. The products that restored hair growth and had my hair looking soft, shiny and growing again (!) was Initialiste.
