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 5 out of 5 by from Just what I needed! I'm on my second bottle of this wonderful stuff!!! First off it smells heavenly. I wish I could find a perfume that smells like this. I have mid 40 color treated hair that is thinning and just plain blah. Since using this serum my hair loss is almost non existent. I used to find a clump of hair in the shower drain every time I washed, no more!!! I will NEVER go without this product. My hair is shiny bouncy and feels so soft. I use everything kerastase and I love it! Again the smell of this serum is INCREDIBLE!!! I highly recommend this product. The bottle lasts quite a long time too.

    Rated 5 out of 5 by from Absolutely great! This is my second time using this and I can see my thin , blonde, highly processed hair coming back to life! I can only say that I finally found the product and the line that I will always use from now on! Simply saved my hair! My hairstylist was so happy when he saw me with this nice , healthy looking, soft to touch hair! It gives not only shine and body but it feels so good to touch and it looks great! I use this in combination with the oleo serum. The only downside for me is that the bottle seems very big but is so little product inside! And I am only using 3-4 pumps.!!

    Rated 5 out of 5 by from Amazing! At first this product seemed like a gimmick to me. I've used several other scalp serums in the past to help strengthen my hair and help it grow and have had some slight success. I decided to try Initialiste after I found some impressive before and after picture of people who had used for 30 days.I am so glad I decided to try it!! I have been using it every time I wash my hair for a few months now. I apply 4 pipettes to wet hair in sections after towel drying, and then massage it into my scalp and run the leftover through the lengths of my hair. I can definitely see a noticeable improvement in my hair! It has been growing faster and is healthier, shinier and stronger. It smells great too. I will definitely keep using it!

    Rated 5 out of 5 by from Awesome to the nth degree!! This product is wonderful. I am a very active 52yo gym monkey. I noticed my hair thinning a bit on top so I started using this. I'm on my 2nd bottle now. It makes new growth begin and smells very good. I suggest to YouTube instructions on how to apply. Very helpful. You will not regret this purchase!!

    Rated 5 out of 5 by from Kerastase..nothing compares.. This product is amazing. It not only lives up to its standards but the results for me were outstanding. I had noticed for sometime since I had been going through hormonal changes that I was losing more hair so I decided to give Initialiste a try. Well to sum it up as usual within 5 treatments I already could see a drastic change in the hair loss as well as the thickness returning. All I have to say is if it wasn't for Kerastase my life would be in shambles.

    Rated 3 out of 5 by from Confused. Confused. Is this supposed to be better than the Resistance Ciment? Or the new Resistance Thérapiste? It seems like they all do the same thing? Can someone clue me in -- in all seriousness. I'm eager to learn and interested. The brand changes at Kerastase and constant influx of new products don't come with sufficient consumer education and clear points of difference.

    Rated 4 out of 5 by from There's life for your hair pos chemical treatment This product really works. I've been using it almost every day for the past couple weeks and I can feel and see the difference. My hair looks shinier, less frizzy with more "body". I have long hair, so the serum did very little to nothing to the ends of my hair, but on top of my head it looks much ticker. Even the texture of my hair looks stronger. The serum smells nice and it's easy to apply. I only wish this product was coming on a bigger bottle so I could use it in the whole length of my hair to see if it would make the tips stronger as well.

    Rated 5 out of 5 by from Gives Hair New Life, Bounce, Body I am on my second bottle of this product, and it really makes my fine, lifeless, highlighted, slightly damaged hair, have more body and it feel healthy again. I use less product than the directions advise, but I still get amazing results, The quality of my fine hair has changed - it actually feels thicker, bouncier, and more swishy! Also, I feel like I have to wash my hair less often, and that it actually holds my style in between shampoos better. Also, I have a very dry scalp. Ever since I have been using this product, and massaging it into my scalp, my scalp is MUCH more hydrated and less tight/flaky. So there are a lot of benefits from this one product - the quality of both my hair and scalp has improved drastically, I don't have to wash my hair as often, and it helps hold the style in between washing! The smell is lightly floral and pleasant, too. Give it a try!
