I got a sample of Kérastase initialize cellulose vegetables natives Advanced Scalp & Hair Serum Concentrate for free from @influenster and I love it! I’ll definitely get another bottle of this serum because it made my hair feel good, shiny and moisturized. I’ll keep using it and I’ll edit my review as soon as I notice more changes in my hair. I read some reviews that say that it helped to grow the hair after using it so I hope it happens to me. It’s great for all types of hair. I applied 4 doses on my hair because my hair is thick but if you have fine hair you can apply 2 doses. It’s a leave-in product and you apply it after washing your hair and drying it with a towel. I’ll definitely get another bottle of this serum because it made my hair feel good, shiny and moisturized. I love Kerastase products so I really trust this product.  I like that it comes with the thing that gets the right amount of product that you need. It’s amazing and you won’t waste the product. It has 60ml 2.2fl.oz so you can take it with you when you go travel and the box has an explanation of how to use it in many different languages. I would definitely recommend it. It’s helping me to achieve my hair goals. Kérastase Initialiste Scalp & Hair Serum

I have purchased about six bottles of the Initialiste and it will always be a staple. I feel that it gives my hair shine and is a great primer before I use my leave-in.  I put it on my scalp as well as the lengths of my hair.

Initialiste is one of those products that, even though it is so expensive, I will always purchase it. One bottle lasts forever, and I can easily tell a difference in my hair and scalp when I use it compared to when I don’t.

Love this product. I just wanted something that would make my hair grow fast and stronger and this was recommended to me. This one jar will last you a year! My hair feel shinier, stronger, and has grown so much more.

My hair looked shinier and felt softer but it didn’t make it stronger. I’m struggling with hair that’s thinning and my main objective was for hair to grow trickier and stronger. If that’s your concern, try another product. Otherwise, it works well

I recommend this serum to all hair types! Scalp health is so important. This serum promotes thickness and hair growth and it really works! It is a little pricey but the bottle lasts a while depending on how much you use. I absolutely love it

OMG! I don't know how I lived so long without this. I have fine hair with an odd wave. This stuff makes it super shiny, soft, and manageable. Love running my fingers through it. And the smell...so good!

I started using this a week ago and I'm amazed by the result. I've had an issue with my hair breaking and thinning due to medication. This products is definitely working to help my problem areas and it's looking shinier and more voluminous. I'm hooked.

Has anyone tried this with the intention of hair growth? I find that my hair stops growing at it's current length, I just can't get it to grow any longer! I'm looking for something to stimulate growth.. Any ideas?

Does this actually work to grow out damaged hair (not start new growth, but make existing hair longer)? Is it worth the price?

Plain and simple - is it worth it? I have fine-average wavy hair but sensitive scalp due to bleaching and hard water.
