Healthy Scalp

No change to hair

Smells good but has done nothing for my hair. Still experiencing the same amount of breakage and fallout from before use. The genesis serum worked so much better, will continue to buy that one instead

My scalp and hair is so healthy!

I have tried many scalp/hair serums and this is by far my favorite. I use it every 3 days after washing my hair (after my roots are somewhat dry) and it does not leave any residue or weird film on my hair and scalp like many other serums do. I have been using it a few months now and my roots have never grown out so fast. Definitely feel like it’s making my hair thicker too!

worth it

[This review was collected as part of a promotion.] My hairstylist recommended that I start using a scalp product because of the sweat from the gym and to keep my scalp really clean, and I’m loving this one! The smell is amazing—very fresh and fancy. I also use it with the scalp brush from Kérastase, which makes the experience even better. I’ve noticed my hair feels a little more oily than usual when I use it, but honestly that’s not a problem for me because the results are so worth it.

Didn’t Notice a Difference

I was excited to try this serum, but unfortunately I didn’t see much improvement in my hair or scalp after consistent use. It didn’t seem to add any noticeable strength or shine compared to the other products. For me, this one wasn’t worth the investment.

Very good product. I do combine it with the genesis hair serum and alternate between both of them. I enjoy them very much.

Great product, horrible packaging.

Absolutely love this product. It helped me grow my tension bald spot back in a little under 2 months. Minus one star because the dropper is god awful and I am quite literally begging Kerastase to change the packaging. I feel like I have to pump this thing 5 times to even get half of a dropper full and then repeat so that I can get a full dropper on my head when I do my routine. Idk if I got a dud or what but this thing frustrates me every time I go back into the bottle.

This serum really made a difference!

After the initial use of the Kerastase - Initialiste Scalp & Hair Serum I noted a noticeable improvement in the overall health of my scalp and hair at the base of my roots. I would definitely recommend this to anyone who has experienced flakiness around their crown and/or itching and dryness. It really has helped with the health of my hair and scalp in a relatively realistically reasonable amount of time. I am so happy with the results!

Little bottle of miracle serum

I have purchased this serum 3x now and it has absolutely saved my desert dry blonde hair ! I have natural blonde hair but I do get a few platinum highlights a few times a year and this serum has made my scalp and ends very happy . My hair feels soft. Is more manageable. As well as my scalp feels less desert air and sun dried out … I will purchase again ! Oh and it smell divine . Like I just left the spa . I recommend it to anyone that ask me about my hair health and my hairstylist now recommends it to all her blondes who’s ends looked terrible ! She even loves it for her hair as well ! Thats saying a lot because she is an expert colorist and blonde specialist. Give it a try ! I believe your scalp and hair will love it

Meh…

I ordered this to help with my hair shedding. The reviews from others seemed really positive so I took a chance on this particular serum. What I didn’t see mentioned in the reviews is the pimples and irritation this caused. I followed the directions and at first I thought it was just because I was getting used to it, but I’ve been using it now for a few weeks and I am not impressed. I *think* it was helping with less shedding BUT everywhere I put this on my scalp, I broke out with deep painful pimples. On my scalp and my hair line. Needless to say for the price I paid I’m a bit disappointed it clogged my pores enough to cause issues. I will definitely not be finishing the serum which just seems like such wasted money.

Turns frizzy fuzz into gorgeous locks

I have thin, color-processed hair that goes from frizzy to flat and greasy looking when I add most hair serums. After trying lots of alternative products, I have found that the Initialiste Scalp is the only one that provides the texture and shine I want, without weighing down my hair.
