GREAT SERUM!
[This review was collected as part of a promotion.] So I ended up only ordering this product only because the Genesis Serum was on backorder for a long time. I didn't have high hopes since I looked at it like a backup plan, but I was really impressed! This product really made my hair stronger! I could feel the fullness of my hair at the roots and the strength of new growth! I am now going to add this into my rotation!

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!

great hair serum
First time using it, the serum is not sticky as other brand serum. It did not make your hair stick together. really light serum. Also, I love the smell. It smells floral. I just try it for a week, together with the Genesis shampoo and conditioner. so far my hair falling less than last week. love it.

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.

I’ve been using this for about a year now along with some vitamins and my fallout has been significantly reduced. When I ran out of this, I noticed my fallout picked up again so I rushed by to place another order. It’s easy to use and lasts me several months. An added bonus is it smells nice and doesn’t weigh my hair down in the slightest.

Packaging and pipette terrible
Not sure how the serum is working yet, but the packaging is TERRIBLE. The pipette barely sucks up any serum, and you'll get more dripping off the side of it than in it. The bottle itself is top heavy and has fallen over several times. Pacifica scalp serum has more functional packaging and a more functional pipette. Will not be repurchasing until the packaging is more functional.

I’ve really noticed a difference. This serum is a game changer. The only thing I don’t like is that I can never tell when I’m about to run out so I always have a backup ready. But it’s worth it. It’s really helped with my hair loss. Highly Recommend.

Would Trade My Left and Right Sock for This Serum
[This review was collected as part of a promotion.] Listen, I don’t know what kind of sorcery the creators of this serum are practicing, but if they told me it was brewed under a full moon by a coven of radiant-haired forest witches, I’d believe them. Because this stuff? Transcendent. First of all, the aroma is so heavenly it practically deserves its own zodiac sign. One whiff and I was suddenly prancing through a field of lavender while someone named Fabio whispered compliments about my follicles. Now let’s talk performance. My hair was basically a haystack with commitment issues-dry, rebellious, and constantly threatening to jump ship. But after ONE WEEK of using this elixir of the gods, my strands are smoother than a jazz sax solo at midnight. Breakage? Mended. Frizz? Tamed. My scalp? Hydrated and feeling like it just came back from a 5-star spa retreat in the Alps. This serum doesn’t just soften hair-it ennobles it. It whispers to your roots, “You are worthy. You are moisturized. You are magnificent.” If you’re still reading this and haven’t added it to your cart, do you even care about your head? Because I do. And clearly, this serum does too.

Best hair care serum to incorporate in routine
[This review was collected as part of a promotion.] Kerastase Inialiste is a hair serum product that I swear by. I tell every one how this product has changed my hair for the better. I use it almost every other day and night right in the area of my scalp where my hair has broken off . I definitely recommend this product. I seen a change in a month and I’m sure the results are different in everyone. I went from crying every time that I washed my hair. To smiling every time I used initialiste . I’m so happy and content with this product. It’s a miracle worker. Hands down if you are having this struggle with hair fall around your hairline and down the middle of your scalp . These serum drops will work. It takes time bro work but when you see the results you won’t stop using this serum.

Difference noticed after a few uses.
[This review was collected as part of a promotion.] My job requires me to wear my hair in a tight bun everyday, which sometimes ends up being 12 days straight in a row. Even prior to this job, I've had issues with loss of hair due to a thyroid condition and now I am noticing a significant amount of breakage in my hair due to work regulations. This is just one of my tools I use from Kerastase to help with that. I used to wash my hair once every 5 to 7 days because it was that bad, now the more I wash it with Kerastase products, like this one, I am noticing a significant improvement. I only use then one when I wash my hair but it has really been a help in the breakage.

It smells nice
[This review was collected as part of a promotion.] This smells nice and doesn't leave the scalp oily or feeling like there is something there. I'm not sure of the results yet.

Not for me.
[This review was collected as part of a promotion.] For me personally every time I use it you can't even tell. It's expensive so I thought for sure this has got to work. But I'm super disappointed

Love the smell
I've only used it for a few weeks. It has a nice soft smell and is very light in texture. Glides on. I cannot comment yet on any other results. It's too soon.
