Morning Routine

I’ve been using the Kérastase Initialiste serum for a few months now and honestly really like it. It’s super lightweight and doesn’t make my hair greasy, which is a big win. My hair feels softer and looks a bit shinier, and my scalp just feels healthier overall. It is kinda pricey, but you don’t need much each time so it lasts. I wouldn’t say it’s a miracle for growth, but it definitely helps with how my hair feels and manages day to day. Worth it if you’re looking to level up your routine a little.

Must Have!

I was super skeptical when my hair girl recommended I try this but now it's an absolute everyday must for me. My hair was thinning in the front and now it has filled in like never before. The texture of my hair is better than ever!!!

Originaly posted on  kerastase-usa.com

Love it! Makes me want to use it everyday!

Smells incredible! I have super fine 2b hair and I am on a journey of taking care of my new baby hairs that are sticking out so they can grow long. This serum is a great addition to my routine. I’m noticing less breakage of new hairs, overall softness and the formula doesn’t leave my scalp greasy at all. Hopefully will have more and stronger hair at the other side of my first bottle!

You Are going to Love Kérastase Initialiste Scalp

Kérastase Initialiste Scalp & Hair Serum and it has truly elevated my hair care routine. From the very first use, it feels incredibly lightweight and absorbs quickly into the scalp without leaving any greasy residue—which is a huge plus for me.

great for long hair

I’ve been using Initialiste regularly since 2014, and it’s my holy grail product. I have waist-length, oily hair, and this serum keeps it healthy while reducing breakage. I definitely notice a difference in my hair’s appearance when I stop using it for an extended period. It’s not a hair growth treatment like minoxidil, but if your hair is dry, frizzy, prone to static, or full of flyaways, this serum will help it look its best.

Restored my damaged, aged hair

My hair was so damaged, from over processing and color, that it was breaking off and falling out. I went back to my old hair stylist (who is rather pricey - which is why I tried someone new in the first place) and she cut my hair and had me buy this. I was shocked what a difference this serum made in just a few months. I’m happy to say my hair is growing back in and has stopped breaking off and falling out!

I’m not sure if this is working or if there are any benefits. If you need help with thinning hair go with the genesis serum instead.

Love the Product - Issue with Packaging

I really enjoy this product, however when I received it the dropper was broken. It looked like it had been cut in half when first pulled out of the bottle. I am still able to use it, but not to the same extent especially for the price.

Have not noticed a difference

Advanced scalp and hair serum that strengthens hair fibers and reduces hair breakage by restoring uniformity and smoothness. Loved this serum just feel like it finished way to fast.

Absolutely Blown Away!

[This review was collected as part of a promotion.] I don’t usually write reviews, but I had to for this product because I am seriously impressed. From the first use, I could tell a difference in how my hair felt. It was softer, smoother, and looked noticeably healthier. The shine it gives without making my hair greasy or heavy is unreal. What really surprised me is how lightweight it is. My hair still has movement and volume, but the frizz is completely under control. It also smells amazing without being overpowering. After using it consistently, I’ve noticed less breakage and my hair just looks more alive. It honestly feels like I walked out of a salon every time I style it now. If you’re on the fence — get it. This one is staying in my routine for good! 💁‍♀️✨ If you tell me the product name and what it specifically does (growth, repair, curl defining, etc.), I can tailor it to sound even more personal and detailed.

So far so good!

I haven’t been using this product for very long yet. The smell is amazing and I love the texture. It’s a little bit thicker than most of the other scalp serums. I haven’t really noticed any new hair growth, but I also haven’t been using this product for very long, but I do notice that it makes my hair feel a lot healthier and fuller.

Mixed feelings

[This review was collected as part of a promotion.] I’m on the fence about this one. Using this 2-3 times weekly and not really sure I’m seeing or feeling any benefits yet. For comparison, I’m using the Genesis system and serum (twice daily, except when I use Initialiste at night 2-3 times weekly) and I can feel and see a difference in my hair. Also, it’s a small bottle and the dropper only fills halfway - maybe this is how It’s supposed to be? Not sure if it’s worth the price.

Perfect for Fine, Thinning Hair!

[This review was collected as part of a promotion.] As someone with fine, thinning hair, I’m very picky about scalp products—and Initialiste exceeded my expectations. It doesn’t weigh my hair down, keeps my scalp feeling fresh, and over time I’ve noticed improved strength, shine, and less breakage. My hair feels healthier from the scalp down. I’ll definitely repurchase.

Lightweight and really works!!

[This review was collected as part of a promotion.] I am normally not one for serums because they tend to leave my hair VERY OILY. However, this one is so light weight and smells SO GOOD!! I love that it doesn't leave a residue on my hands either! I also love that it adds a bit of volume to my hair. I have very thin hair due to PCOS and this has helped quite a bit with added some volume back to my hair.

This serum has noticeably changed my hair in just 3 weeks! It has thickened my perimenopausal, thinning forehead/headband line. My hair is soft, it dries beautifully, not crunchy or oily. Makes my hair look healthier, more shine. I have fine thin hair. The only downside is you can't see through the bottle, so you can't tell when it's running low.

Great growth results!

I hit 40 and suddenly my hair seemed to be falling out and I had almost bald spots along my hairline. I was desperate to fix my thinning hair and blamed perimenopause. Several months later, my dermatologist confirmed I had a type of alopecia that is caused by traumatic events and made the hair stop growing. Long story short, this product was a huge help in getting my hair to regrow in the spots where it just stopped. I highly recommend it!
