I received this product in exchange for my honest opinion. I’m a huge fan of Kerastase products, some of them becoming holy grails for me. However, after using the Longevity Potion, my feelings are mixed. It is a greatly quality product but I do not think it made such a difference on my scalp and overall hair health. As such, I think it is worth a try. Maybe long term use is the ideal way to use it in order to see results. But in my case, I don’t think I would purchase this again in the future.

[I received this product in exchange for my honest review] This does make my scalp feel hydrated and it smells sooo good! I don't know if it will improve fullness over time, but I hope so! I only rated it four stars because it does make my hair feel a bit greasy.
[I received this product in exchange for my honest review] Serum works beautifully on my hair. It protects against heat without leaving any heavy or greasy feeling. The texture is lightweight, and it makes my hair look smoother, shinier, and healthier after styling. I also love the clean, luxurious scent. If you use heat tools often, this is a great product to keep your hair protected and polished. My hair feels silky, smooth, and smells amazing every time I use it. It protects from heat without weighing it down. Totally worth it—Kérastase never disappoints! Love it! It keeps my hair shiny, smooth, and in place with a bit of bounce. I have shorter hair right now and use less than the quarter size recommended. It is worth the investment
[I received this product in exchange for my honest review] I have been using this product for a little over a month. I have fine hair and a lot of serums weigh down my hair, but not this one! First of all it smells divine and a little goes a long way. My hair looks and feels healthier! The shine is out of this world!
[I received this product in exchange for my honest review] I have been looking for a scalp serum to hep treat my dry, itchy scalp. This cute little bottle comes with a dropper and it’s convenient enough to put all over your scalp. Within the first few days it worked great. It had a very pleasant fragrance which made me want to use it even more. It wasn’t greasy, and my hair didn’t turn greasy even after several hours, in fact my kids asked me if I had recently gotten my hair done, they thought it looked nice. Great product, I recommend to anyone!
[I received this product in exchange for my honest review] I’ve been using this scalp serum for weeks now. It’s easy to dispense. It has a gentle scent. It’s not greasy and absorbs quickly. It doesn’t change the feel of my hair. Having said all that, I truly do not see any difference after using this. Maybe I need to use it for another month? Maybe that would show? I’m not sure but my hair looks good either way.
I have been using this for a month so far, and I do have less fall out. I apply it after I get out of the shower on damp hair…after I apply it my scalp feel a warm sensation. The smell is pretty good not to over powering. My hair is also less dry, I only apply to the scalp but I feel the difference from the top moving to the tips. I do have a wavy, frizzy hair so I do have to add product…but like I said big difference is less fall out! Picture is with no product!
[I received this product in exchange for my honest review] This works great to give your hair more volume! I wasn’t really sure if it would give such volume because it is this thin solution but whatever it does it is amazing!! I usually have sensitive skin but this was fine and didn’t bother me at all. The smell can be a bit much when you put it on but it becomes less potent as your hair dries. I usually have to put a cream in my hair to give it even a bit of volume but this works so well I don’t need it which makes my hair lighter and cleaner feeling but with volume.
[I received this product in exchange for my honest review] I really like the Kerastase scalp serum. It is a thin serum which makes it super easy to apply. It smells absolutely amazing and leaves a nice cooling effect on the scalp.
[I received this product in exchange for my honest review] I absolutely love this serum! I was beyond excited to test it out because I am struggling with thinning hair and breakage. I have been using it several times a week over a month now, and I have seen and felt a huge difference. My hair feels stronger, more hydrated and overall healthier. This couldn't have came at a better time. It doesn't leave any residue or leave your hair feeling greasy. After I apply it, I style my hair as usual. It also offers heat protection which is a huge plus. My hair isn't breaking off as much as it was before I started this serum. As you can tell in the pictures, my hair is also shinier and has more volume than it usually does. I cannot wait to see how it continues to improve my hair over the next few months. I already have tons of short baby hairs growing near my scalp, I am hopeful I will get my hair back to being healthy again.
