Review: Hair goals 100 - Great product! This hair serum smells amazing, feels lightweight, and has definitely reduced my hair fall. My hair feels stronger, smoother, and healthier without being greasy. Really impressed with the results and will definitely be purchasing again even though its pricey it lasts along time.
Review: My magic bullet - My starting point: - long-term commitment to Kerastase - I guess that’s why I’ve seen no ads and basically stumbled upon this serum during regular eyeballing of Kerastase catalogue. So I didn’t get any hype - I’m 31F with slightly highlighted fine blond hair and reactive scalp, that is healthy in remission and flaky/oily during flare-ups - after losing a lot of weight and a terrible long flu with 2 courses of antibiotics, I went into telogenic phase. I had my hands full of hair after every wash and actually had to unblock the drain. My scalp was itchy and flaky, my lengths were damaged and electrostatic, roots wouldn’t keep volume for more than a day - I tried everything: minoxidil, castor oil, scalp massage with a silicon brush, peelings, masks - you name it. It did slow the hair loss, but I still struggled Found this serum, and it’s day 10 of the course. Serum: - smell intensity: 8/10; some might find it very intense and I get it. For me it smells of an expensive aftershave and it doesn’t bother me much since I enjoy unisex perfume - texture: 10/10; thick serum that is very easy to measure and apply. You have enough time to distribute it before it goes dry, and the best part is that it actually doesn’t leave any residue and can even add a bit of volume. During first application I felt tingling for a short period - likely due to irritated scalp. Staring with second day, no more tingling - value for money: 10/10, but it’s tricky. If you apply it per instructions, one bottle will last about 2 weeks. That’s 1/3 of required 6 weeks, so you can easily multiply the cost by 3. At the same time, this serum turned out to be super efficient for me, and it very well justifies the cost. I’ve spent more time and money, trying other treatments - ease of application: 8/10. Instructions are clear, the applicator is sturdy and intuitive. It’s easy to measure and apply directly onto the scalp. You may need to adjust the quantity since the instruction says 3-4 doses (which is a lot) and if you are smart you can get it down to 2.5-3. Efficiency: I don’t usually review products halfway, but I’m so impressed with this serum already, so I couldn’t wait to share it. I notice no to very little hair fall. It’s even less than I normally have. Almost no hairfall during washing. My scalp went calm after the very first application and no more itching or flaking ever since. My hair holds volume. So overall I’m super impressed and this serum is exactly what I needed given my background

### ⭐⭐⭐⭐⭐ The best hair serum for hair loss
*by N***R on 6 December 2025*

This Kérastase Genesis Serum is hands-down the most luxurious way to treat thinning hair. Forget heavy, greasy scalp treatments—this is a lightweight, non-sticky gel that absorbs beautifully, giving my scalp a pleasant, cooling tingle right away. I noticed significantly less hair fall after just a few weeks of consistent use, especially when brushing and washing. The key is the powerful cocktail of Aminexil, Ginger Root, and Edelweiss Native Cells that fortify the hair fiber from the root. But let's be real: the divine scent is half the reason I look forward to applying it. It has that signature, sophisticated Kérastase fragrance—a bright, invigorating mix of woody citrus (like lime and bergamot) with a delicate hint of rose. It truly smells like you've just stepped out of a high-end salon, and the beautiful aroma lingers without being overpowering. It's pricey, but the ritual and results make it a 10/10 investment.
