The post was made 1 yearsRating: 4 out of 5Verifierad testareDifficult to assess the effect after only 4 weeks of use..I received this exciting hair product for testing as #LYKOINFLUTESTER. This is a strengthening serum from Kérastase that, according to the product description, is supposed to prevent hair loss due to hair breaking. The serum has ingredients that are supposed to make the hair more resilient and minimize hair loss. The serum is supposed to strengthen and care for the naturally protective barrier in the scalp. The serum should be used once daily in the morning or before bedtime. You can apply up to 4 doses to a dry or towel-dried scalp, section by section. 1 dose = 1 pipette to the mark. The serum should be lightly massaged in and not rinsed out. I was super excited to test this serum since after three pregnancies (six years since the last) I have gotten thinning around the hairline on my forehead. Here, the hair grows extremely poorly, and the little that grows gets a maximum of 6 cm long. Exciting to see if this serum could help. I also generally have hair that never gets as long as I want because it breaks and splits easily. I otherwise have medium-length, Nordic, fine hair with slightly bleached ends - otherwise untreated. I’m starting to go gray (I’m 43 years old). These are my thoughts on the product after 3.5 weeks of use: ✅ Lovely container that looks good on the bathroom shelf ✅ Good pipette that makes application easy, doesn’t drip. ✅ The product doesn’t feel sticky on the hands afterwards (even though you should of course wash it off) ✅ The hair doesn’t feel greasy at all when used (I’ve used it in the evening) 🚨 Quite okay scent (but relatively strong). Smells a bit masculine ❌ The bottle is not very economical in use and the price is quite high. I applied 4 doses each time and used up the product in 4 weeks. ❌ No visible results after four weeks. Maybe you need to use it longer to see results (but now the bottle is empty…) I find it difficult to properly assess this product since I feel it should be used over a longer time frame to see any potential results. #LYKOINFLUTESTER #KERASTASE107532 views
- Most helpful negativeThe user's roll: Lyko Creator. The post was made 1 yearsRating: 2 out of 5Verifierad testareNjaAs an influencer, I had the honor of testing this product. The packaging: In glass that feels sleek and luxurious with a smart pipette. So pretty with the ombre colors too. The consistency is gel-like and wonderfully cooling. Good consistency as it doesn't run out so easily 👌. It smells so good, both orange/citrus and a bit of woody undertone yum. Very fresh scent. I feel that the scent settles after a while, which I think is good since I have worked in healthcare. Smells mild but not too strong after a few hours. The pipette has a good clear marking for how much to take and is easy to handle 👌. When I apply the serum, I feel fresh. But my hair gets greasy, and I find it stiff/chunky after it dries. I don't like that it gives me such a greasy impression, something I really work to avoid. Even the next day, I find my hair greasier and with a strange slightly stiffer feeling in my hair. Which I don't like. I've been using it for a while now and notice no significant difference in my hair at all. I assume you need to use it longer. But I'm most irritated that my hair feels so greasy after a while within 1 hour of application for me unfortunately. So I think it's a ridiculously expensive product to give me greasier hair and no difference in hair quality, but I assume you need to use it for more than 2 weeks. I'm not that impressed yet, but I get to test it a bit longer to see if it gets better going forward. But I don't like the feeling in my hair after it has been a while. In the beginning, it feels super fresh and good, which then turns into a greasy strange feeling in the hair🙈. #LYKOINFLUTESTER #KERASTASE121069 views

- The post was made 1 weekRating: 2 out of 5verified customerSmells way too strongIf you're used to a bit more natural skin/hair care, the strong scent in this product will be too much. I'm not overly sensitive to perfume but won't be able to use this.1880 views
- The post was made 2 weeksRating: 4 out of 5verified customerSatisfiedI have never been so satisfied with a hair product. I have been using it since February and still use it. I recommend it, as this is the only thing that has helped me. - Gave -1 star due to excessive prices. (Small amount, excessive price.)2794 views
- The user's roll: Lyko Creator. The post was made 2 weeksRating: 3 out of 5Lovely product ❣️I am a bit divided when it comes to this product. • Do I like it? Yes • Will I buy it again? Yes • Can I live without it? Also yes That said, I love the scent of the product (some find it very strong). I think it’s an important step in the hair routine and I feel that my hair feels fuller and stays fresher with it. However, I can’t say that I see clear increased hair growth, which might be why many want to buy it. So it’s a lovely product that I will repurchase, the packaging is nice, and it makes a difference to the hair. The downside is that it might not fulfill the function you expect and it costs quite a bit! So if you want to try it and have some money to spare, go for it! ❣️ #lykomission #lykocreator #keraste3041 views

- The post was made 3 weeksRating: 4 out of 5verified customerWorks with continuous useI have used this product on and off for about a year. I really think it works, and I get a lot of new baby hairs where I have focused on applying the product. BUT, the effect is only there when you use the product and disappears quickly if you take a break. If you want lasting results, you need to use the product continuously, and it can quickly become an expensive expense since the product is quite costly and gets used up fast..2739 views

- The post was made 3 weeksRating: 2 out of 5verified customerHiThe serum has a very strong perfume scent. It gives me a headache when I use it. I also feel that my scalp becomes extra dry, possibly due to the strong perfume scent that the product contains.1991 views
