Difficult 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 #KERASTASE100602 views - Most helpful negativeThe user's roll: Lyko Creator.

As 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 #KERASTASE110423 views - The post was made 1 dayRating: 5 out of 5verified customer

✨ A truly luxurious serum for the scalp
This is one of those products that feels a bit extra luxurious to use. I really like the whole feeling around it – from the beautiful bottle and dropper to the actual application. It almost feels like skincare, but for the scalp. 🤍 I usually section my hair and apply the serum directly to the scalp. The dropper actually makes it quite easy to get the product exactly where I want it, and then I gently massage it in with my fingertips. What I appreciate most is that the serum feels light on the scalp. I was a bit worried that my hair would feel greasy or heavy afterward, but for me, it actually feels very pleasant. I also like that I can use it without needing to wash it out afterward. The feeling after application is fresh and cared for, and I really enjoy having it as a small part of my evening routine. It almost becomes a little self-care moment for the hair. 🥰 When it comes to the actual results, though, I think you need a bit of patience. This isn’t a product where I would expect a dramatic change after just a few uses. I see it more as a treatment that needs to be used regularly and given time. I also really like that the formula doesn’t feel heavy. For a scalp serum, that’s a big plus for me since I don’t want to feel like I have to wash my hair right after using it. A really lovely and luxurious product that makes the hair care routine a bit more thoughtful. 💆♀️✨795 views - The post was made 3 daysRating: 3 out of 5verified customer
Strong smell
I just started using this so I can’t tell if it works or not yet but why does the scent have to be so strong? It smells like straight up perfume and I can still smell it on my head hours after I put it on even though I only used a tiny bit on my hairline to test it out. If I leave the bottle open will it smell less?1 product in post Strong smell977 views - The post was made 4 daysRating: 4 out of 5verified customer
Works but way too expensive 🥹
Love this serum from the Genesis line by Kerastase. Has helped me a lot with hair loss due to medication. Unfortunately, it gets very expensive in the long run, so it’s not worth buying every time you run out.. You might as well buy minoxidil at the pharmacy. If the price were a bit cheaper, I would buy it more often ❤️🩹1054 views - The post was made 5 days
Product suitability
Hi, I would like to confirm if the product is safe to use while breastfeeding? Thank you 😊503 views- The user's roll: Customer service at Lyko. The comment was made 2 daysHi Emmi! 😊 I have looked into the product more closely. Kérastase does not provide a specific warning about use during breastfeeding, but they also do not have an explicit recommendation that the product is safe to use while breastfeeding. I would recommend asking your midwife if this is safe 🤗 Have a wonderful day!1 likes

pretty okay
I think this product is good, but I thought I would see more results than I did. Used up the whole bottle and felt like I lost a little less hair, but very expensive product for that result! A plus is that it smells really good, I think!1 product in post pretty okay1422 views - The post was made 1 weekRating: 5 out of 5

Expensive but does the job
It is expensive, hence 3 stars because you need to keep using it when it runs out and it gets costly in the long run, but it works well1515 views - The post was made 3 weeksRating: 5 out of 5verified customer
