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 #KERASTASE94204 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 #KERASTASE100544 views - The user's roll: Lyko Creator.

Nice
I was a bit skeptical at first, but was actually pleasantly surprised by this serum. It feels light on the scalp and doesn’t weigh the hair down, while giving a fresh feeling. After a few weeks of use, I feel that my hair is stronger and that I lose less hair when brushing. The scent is also luxurious and makes the whole experience even better. It’s a bit expensive, but in my opinion worth it if you want to invest in stronger and healthier hair!1470 views - The post was made 1 weekRating: 5 out of 5verified customer
Satisfied!
Great! Incredible scent, already after a few weeks of use I notice that I don’t lose as much hair when, for example, showering or brushing my hair. I also think my hair quality has become softer.1068 views - The post was made 3 weeksRating: 4 out of 5verified customer
Good for hair growth!
#konkurranseinflutester I have now been using Kérastase Genesis Serum for quite some time, and I’m actually already on my second bottle – which says a lot about how satisfied I am 🤍 This is a product I have really seen good results with. I have especially noticed new hair growth at the temples, which is my biggest problem area. In my job, I have to keep my hair tightly styled with a lot of gel every single day, so it takes quite a toll on my hair over time. Therefore, it has been incredibly positive to see that this serum actually makes a difference! In addition, it smells absolutely wonderful, and the scent lasts a long time in the hair – which gives an extra feeling of fresh and well-groomed hair throughout the day. The reason I don’t give it full marks (4/5 ⭐️) is primarily the price. It’s quite an expensive product, and I notice I go through quite a bit since I have thick hair. Still, I feel it’s worth it – especially if you struggle with hair loss or want more volume and growth. All in all, a product I absolutely recommend!2752 views - The post was made 1 month
Extensions
Can this product be used on a head with tape extensions?4157 views- The user's roll: Customer service at Lyko. The comment was made 1 monthHello Julia!☺️ Yes, you can use it even if you have tape extensions 💛 The serum is applied to the scalp to strengthen hair and scalp, so it does not affect the tape bonds if you apply it carefully and avoid putting the product directly on the tape! Take care!1 likes

Works really well for me!
Super good product! I've used it for about half a year and have noticed that my hair has grown much better than before. I've long had the problem that my underhair grows but my transition hair just breaks off, which makes it look thin and damaged, but since I started using this, I've noticed that it has caught up and that the hair looks thicker and healthier. However, it is incredibly important to continue using it consistently, once a day on the scalp either morning or evening on dry or towel-dried hair, and since these are quite expensive, it quickly becomes costly, so you have to consider if it's worth it because you will need to keep using it if you want to maintain the results.3797 views
