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 #KERASTASE96805 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 #KERASTASE104374 views - The user's roll: Lyko Creator.

In love with the Genesis serum
A product I've grown fond of using. It fits well into my hair care routine, and my hair feels even stronger. I struggled a lot with hair loss due to illness, and now my hair is much better. It has also started to grow more hair in places where there was none❣️ I'm on my 4th bottle of Genesis serum💗 I find it practical that I can use the serum on wet and towel-dried hair😍 The only downside is that the product is quite expensive if you want to use it regularly. A little tip could be to use it every day either morning or evening for 6 weeks and then maintain 2-3 times a week. Here is my routine with the Genesis serum: 1 Use 4 doses (up to the black line) 2 Apply the serum directly to the scalp, not the lengths 3 Then I massage it in for about 3 minutes 4 And then I'm done ❣️ #lykoreview410 views - The post was made 3 daysRating: 4 out of 5
Smells strong
Smells strong. Hope I get back the hair I lost due to stress. Haven't used it long enough to give a fair judgment. Kerqstase is a good brand for hair!1 product in post Smells strong1233 views - The post was made 1 weekRating: 3 out of 5verified customer
Expensive
It's a good serum but a bit too expensive, there might be a growth scalp serum with the same ingredients that is cheaper2544 views - The post was made 2 weeksRating: 3 out of 5verified customer
Hair growth
Makes hair grow super fast and you lose very little hair when using this. However, if you forget to use it for a day, you lose a lot of hair again, so one bottle runs out quickly.1811 views - The post was made 2 weeks
Number of pipettes
How many pipettes should be used at a time? The description here says 4, but the packaging says 10.1 product in post Number of pipettes1670 views- The user's roll: Lyko Creator. The comment was made 2 weeksHi Axet! 👋🏼😊 Good question 😊 For the travel pack, the guideline is about 10 droppers at a time to evenly cover the entire scalp. The most important thing is to adjust according to your own scalp and where you want to focus the treatment. Use as many droppers as needed to feel evenly distributed on your scalp 🩷 Have a nice day ☀️

Scalp Care
I’m on my third bottle of this serum for the scalp. Sometimes I think we forget to care for it as well. We are often very careful with the skin on our face, but I think the scalp and face are connected. I started using it during the coldest winter because I had an incredible itch on my scalp. I wash my hair more often than is good because I sweat a lot from the waist up. It’s so much that my hair gets wet. It’s due to age and medication. Every night before I go to bed, I massage it in, and since I started, my scalp feels so much better. I very rarely get itching nowadays. I’ve also been quite harsh on my hair with bleaching and coloring, so I think both my hair and scalp need care. Also, I love the scent of the serum, though I know many think it smells too strong, but not me. What brings the score down is that it’s insanely expensive and not very economical. But it’s a fantastic product in itself. 🌸2344 views - The user's roll: Lyko Creator. The post was made 3 weeksRating: 5 out of 5
Magic
This product has greatly reduced my hair loss. Went from losing hair with every shower and combing to no hair loss at all. I use the product every morning. When used in the morning, it contributes to a refreshed feeling in the hair.2264 views - The user's roll: Lyko Creator. The post was made 4 weeksRating: 4 out of 5verified customer
Light and fresh feeling on the scalp, but requires patience
The serum feels cool and pleasant upon application and gives a fresher, more balanced scalp already after a few uses. The formula is light and non-sticky, making it easy to use daily. However, the results come slowly, so it requires a bit of patience — but the experience is luxurious and feels like a good investment to strengthen the hair over time.2550 views - The post was made 1 monthRating: 5 out of 5verified customer
Really satisfied!
I have been using the serum for exactly one month now, and I first bought a 30ml to test, and it lasted exactly one month. I am surprised at how good the results are. However, I have done scalp massage every day for 5-10 minutes when applying the serum to the scalp, but I see an incredible amount of small hairs that I have never seen or had before. Whether these are new hairs or my “old” hairs that no longer break, I can’t say. But the serum definitely does something! I am losing significantly less hair, and as I said, I notice a difference in the amount of hair since I suddenly have lots of small hairs everywhere. I would absolutely recommend it. I will continue to buy again and again ☺️ I like the scent, it might be considered a bit strong, but I like waking up in the morning and still smelling it because it smells good.1907 views - The post was made 1 monthRating: 5 out of 5verified customer
10/10!!!
Doesn't make the hair greasy at all, which I was afraid of. Have gotten much fresher and smoother hair. It's no longer dry and is growing. Really recommend!1835 views
