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 #KERASTASE

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 #KERASTASE

I have used this serum for several years in cycles when I get bald spots lost from hair due to my psoriasis. After 3 months of use on these areas, you can always see a significant difference in the area where the hair grows back again, as well as faster.

Comparison
Would you recommend this or Nioxin anti hair loss serum? What is the difference between the products and which is the most effective? ☺️

How long should you use the product?
It says to use it daily for six weeks (that's how long the bottle lasts too). But what do you do after that? Do you continue with a new bottle right away? Do you take a break and do a new application later? How long should you wait in that case? Or is the idea that you always start a new 6 weeks as soon as a bottle is empty?

  Hey again! 🥰 As mentioned, you can continue with the Genesis serum, for example 2–3 times a week, to maintain the results 🤗 Another good option for maintenance is the Kérastase Sérum Extentioniste 👉🏼 lyko.com/sv/kerastase/kerastase-resistanceserum-extensioniste It strengthens the hair in the lengths and keeps it healthy. Both work excellently, so it mostly comes down to a matter of taste if you want to focus on the scalp or the lengths 💕

Genesis Serum Anti Chute Fortifiant 90 ml
I had the honor of becoming #lykotestpilot and have been able to test Genesis Serum Anti Chute Fortifiant 90 ml for four weeks, and here is my experience. ✨ ❤️ Pros: - The packaging – Easy to use and dispenses just the right amount of serum. It is also well-sealed, which reduces the risk of spills. - The consistency – Light and pleasant formula that absorbs quickly into the scalp without leaving a greasy feeling. 💔 Cons: - Fragrance – Contains fragrance, which can be bothersome for those who prefer unscented products. - The scent – I find the scent to be quite strong and more on the masculine side. Conclusion: In summary, the serum did not quite live up to my expectations. The scent was too intense for my taste, and I did not notice any significant difference in hair loss during the testing period. One positive thing is that the bottle lasts a long time – after a month, there is still plenty of product left. Unfortunately, this is not something I would buy again or recommend, as I had hoped for more noticeable results. #lykotestpilot #kerastase

  Hey Amy! 👋🏼 A bottle lasts about 6 weeks with daily use, but depending on the amount and hair length, it may run out a bit faster 🩷 The recommendation is to use the serum as a treatment for 6–8 weeks to achieve the best results. When the bottle is empty, you continue with a new one until the treatment is finished. After finishing the treatment, you can either take a break and see how your hair feels, or continue with a new treatment right away - especially if you are still experiencing hair loss or want to prevent further. Many choose to do 2–3 treatments per year or during periods when the hair is extra stressed (e.g., during seasonal changes, after pregnancy, or a lot of stress). Remember that all hair is different and needs different lengths of treatments, some see results after 3 weeks and others after 9 📆 For the best results, it is recommended to use the entire Genesis series! Take care! 🌞

Test Pilot
I have had the honor of being a test pilot for #kerastase 🌸 I have fine, thin hair that is damaged from daily use of a flat iron. Serum: The serum is the best I have tested. I have hardly lost any hair and it smells really good. But it is not very economical, I have used up a bottle in 4 weeks. Hence the low rating. I probably won't buy it again due to the price. But I would really recommend the serum to anyone who wants to spend money on this.☺️ I am really so grateful to have been able to test the products #kerastase #lykotestpilot 🌸☺️

Unfortunately not the right match for my hair
I got to test this product as part of the Lyko Test Pilot program, in exchange for an honest review❤️ First impression: The bottle feels luxurious and of good quality since it is made of glass. Large bottle. Experience: I have used the serum according to the instructions, but for me, it feels a bit drying. After application, it leaves an alcohol-like scent on my fingers that reminds me of dish soap. My hair type: My hair is damaged, porous, and dry at the ends. I wash my hair about once a week to avoid further damage. Result: Unfortunately, I have not noticed any improvement regarding hair loss or hair quality. It may be that you need to use it for a couple of months before you see and feel an effect. Pros: • Glass bottle that feels luxurious • Easy to dose with a dropper • Can be used on both freshly washed wet hair and dry hair Cons: • Feels drying • Leaves an alcohol scent on fingers • No noticeable effect on hair loss #lykotestpilot #kerastase

  Hey Shiva 🩷 Thank you so much for sharing your experience with us! Kérastase Genesis Serum Fortifiant has a luxurious glass bottle and dropper that makes it easy to dose, but I understand that the bottle can feel heavy and that the scent didn't suit you 😏 The serum is designed to strengthen and reduce hair loss caused by hair breakage during brushing. It contains ingredients like Aminexil, ginger, and caffeine, which together are supposed to provide stronger and healthier hair over time. For best results, it is recommended to be used daily for at least 6 weeks 🤗 I understand that you haven't noticed any improvement, and that's completely okay, all hair types react differently. Your feedback is valuable, thank you again for taking the time to review! 🥰

A nutrient-rich serum!
Product tester 👋🏻 Serum from Kerastase, which I have tested for the last 4-5 weeks along with shampoo and conditioner also in the Genesis series. My assessment🌟 ⭐️ A light serum with a good and fresh citrus scent ⭐️ Easy to apply via pipette, and it settles nicely in the hair without giving a greasy appearance (something I often experience with hair oil) ⭐️ Overall, together with shampoo and conditioner in the same series, they complement each other very well and the hair feels shiny, strong, and light ➖ A bit pricey, even though there is a lot of product in a bottle ➖ Not used daily as recommended but 2 x a week, so unsure if results can be achieved with just the serum ➖ Should be tested over a longer period and also without using Genesis shampoo and conditioner to see if the hair strengthens only with the serum My assessment is that the serum has been useful together with shampoo and conditioner in the same series, but I haven't tested hair serum before, so not much to compare with. But my hair has never felt softer, shinier, and so light, so I will give Kerastase a thumbs up from me! #lykotestpilot #kerastase #gensis #serum

A serum to trust!
First, I want to start by saying thank you to Lyko for letting me test this serum from #kerastase that #lykotestpilot ❤️ The serum is my ABSOLUTE favorite in the Genesis line and the product I don’t want to be without! The serum is incredibly light in consistency and absorbs quickly without weighing down the hair, which makes it perfect even for fine hair.🌸 It is specially formulated for weakened hair that is prone to hair loss due to broken hair strands – something I have personally struggled with, both due to breastfeeding hormones and wear on my hair from highlights. Since I started using it, I have really noticed a clear difference. After washing my hair with shampoo and conditioner, I massage the serum into towel-dried hair at the roots, and it feels both fresh and light, without leaving a sticky or heavy feeling✨ I also like that it becomes a little moment of self-care; the massage in the scalp feels both relaxing and beneficial. The result has been that my hair feels stronger at the roots and doesn’t break as easily as before. It also stays fresh and airy for a long time between washes. 🫧🌸 For me, who has typically Scandinavian thin fine hair, I have found the serum to be economical and it will last quite a while, which is a plus. However, if you have slightly thicker hair, I think this bottle might go fairly quickly. 💸 The design is sleek and gives an exclusive feel in the bathroom, and the scent is sophisticated and a bit more on the masculine side. For me, this is not just a product that delivers results, but also a lovely addition to my hair care routine that I will definitely continue to buy and use 🌸

Good serum✨
Kerastase hair serum! Strengthening serum from Kérastase for daily use, prevents hair loss and hair strands that break. The serum is enriched with an effective combination of aminexil, Edelweiss Native Cells, and ginger root, which makes the hair more resilient. I have been so lucky to try this hair serum. I have been using it for 3-4 weeks now, and that might be a bit short to see the full effect. The serum smells good and is easy to apply with the pipette. I apply the serum in the evening so that it can work overnight. The hair does not get greasy. I will continue with the serum for the recommended trial period of six to eight weeks to see the effect of this fantastic serum. I think the serum is somewhat insufficient as one bottle does not last longer than four weeks of use. The price is a bit steep, but if it works, it is worth every penny. #kerastase #lykotestpilot
