    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

    Nja

    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

    Kerastase genesis serum

    I have fine Nordic hair and have been testing this for several months now. It took a while before I noticed a difference. But eventually, I lost less hair and had fewer broken hair strands. I stopped using it for a little while, and then the hair loss increased again. I think it smells good, and my hair doesn't get greasy/dirty. The downside is that it's expensive.

    Hair loss that has gotten better 🫶🏽

    I have been using this serum since April 🌸I bought this because I had both lost hair and my hair had broken, which I know comes from previous stress. I feel that the hair loss when brushing and showering has decreased, which is probably due to several things, but I am sure that this serum has contributed 🫶🏽My scalp feels more balanced and fresh. It was quite dry before. The product is easy to apply with the dropper and does not feel sticky or greasy 👏🏻The scent is mild and luxurious – typically Kérastase – and the bottle feels exclusive. I use this after showering on towel-dried hair. It has lasted a long time as I wash my hair about 2 times a week🧴 Perfect for you if you have problems with temporary hair loss or stressed hair. I will definitely continue to use it🫶🏽

    Question

    Can you use this product even if you don't have hair loss, but just want to stimulate hair growth?

      Hey Tilda 🌸👋🏻 Yes, you can absolutely use it even if you don't have hair loss! 🙌 The serum is designed to strengthen the hair from the root and prevent it from falling out, but it also works great if you just want to stimulate the scalp and promote stronger hair growth. Perfect if you want to give your hair a little extra love and prevent future wear and tear 💆‍♀️💖 Have a really nice midsummer 💫🌻

    Breastfeeding

    Can this be used while I’m breastfeeding, or could it be dangerous for the baby? It smells quite strong too.

      Hello Birgitte 💕 Kérastase Genesis Serum Anti-Chute Fortifiant is not recommended during pregnancy. However, it is considered safe during breastfeeding. Still, we always recommend consulting with a doctor or midwife before use. Wishing you a nice day ahead 💌

    Good

    I tried the product according to the instructions for 6 weeks daily and then a few times a week. I don't believe that the hair will start growing faster than normal. However, the product provides lovely moisture to the scalp. The scent is nice, but strong. The scent does fade over time.

    Too strong scent

    I bought this at the end of April and have tried to use it 2 times on freshly washed hair and 2 times on dry hair, but it is so strongly scented that I can't stand it. Impossible to say if it's good since it has just been sitting in the cabinet. The scent worked somewhat better when the hair was freshly washed, but the product is really over-perfumed with a rather "masculine scent" that doesn't smell fresh, so I wish I had smelled it before I ordered. Such a shame for such an expensive product from an otherwise good brand.

    Hey

    I've been using this for a week now and haven't noticed any results so I'm wondering when I can start seeing results and if it's worth it
