    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

    Had higher expectations

    I had very high expectations for this since I heard so many good things about it, but it made no difference to my hair. Maybe it requires that you have lost hair for it to activate already existing "hair follicles." For me, who just wanted more hair in my temples, unfortunately it gave no results. Smells good!

      Hi Elin! 😊 Thank you for sharing your experience! So typical that the product didn’t give the result you hoped for. The result can vary depending on the hair’s starting condition and regular use over time 🤍 Wishing you a nice day! 🌸

    Good serum🥰

    Have finished a bottle of the Kerastase Genesis serum now. I've noticed a bit of a difference with less hair fall, e.g. when I shower or brush my hair. I don't see any visible difference in the hair looking healthier and stronger, probably need to buy another bottle to see more difference there😅 Therefore, I give the serum 4/5 stars, with the possibility of 5 after testing another bottle😍👏🏻 #lykoreview #lykocreator #kerastase #haircare #genesis

    A staple favorite in my hair routine ✨

    I am now on my third bottle of this product, and I love it! It has truly become a staple part of my hair routine. It’s easy to use and can be applied to both dry and wet hair without the hair feeling greasy, sticky, or heavy. Additionally, it has an absolutely fantastic scent that makes the product feel luxurious. After using the product for a longer period, I think I can see and feel a difference. I have more baby hairs around my hairline, and I also notice that my hair breaks less than before. Overall, my hair feels stronger and healthier, and I think it looks fuller. All in all, I am very satisfied with the Kérastase Genesis Serum and can definitely recommend it 🤍 #konkurranseinflutester

    Genesis serum

    I love it! I have used 2 bottles and new hair has started to grow. Also, fewer hairs fall out when brushing. I have fine, thin hair. I use 2 pipettes every night. I also use Genesis shampoo and conditioner. My scalp feels better and I feel that the condition of my hair has started to improve. #lykoreview

    One of my favorite products for the evening hair routine!

    I started using this when my hair was damaged from bleaching and I just wanted to let it grow out to become stronger again. I repurchased this product twice because it gave great results and provides a luxurious feeling in the evening routine!

Genesis Anti Hair-Fall Fortifying Serum: Fuller-looking hair in 6 weeks*

The "Skincare-for-Scalp" Routine
Elevate your daily routine for hair that feels stronger and looks fuller. Genesis is a daily fortifying program specifically designed for weakened hair prone to falling out due to breakage.

Why It’s Different: Lightweight Science, No weigh-down
A high-performance serum that absorbs instantly without leaving a residue. Perfect for daily use on wet or dry hair without weighing it down.

The Power of Fortification Enriched with Aminexil, Ginger Root, and Caffeine, this formula is clinically proven to:
Help reduce hair-fall due to breakage*
Reinforce the hair fiber at the root*
Strengthen the scalp's natural moisture barrier***
Leave the scalp feeling refreshed and soothed**

Consistency is key - What to Expect on your 6-Week Journey
Weeks 1–2: The scalp feels refreshed and better hydrated**.
Weeks 3–5: Hair feels more resilient. You are building the foundation for reduced breakage (Maintain your daily application to keep the momentum).
Week 6+(Visible Results): Noticeably less hair in your brush and shower (due to reduced breakage), with hair that looks healthier and more voluminous*.

How to Use: Apply once daily. Use 4 pipettes section by section on the scalp, or target specific concern areas. Massage gently into the scalp to support absorption. Do not rinse.

Pro-Tip for Continued Resilience:
Keep the momentum going! To maintain a resilient scalp barrier, transition into a maintenance phase by applying the serum 2–3 times a week, just as you would use a high-quality serum in your skincare routine.

Track Your Progress:
Experience your own results. Documenting your 6-week routine with photos is a simple way to track your hair's resilience.
