    Super conditioner!

    I had the honor of testing this conditioner and the corresponding shampoo from #KERASTASE. I was very happy about that since I have tried some from the brand before and really like their products🤩 Maybe about 10 years ago I bought my first product from Kerastase, and I will always continue. This conditioner I think softens and detangles the hair super well. Feels almost like a hair mask. The product line Genesis, to which this conditioner belongs, is a series of products that are supposed to be good for hair loss and broken hair strands. I have noticed a bit of hair loss lately. The conditioner cares for the hair strands and ensures that they do not break. I think the hair both feels and looks healthier, fresher, and shinier after I have used this conditioner (together with the corresponding shampoo) I love the packaging, and pink is my favorite color, so the products are really super pretty🌸😍 Luxurious value! However, the caps are a bit clunky to screw on when you're standing there in the shower wet and slippery💦 Overall, I think Kerastase has really nice and luxurious scents in their products, though quite strong. I, who am a bit sensitive to certain scents, have a bit of trouble with this scent. But I find that it varies from day to day how sensitive I am and how much I can smell this scent. But I love to smell good and freshly showered for a long time! 🤧 So overall a really great product, and I'm very happy that I got to test as a #LYKOTESTPILOT 🤩

    Genesis Fondant Renforcateur conditioner 200ml

    I had the honor of becoming #lykotestpilot and have been able to test the Genesis Fondant Renforcateur conditioner 200ml for four weeks 🩷 ❤️ Pros: - Convenient packaging – easy to squeeze out the right amount and no issues with leakage. - Light formula – the conditioner spreads easily in the hair and you don’t need to use much for it to last. 💔 Cons: - Perfume – contains perfume, and for me, the scent was noticeable. - Character of the scent – feels quite intense and leans towards the masculine side, which I didn’t like. 🩷 My experience: After use, my hair didn’t feel as soft and moisturized as I had hoped. The scent was too strong for my taste, even though I appreciate that the conditioner is economical and I still have a lot left after four weeks of use. 🩷 Conclusion: Unfortunately, this conditioner did not meet my expectations, and it’s not something I would buy again or recommend. I had hoped for more care and a milder scent. #kerastase #lykotestpilot

      Hey Mathilda! 👋🏼 Thanks for your review, it's always interesting to hear about others' experiences 🩷 When I use this series, I usually use the mask as a conditioner every time - it feels a bit extra luxurious with all the care 😍 It's a shame that the scent didn't appeal to you, I would personally love to have it as a perfume 🙈 Take care 🌸

    Gives shine but not enough care

    I got to test this product as part of the Lyko Test Pilot program, in exchange for an honest review❤️ First impression: The packaging is nice and has a sleek design. The consistency is creamy and thick, which gives the impression of being caring. Experience: It spreads easily in the hair, and I like that it feels thick like a mask, but it goes quite a bit with each use. I leave it in for a few minutes before rinsing. My hair type: My hair is porous and dry. I wash my hair about once a week to avoid wear. Results: After use, the hair becomes shiny and soft while wet, but when it dries, it is still very porous. I haven't noticed any improvement in strength or reduced hair loss. Pros: • Nice packaging • Gives nice shine Cons: • Not economical – goes quite a bit • No noticeable difference in hair loss or hair strength #lykotestpilot #kerastase

    Good conditioner✨

    Kerastase conditioner Kerastase Genesis Fondant Renforcateur A conditioner for hair loss for weakened hair that tends to break. Kerastase Genesis Fondant Renforcateur strengthens the hair strand and increases the hair's natural resistance, which reduces the risk of hair loss. A combination of ginger root and natural cells from edelweiss, without weighing the hair down. I have tried this conditioner for 3-4 weeks and am very satisfied. The conditioner smells lovely and has a creamy consistency. After the first wash/use, I wasn't very positive. The hair didn't become silky soft and tangle-free. This improved after several washes with the shampoo. After 2 weeks of use, the hair became wonderfully soft and easy to comb. I have some curls in my hair, and the top layer of hair also curled nicely after using the conditioner. I look forward to using the conditioner through a full course of six to eight weeks to see full effect against hair loss and broken hair strands. #kerastase #lykotestpilot

    Sleek design with vibrant content!🌟

    I have had the honor of testing the conditioner in the #kerastase Genesis series as #lykotestpilot 🌸 The conditioner is the perfect companion to the shampoo and really contributes to enhancing the overall experience. The consistency is creamy and easy to apply evenly in the hair, and already during rinsing, the hair feels softer and more manageable. It detangles the hair effortlessly and gives a lovely shine that makes the hair look healthy and well-groomed. ✨ I find that the conditioner nourishes deeply and strengthens the hair over time, which makes it feel less brittle. Another great advantage is that the hair stays fresh longer, allowing me to wait a few days between washes without compromising the feeling of clean hair. 🌸 The scent is the same as in the rest of the series – elegant, a bit more masculine than traditional, and very salon-like. The sleek design of the bottle makes the product feel and look luxurious, and it’s such a detail that makes you want to leave it out on display. 💅 The only negative I have is that it requires a bit more product from the conditioner than I am used to in order to achieve the desired result, which is why I didn’t give it a full score 🫧 I really recommend this conditioner along with the shampoo in the same series 🌸

    Lovely balm with a wonderful scent 🌹

    I have been so lucky to be #lykotestpilot for #kerastase's genesis series, both shampoo, balm, and the serum. I love the shampoo and balm, they don't weigh down my Nordic fine hair and smell amazing. Really luxurious 🩷 I have only used them for a little over 2 weeks (received the products a bit late in relation to the review deadline), so I can't give a full assessment on whether they have helped with hair loss. But I can definitely say that I will buy the products again when I run out 🩷 The combination of the products feels really lovely, and I will definitely come with an updated review later 😍 I don't give the products full score on the star scale due to the price as they are quite pricey products and I still can't assess whether they are worth it in terms of purpose ☺️ #lykoreview

    Will definitely buy this again!

    I have long wanted to try products from #kerastase and was of course overjoyed when I got the chance to test this through #lykotestpilot. I think the product is economical, and you don’t need to use much! It makes the hair soft and smells very fresh. I feel that it reduces my frizz and makes my hair feel healthier and more moisturized! My hair is thin Scandinavian hair that is very dry and damaged! I’ve had a lot of frizz and missed shine! The shampoo and conditioner have worked wonders for my hair, it has become so soft and shiny in these 4 weeks without me using any other products. I will absolutely buy these again, my new favorites! 🤩

    Good with shine but maybe not as good moisture

    As #lykotestpilot I have had the opportunity to test this conditioner for a few weeks🚿 My hair type is: Straight, long, bleached/dyed hair with fine strands. Typically “Scandinavian”. I just had a baby, and with breastfeeding and all the other hormones swirling around in my body, my hair has taken a bit of a hit. This series feels extremely suitable for me and my hair. I have never had problems with hair loss or breakage before, but now it has unfortunately started to show a bit here and there. 💬 I must say that I am a bit torn when it comes to this conditioner. I think it feels okay but not so “wow”. It definitely gives good shine, which is a big plus, but I don’t feel that it moisturizes my hair at the level I am used to - and what my hair needs. Unfortunately, I also don’t find it to be that economical, but on the other hand, I have long hair, so of course it requires “more” product. I have a hard time expressing whether it strengthens the hair particularly much, but in combination with the rest of the series, it surely helps with that! The scent is luxurious and pleasant but quite strong. So if you are sensitive to scent and perfume, this is probably not for you. Anyway, a nice conditioner but maybe not the best on the market! #kerastase

    Good conditioner that gives shine and strength, but uncertain effect on hair loss

    #LYKOTESTPILOT #kerastase Thank you so much to Lyko for the opportunity to test this conditioner ❤️ I have been using it for about 3 weeks now, and I have a good impression so far. The bottle has a delicate light pink color with silver details that give an exclusive and elegant expression. The consistency is creamy, yet light, and I only use the conditioner on the lengths of freshly washed, towel-dried hair (as recommended), to avoid weighing the hair down at the roots. It distributes easily and makes the hair soft and shiny without weighing it down or making it greasy. I also notice that the hair is much easier to comb through, which is a big advantage! The scent is mild and fresh, and not too strong. I really like that, as I prefer products that don’t smell too strong in the hair, but still provide a clean and pleasant scent. When it comes to hair loss, it’s still too early to say whether the conditioner has an effect, but I notice that the hair in the lengths feels stronger and less brittle. This gives me hope that it can help prevent hair loss/breakage and make the hair more resilient over time. All in all, I find that Kérastase Genesis Fondant Renforcateur provides good care and nourishment to the hair without weighing it down, and it feels pleasant to use. I give it 4 stars because I would have liked to see a slightly faster effect on hair loss, but I am satisfied with how my hair feels and looks after use 🤩

    A good conditioner

    This conditioner was used in the same #LYKOTESTPILOT as the shampoo, and I must say it delivered consistently well throughout the entire period. I have thick, straight hair that easily gets tangled after washing, so I'm always a bit skeptical about whether conditioners really make hair easier to manage. This one did! The consistency is creamy and smooth, and it is very easy to distribute. I applied it from the middle of my hair down to the ends, and used the leftovers on my hands to comb through the top and scalp – a trick I got from my hairdresser to achieve an even distribution without over-saturating the roots. I let it sit for a few minutes before rinsing out, and my hair was soft and easy to comb through right away. The conditioner has a distinct and fresh scent that matches the shampoo – a bit strong perhaps for those sensitive to perfume, but I found it very pleasant. It also lingers in the hair after washing, which I personally like. When it comes to results over time, my hair felt both softer and stronger. I used a hairdryer and straightener occasionally, but always with heat protection. Still, my hair didn't become brittle or damaged at the ends, so I felt that the conditioner provided good protection and care. My scalp also didn't react negatively – no itching or dandruff. 💭 In summary: This is a good conditioner for you if you want shine, softness, and fewer tangles – without weighing down the hair. The price is a bit higher than affordable brands, but you get back for it in terms of quality and experience. I think especially you with normal to thick hair will appreciate this 💗🧖🏼‍♀️ #KERASTASE

    An average conditioner

    Unlike the other products in the Genesis line, I am not as impressed with the conditioner. To add, I have dry, blonde, and curly hair - which means I usually focus on moisturizing conditioners. I have felt that I have lost less hair than usual during these 4 weeks that I have used the line - yes, but in this case, the conditioner in the line would be the first product I would switch out for something more moisturizing instead. Unlike both the shampoo and serum, the conditioner comes in a completely ordinary tube. One thing that stood out to me about the shampoo was that the packaging was transparent, and it was easy to see how much product you were using. The conditioner’s packaging could be compared to any drugstore conditioner, just with an even more cumbersome screw cap. I will absolutely continue to use the product until it runs out, it’s not a bad conditioner, but for the price, you can definitely find something better. [hashtag] [hashtag]

    Excellent for thin/fine hair!

    I have now tested this product from #kerastase for 4 weeks and am at least very impressed. My hair type: 🫧 Thin/fine hair - also known as Scandinavian hair 🫧 Color-treated hair (Balayage) 🫧 Oily scalp 🫧 Issues with hair loss & broken hair strands I find it very difficult to find hair products for my hair type. Most of the time it ends up with my hair looking dirty, due to too much oil and heavy products or silicones. This conditioner and this series are without a doubt some of the best I have tested for my hair. I have previously used volumizing shampoo to make my hair look lively, but then had problems with dry hair. I then had a nourishing conditioner that led to my hair becoming stringy and looking unclean right after the shower. 🩷 This product makes the hair very clean and airy. The hair also feels very soft days after, which indicates a real impact on the hair strands and not just sits on the surface of the hair. 🩷 Something special that I have noticed when using this series is how easy the hair is to brush when it is wet (I am very careful with this and use a good brush that is meant for this). I find that the hair does not tangle and fall out, which is very rare for me. ✅ Economical formula ✅ Natural volume without compromising hair health ✅ Hair feels clean for a long time ✅ Soft for several days of use 🚫 Strong scent of rose, which I personally like. But it might be worth considering if you are sensitive to scents! #lykotestpilot
