Luxury feel and lovely scent🤍✨
I was excited to test this serum, as it promises care and strength for the hair ✨ The first impression was very good – the bottle feels luxurious, and the product immediately gives a “salon feel” 🤍💆♀️ I have used the serum regularly during the testing period, and although I haven't noticed any big or obvious difference in my hair, it still feels very nice to use 🫶🏼 The consistency is light, it absorbs quickly, and it doesn't make the hair greasy or heavy 🙌✨ I have normal hair and am used to using caring products, and maybe that's why I didn't notice any major results this time 🤍 But the hair feels softer after application, and the scent is absolutely lovely 😍🌸 Very fresh, clean, and luxurious – typical Kérastase. In terms of results, I would say that this serum provides a nice finish, softness, and care, but for me, there wasn't any wow effect over time ✨ It probably suits you best if you want a luxurious serum that gives a good feeling, shine, and light care, rather than visible, drastic changes!❤️ #lykotestpilot #kerastase 🤍✨189 views - Most helpful negativeThe post was made 2 monthsRating: 2 out of 5
Had expected more.
I got the chance to test Kérastase Première Sérum Filler Fondamental, and unfortunately, this product did not live up to my expectations. I have tested it for a couple of weeks, both on dry hair and after I have washed it. It is economical, you don’t need much product at a time, and the consistency is good, easy to work with and disappears nicely into the hair. The smell reminds me of a hospital, very sterile scent. So based on my hair type, which is dry, thin, and frizzy hair, this was not a product for me. But considering the price, I had higher expectations. I am participating in a test panel and received a free test product.234 views - The post was made 1 weekRating: 3 out of 5
Light serum that gives a softer feel
I had the opportunity to test this product as a test pilot and have used it for about 4 weeks on both towel-dried and completely dry hair. My hair is colored, has finer Scandinavian quality, and easily becomes frizzy/dry in the lengths. I wash my hair 1-2 times a week. The serum has a light and smooth consistency that is easy to distribute and does not feel heavy or sticky. On towel-dried hair, it gives a softer feel and makes the lengths more manageable and easier to detangle. Reduces frizz and makes hair shinier. On my hair, the product works best right after washing and for about a day before it becomes drier/tangled again. In dry ends, it works well for a little extra softness and shine for the moment. I need to complement it with my regular hair oil for a longer moisturizing effect. I rarely style my hair but find that heat tools give a better and more lasting result. The packaging feels exclusive and the scent is pleasant without becoming strong after application. The formula is economical, and the hair does not feel greasy or weighed down. Considering the price, I expected a bit more effect (softness/shininess), but I will continue to use the serum in combination with another hair oil. #lykotestpilot #kerastase137 views - The post was made 2 weeksRating: 5 out of 5
Gives softer, stronger, and healthier lengths
Première Sérum Filler Fondamental is a hair serum that quickly became a favorite in my hair care routine. My hair is treated and can sometimes feel dry and brittle in the lengths, especially after coloring and heat styling, so I’m always looking for products that both care for and strengthen without weighing the hair down. The serum has a silky and light consistency that distributes easily in the hair and immediately gives a soft and supple feel. The hair doesn’t feel greasy or heavy after application, but instead gets a natural shine and a healthier impression. I appreciate that it works just as well in towel-dried hair as in dry hair for extra care and finish. After using the serum for a while, I notice a clear difference in the quality of my hair. The lengths feel stronger, less dry, and look significantly healthier. The hair is easier to manage and feels more resilient against wear. A very good serum that provides both immediate effects and long-term caring results. #lykotestpilot #kerastase183 views - The post was made 2 weeksRating: 4 out of 5
New favorite in the cabinet!
I had the pleasure of testing this serum from Kerastase, and here’s what I think: 🩷I naturally have a bit of frizzy hair that quickly becomes frizzy, especially after blow-drying. 🧴 I use this serum on towel-dried hair after washing, only on the lengths before I blow-dry. 💧 The consistency is light and serum-like, and I was initially a bit worried that it would feel heavy, but it absorbs quickly and doesn’t weigh the hair down at all. 🌬️ The result after blow-drying is fantastic! The hair becomes incredibly soft, smooth, and easier to work with, and it has significantly less frizz. ✨ The hair looks healthier, feels well-groomed, and stays nice throughout the day. 💖 This has become a staple in my hair routine, and I can really recommend it to anyone looking for softer hair and better control over frizz. 🫣The only negative I have to say is that the product is a bit pricey.. ⭐️⭐️⭐️⭐️105 views - The user's roll: Lyko Creator.

Beautiful and shiny hair with Kerastas
I had the chance to try the Sérum Filler Fondamental Hair Serum and Sérum Cellulaire Nuit Anti-pellicilaire Intensif from Kérastase. I love the consistency of both, they feel super luxurious and smell amazing. Both products feel very moisturizing, and the Sérum Filler Fondamental Hair Serum (which was my favorite) gives a fantastic shine while the hair feels “calm” and restored. I tend to have frizzy hair, and the strands lay nicely even when styling with curls and a flat iron.102 views - The user's roll: Lyko Creator. The post was made 2 weeksRating: 5 out of 5
Stronger Hair🥰
An HONOR I have had the honor of testing two products from Kérastase as a Lyko Influtester – and I am honestly blown away 😍✨ One of them was the Kérastase Nutritive 8H Overnight Serum 🌙✨ This is a product I will never stop buying. The serum has given my hair incredibly much moisture and life, and I wake up every morning with soft, manageable, and vibrant hair 🤍💧 Perfect to apply to the lengths before bedtime as it works for up to 8 hours 🌙🙌 The product has a light consistency, is economical, doesn’t weigh the hair down, and has a really good pump 🧴✨ If you need moisture and are only going to buy one product – I have truly seen positive results! I am so grateful to have tested this product and to have gotten stronger hair🤗 #lyko #test #snyggarehår113 views - The post was made 2 weeksRating: 5 out of 5
Kerastase Filler leave in serum
Kerastase filler has become my new favorite hair product. I was so lucky to get to test the product from you. It has a lovely clean scent. Gives smoother hair and anti-static (frizz). Before, I used hair oil for my tangles, but now I can skip that. Now I use this on towel-dried hair. My hair feels fresher, smoother, and smells lovely. I feel it gives some moisture to the hair as well. It has a stylish silver bottle. This is my favorite product from Kerastase, highly recommended. The product is expensive, but it really has quality. Also a plus that it has heat protection in it. #lykotestpilot #kerastase #lykoreview157 views - The post was made 2 weeksRating: 5 out of 5
Kerastase Premiere Serum Filler Fondamental Heir serum
I had the opportunity to test the Kerastase Premiere serum for four weeks. The serum is applied to towel-dried hair, let it sit before blow-drying the hair. My first impression of the serum was that it smelled good, the bottle feels luxurious, creamy consistency. The serum gives a nice shine, the hair feels softer, smoother, and frizz-free for several days after washing. Recommended for anyone struggling with dry, frizzy, and damaged hair. #lykotestpilot #kerastase146 views - The user's roll: Lyko Creator. The post was made 3 weeksRating: 5 out of 5
Positively Surprised!
I have been so lucky to test Kérastase Première, and this product really impressed me 🤍 I love the packaging, both the design and how easy it is to apply. The bottle feels exclusive and practical ✨ The product is also very economical in use, so you only need a small amount per application. Personally, I was most curious if it could calm down frizzy hair, and here I was positively surprised! 💫 I have used it about 2–3 times a week on dry hair, and it really helps against frizz. The hair feels smoother, more well-groomed, and has a lovely scent🌸✨ That the product is also heat-protective is a big plus 🔥🙌 I would absolutely recommend this product to anyone who wants shiny, soft, and frizz-free hair 💕🎀 #lykotestpilot #kerastese188 views - The post was made 3 weeksRating: 5 out of 5verified customer
Kérastase Premiére Sérum Filler Fondamental Hair Serum 90 ml
I feel like my first year as a mom has really shown on my hair, I have always had thick hair, but if there’s one thing I’ve gotten this year, it’s frizzy hair, and my hair has simply taken a toll. My first thought when I held the bottle for the first time was, LUXURY! The product comes in a glass bottle, and I think you get a reasonable amount of product with just one pump, and not only that, it smells incredible. I have mainly applied the product as described, on towel-dried hair. But I have also tried applying the product to my hair when I’ve felt it was frizzy, like after I’ve had my hair up in a bun. My hair has felt tired and frizzy, and I feel like the product does its job. It reduces frizz, and I think it makes the hair smooth, it doesn’t weigh the hair down. I’ve also curled my hair once when I used the product, and I don’t know if I just had a good hair day or if the curls held longer with the serum in?! Either way, I was satisfied with the result, and the product does its🥰 The only downside I have for the product is that it’s a bit too expensive, but I would absolutely treat myself to the product if I felt like I wanted a refill.✨ #lykotestpilot #kerastase174 views- The user's roll: Lyko Creator. The comment was made 3 weeksYes, pregnancy and "mom hormones" are not particularly nice to the hair, unfortunately. Fun that this product works well. 🙂 Kérastase is really quality, even if a bit pricey sometimes... you have to watch out when there's a sale.

Soft and smooth hair.
I have been so lucky to test out Kérastase Première Sérum Filler Fondamental Hair Serum for 4 weeks. I just have to start by saying that I love Kérastase products 🤩 Since I don't have damaged or frizzy hair, I couldn't see the effect the product was supposed to have. My hair became silky soft after the first application 🤗 But considering that I have completely natural hair, this product was too heavy for my hair. But if I had dry/frizzy and/or treated hair, this product would have been spot on 👌 In terms of scent, it smells a bit intense at first, but that fades quickly. The price is high, but the product is economical to use. #lykotestpilot #Kèrastase154 views
