    Fantastic

    I had very dry and itchy scalp, as well as dry lengths before. I decided to try another hair care, of which this product is one of the new products in my hair routine (I also use Neccin No1 + No3, Sp Wella Luxeoil Keratin Restore Mask, Maria Åkerberg Scalp Treatment Mentha, Kérastase Genesis Thermique leave-in, Olaplex No 9 and Kérastase Elexir Ultimate L’Hulie Originale Hair Oil. Very different series and brands, that is). I use this after washing my hair, and it has really helped to fix my problems. Today my scalp is calm, and the lengths have a lot of moisture, the wear between salon visits is also less than it has been before, I lose less hair, my hair feels stronger, and it grows faster than before. I have nothing negative to say about this product. A super product! ⭐️ #lykosocial #lykoreview #kérastase #serum #lykoreviews

    question

    which of this and the genesis serum should I use? I have "vikar" which is a bit thin-haired, so I would like all hair that has been cut off due to extensions to grow out, and that the layered hair should grow and become as long as the rest of the hair, as well as stimulate hair growth in the rest of the hair🤔🩷 I have no other problems with hair loss from the scalp

    Unrealistic Use

    I only bought one bottle, so I can't judge if the hair growth got any better since the bottle ran out right away. It requires a lot of product to cover the entire scalp, and I still have thinner hair. It feels unrealistic to be able to do any long-term treatment with this product considering the price for the small bottle. If I were to recommend this to anyone, it would be for those with very thin and short hair, spot treatment for balding spots, or for the hairline.

      Hey Mariam 🤗 Fortunately, you don't need to use so much product when applying, this is how the product should be used 🙏👇 Apply a maximum of 3 pipettes of Sérum Extentioniste along the key scalp areas, one to two times a week. Use your fingertips to massage the serum into the scalp, in circular motions.

      Hi Beatrice 💗 This serum should be applied 1-2 times a week, max 3 pipettes along the most important scalp areas 😃 Use your fingertips to massage the serum into the scalp, to get it properly distributed. I hope this will suit you 🥰 Good luck!

    Kerastase serum

    Hey!! I have received both the Kerastase resistance serum and the Kerastase Genesis serum for the scalp, should I apply both every evening or use one of each every other day? What do you recommend?

      Hey Louise! How fun that you got these two serums I think you should start using the Genesis serum, once a day, in the morning or before you go to bed When the Genesis serum is finished, you can start using the Resistance serum, then you'll get the best effect and stronger hair follicles Have a nice afternoon

    Positively Surprised

    I bought this mostly to try it out and didn't have high expectations. After using it about 1-2 times a month for roughly 5 months, I am positively surprised, as the little hairs are finally starting to gain length. It takes its time, but I definitely see a difference. About my hair: I have bleached, brittle, and very dry hair that needs a little extra love. Since I bleach both at the salon and at home, sometimes the hair gets bleached out or 'worn out' from styling and everyday life. But after I started using this after about every 4-5 washes, the hair quality has improved (on the new growth, not so much on the lengths). I find it to be long-lasting and it holds up quite well. I will definitely buy it again as I am very curious about the results after longer use (with this, patience is key if you want to see results). #tävling #lykoreview

    Very good

    Haven't used it for so long, but it feels so good, my hair is already much shinier, a bit thicker. I've gotten a lot more baby hair.
