    If I could give more stars, I would!!

    A product I will NEVER stop buying after this. As a Lyko influencer tester, I get the chance to try products and then give you, as usual, an honest review. So much fun! And extra fun when it becomes a product that has been missing in my hair routine. This has honestly given my hair a new life. Giving my hair a serum filled with moisture means I wake up every morning with vibrant hair. I honestly don't think I'll ever stop using this serum? It's so good that I find it hard to see how I could live without it. If you need moisture and are only going to buy 1 product, buy this!! If I could give more than 5 stars, I would ⭐️⭐️⭐️⭐️⭐️ 🍀 Perfect to put in the lengths before going to bed as it works for 8 hours 🍀 I wake up with softer hair 🍀 You don't need much product 🍀 Filled a gap that wasn't in my hair care routine haha 🍀 Good pump and large bottle 🍀 Doesn't weigh the hair down Just hair products are the absolute most fun to test, I think, especially when they hit SO WELL!! 🙌🏼 #LYKOINFLUTESTER #KERASTASE

    Strong perfume and makes hair greasy

    I really wanted to like this and join in on others' praise for this product… but unfortunately, I don't like it at all. 1. The scent is too strong, intense, and lasts until the next day and beyond if you don't wash your hair. OK, I thought, I'll survive it if it's otherwise a good product. 2. The hair became shiny right away. Looked promising! I felt like it quickly absorbed into the hair. 3. The morning after, the freshly washed hair from the night before feels greasy and oily as if I had spray and other products in my hair (a feeling I don't like). 4. The hair became rough and tangled more easily. Tried again with less product but the same story. 🤷‍♀️ For reference, I have long, uncolored hair with natural waves that is quite dry. #lykoreview

    🤎LOVE🤎

    So WOW for this product! I have gone through two bottles (this one is almost empty) and have just accepted that I will have to keep buying! It has become one of the absolutely most important steps in my hair routine🤎 🔗 Does not weigh hair down or make it greasy 🔗 FEEDS with moisture 🔗 Use it both at night so it can work overnight but also right after showering! 🔗 Makes hair soft, easy to brush, and shiny! 🔗 Nice packaging, economical and lasts a long time! Some think it smells too strong, I think it smells MAGICAL GOOD!🤎 Highly recommend and if you haven't tried it, do it!! #lykomission #lykocreator #keraste #hår

    Kérastase Nutritive 8H Overnight Serum 30 ml

    I have used this product before and have been very satisfied with it. I think it moisturizes my hair and makes it less tangled overnight and easier to brush. I also think it smells really good and the scent is not overwhelming. All in all, I have been very happy with this product for a long time now and give it 5 stars.

    Kerastase 8H Overnight Serum

    A nice serum. I use it before going to bed. Every time after using it my hair feels silky and moisturized. For me the scent is not as divine as people have been saying but it’s pretty nice. I have really dry hair because of the summer sun so I hoped this would help me with it, for now there hasn’t been that big of a change, but I keep on using it ✨

    Best hair product ever

    So satisfied

    Love this! Have repurchased it many times and it makes my hair so nice every morning! Reduces frizz but doesn’t weigh it down at all.

    Difference from regular leave-in?

    Hi! What exactly is the difference between this and a regular leave-in? Do you need both or is this one enough?

      Hi! 😊 Kérastase Nutritive 8H Overnight Serum is an overnight treatment applied to lengths and ends before bedtime and works for up to 8 hours while you sleep. It is primarily designed to nourish and combat dryness. A regular leave-in is usually used after washing to make hair easier to detangle, provide care, and sometimes protect the lengths during the day. So you don’t need both. Choose the 8H serum if you mainly want an overnight treatment for dry hair, or add it when you want to give your hair extra overnight care ✨

    Magic for the hair🧙‍♀️

    Love this product!! ✅Wake up with smooth hair! ✅One of the few products my thin, frizzy, and curly hair has appreciated ❌There’s probably only one negative thing to say, the price. But if you want to invest in a good product, this is definitely it!!

    Good for thin and frizzy hair

    Recommend it to my (peri)menopausal ladies who over the years have gotten thinner hair with a frizzy quality. (Grrrr). Got the tip about this serum from a friend in a similar situation as me who I thought had gotten such beautiful hair. You wake up and the hair may not look like before, but it is definitely shinier and healthier. Started noticing effects after a couple of uses. Am now on my second bottle and will not stop using this serum. It is expensive but you have to take the chance when it’s at a good price and order.
