    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

    Usage

    Hi, How often should you use this? I have tried it 2 times, the first time on wet hair after the shower and on dry hair before I was going to bed. Felt incredible both times BUT how often should I use this? Is it every night or after every shower?

      Hello Sara 🤠 How fun that you like this, it’s so lovely! 🥰 You can use it every evening on dry or towel-dried hair. If you want, you can also apply a little after showering on damp hair for extra nourishment and shine ✨ Have a nice day 🌸

    Kerastase overnight serum

    Should this be applied to the hair every night or just occasionally?

      I believe this product works best on wet hair if you want the product to penetrate the hair strands. When the hair is wet, it is most fragile and absorbs the product best. And I would recommend letting your hair dry completely before going to bed. I would let the product sit in the hair for about 5-10 minutes, apply hair oil, and heat protection. Then I would blow-dry the hair dry, using cold air afterwards, so that the hair's "pores" close in the product. I would sleep with my hair in a loose braid or a loose hairstyle, or use a pillowcase/hair bonnet made of fabric that creates minimal friction. If there is a lot of frizz when you wake up, you can probably use this product or hair oil in a small amount on the lengths/tips of your hair!

    Strange smell

    Good consistency, doesn't stick to hair. Hair feels soft in the mornings. Next, I will try the protein-free version, it will surely work even better on highlighted hair. [hashtag]

    Not the best product

    After all the good reviews, I thought I would try this on my hair. It dried quite quickly into the hair and didn't feel greasy the next day, but it didn't give more than that, the hair didn't become any less dry than before, so I won't be buying a new one either, it wasn't worth the price. No product beats Olaplex No. 3, it works wonders for the hair.
