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

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.

Super satisfied
The hair becomes silky soft the next day. It takes very little product for a very good result. I use it about every other night or every third and am super satisfied with the purchase. Will buy again
