I waited a few days to write this review so that I could use this product and give a well-rounded review. My first impression is that this product made my hair extremely soft. I have fine, long hair, and sometimes struggle with breakage due to being a natural blonde, but I also bleach my hair. It made my hair feel healthier in just one use! After multiple uses every night, my hair feels much more moisturized. I’ve noticed less frizz when I wake up, and overall softer hair. I bought a mini version of this product, which is still a decent size for how little product you need to use, but I already have the full size in my cart! The product smells great and has great slip (meaning it spreads evenly throughout hair easily). I will definitely continue using this product. My one complaint is not about the product itself but of the care taken whilst it was shipped; it was put in a bubble envelope rather than a box, so the product box came damaged. The product itself was undamaged, but if you wanted to give this as a gift I’d be hesitant if the box was as damaged as mine. Read more

Amazing product and works better than expected. Smells good too. Was worried cause it's pricey but well worth it. Really help my dry hair. Read more

I absolutely love this stuff. It’s definitely on the pricey side, but the results are wild. I wake up with my hair feeling incredibly soft, smooth, and hydrated without feeling heavy or greasy 🌙✨ A little goes a long way, and it absorbs really nicely overnight. My hair looks healthier and more manageable in the morning, especially on dry ends. Small downside: The price hurts a bit, but the performance backs it up. Overall, this is one of those products that actually does what it promises, and I keep repurchasing because it works so well 💛 Read more

This product is like magic! Makes my hair feel smooth and shiny the next morning. Worth the price. My hair did not look this heatlhy Read more

This product seems to work nicely on my scalp but I think it smells awful. It’s almost like a sulphur smell I often smell when walking into hair salons. A lot of reviews say it smells great but I think I’m going to have to put another product on after this to drown the smell of this. Read more

I’ve been using this serum overnight and my hair feels so soft, smooth, and nourished every morning. It smells amazing and doesn’t feel greasy at all. My hair looks healthier and shinier—definitely a staple in my routine now! Read more

I started experiencing severe hair loss 5 years ago due to surgeries from health issues plus PCOS and Endo. Oiling wasn’t working, I never put heat on my hair and it was so horrible balding and thinning when I used to have long thick hair, in July i chopped my hair short to start over and I bought this combined with nutfraol, and the other keratase serum. I used nutfraol in 2024 but it still didn’t help with thinning and breakage until I combined it with the other two keratase products. Only 5 months later and my hair is growing so fast and most importantly healthy. This product kept my hair moisturized and helped so much. My hair stopped breaking and is so easy to manage with this product. Losing hair is really hard but I’m so thankful I found something that helped. First picture is from July 3rd, 2025 and second and third picture is from December 3,2025. Very happy with the results. Read more
