I do think my hair felt smoother after use and I noticed less knots even after my hair had been in a bun all day. Decently easy to use. I like that it has a locking mechanism so I won't accidentally spray it when I drop it or something. What I don't like however is the scent, it has this fresh salon baby powder scent and it's much too strong for my liking. The scent does last for those who like it. I only used it once, no re-application, and the scent lasted for 4 days.

Edit: The scent isn't as strong when used on damp hair compared to on dry hair

Leave-in Collagen Serum Treatment

I first tried the Leave-in Collagen Serum Treatment in September, and I immediately noticed the difference in my hair. From the very first use, my hair felt softer, smoother, and much healthier. It wasn’t just a temporary change — over time, I could see that my hair looked shinier, more nourished, and less frizzy. The serum has a lightweight texture, so it doesn’t weigh hair down or leave it feeling sticky, which is perfect for daily use.
After seeing such great results, I loved it so much that I ended up buying two more bottles to make sure I always have it on hand. I really appreciate that a little goes a long way, so each bottle lasts for quite some time, making it a great investment for anyone looking to improve their hair’s overall health.

The scent is nice, and when I spray it at the end, it helps control frizz, making my hair look definitely better.

I struggled to find the lock mechanism. It's displayed too small and the instructions are weak. The reviews are good, so I'll give it a try anyway.

It's easy to apply, which I like. But the scent doesn't smell like apple at all. I was really surprised at first because it smelled like makgeolli, but fortunately, it changed to a soapy rose scent about 30 seconds after applying. It's interesting.

I could feel an improvement right after using it on my hair, which is great.

It quickly softens my hair without getting my hands dirty when I spray it. I use it every day during busy mornings.

The scent is really well done.. It's familiar but doesn't smell cheap, although it can be quite strong. Those sensitive to scents might not like it. I've been using the Moroccan Oil Shield Spray, and now that I've tried this product, the oil really helps control frizz and there's not much clumping.

I was worried about my hair being damaged from frequent blow-drying and dyeing, but I found this leave-in collagen serum treatment and have settled on it. The biggest advantage is that there's no need to rinse it out, which significantly reduces my busy morning routine. I just apply an appropriate amount to wet hair and let it dry, and I can feel the collagen ingredients being absorbed deep into the hair, making the previously frizzy ends noticeably firmer and giving it a bouncy elasticity. Since it's a serum formulation, it doesn't leave any stickiness on my hands and finishes off feeling fresh, and even after blow-drying, the subtle fragrance and shine last all day, which I'm really satisfied with. I highly recommend this item for those who want both convenience and nourishment!

It's a product that you can easily spray on, so I'm using it comfortably!! The scent isn't really my preference, but I like it because the effect is good!!

Since Kiu made it, I trusted it and bought it.

I usually don't bother with treatments, but this one is super easy because you just spray it on. You can use it on wet hair after washing or on dry hair, so you can enjoy smooth hair anytime. Highly recommended! 🫶🏻🫶🏻🤍

The scent is nice and it's easy to apply, so I like it. I bought it really cheaply with the Hemeco box.

It has the scent of fermented traditional liquor. It's not too oily or heavy.

This product can be used on both wet and dry hair without making it greasy, which I love. The scent is not strong and is subtle, which is nice. After washing my hair, I spray it 3-4 times on wet hair and comb through with my fingers, and even with long hair, it becomes incredibly smooth and well-organized. After drying, if I spray it once or twice on the ends of my hair, it prevents static.

I'm almost done with one bottle, and I liked it so much that I repurchased it. When I wash my hair, I bend over, and since I have long hair that reaches my waist, it often gets tangled after washing, which makes it hard to dry as it gets caught on my fingers and pulls or hurts. I can't apply oil near the scalp because it makes my hair greasy if I apply it too high. However, after buying this product, I towel-dry my hair and spray it from the ends to the middle a few times on wet hair. Then, I comb it with my fingers and gently tidy up to the scalp with what’s left on my hands, and my hair becomes soft, making it easy to dry immediately. When it's dry, I just spray a little more on the ends, and it eliminates static without any stickiness or greasiness.

I have long hair that comes down to my waist, so treatment is essential. After shampooing, I towel-dry my hair and spray this on, and it makes my hair soft. The scent isn't my favorite, but it's not overpowering. I've almost used up the whole bottle and will repurchase it~

It's comfortable to use and even with the oil mixed in, it doesn't feel greasy, which is great.

It works well when I apply it, and it makes blow-drying easier.

The scent is really nice and it tames frizz perfectly. It's just right for winter.
