K18 is amazing

The k18 leave in mask works! I immediately loved what it did for my hair (Caucasian, curly, fine). Not only does my hair look & feel healthier, the mask some how managed to give my hair body - as in fullness -which I thought was never possible?! I was skeptical to buy because of the price but so glad I caved, I hope it never goes away. I highly recommend it, even if just a trial size, you might be thrilled with the results!

Treats Frizzy Hair

This product has improved my frizzy hair a lot. After about 4months of use my hair looks healthier and less frizzy. I cannot say my hair is fizz-less, but definitely way less frizzy than before. While some reviews mentioned it makes their hair oily, I have never noticed that. After applying it on my hair, it just get absorbed (I guess) and you cannot see/feel anything.

Amazing product line

Will be repurchasing. I was using it wrong the first time I bought it. Use this product as directed and it works. I use Olaplex 3 once a month.

Best out there!

This is a game changer for your hair! It makes it soft and hydrated. And beautiful after a blow out. If you’re not using this product it’s a must.

Magic

I waited until this was on sale to try, after reading rave reviews. First was didn’t notice much difference but after 3rd my hair is so much softer and shinier, which I didn’t expect with no conditioner. Definitely a need product now, I justify the cost because I don’t need a conditioner.

The Only Hair Product I'll Splurge on

My hairstylist used this on my hair after a bleaching and coloring session, I've been hooked ever since! Yes, this is expensive, but also yes, this is the ONLY hair repair product to dramatically improve the texture of my hair after I put it through bleaching and coloring. This is hair science at its finest!

Easier commitment than other options

As a woman in my 50’s, staying on top of healthy hair treatments is becoming more of a priority. My hair is colored and shoulder length, looking better with K18 and less frizzy than it has in years. What I do know is this process is so easy, I can do it consistently. I am using a bit more than a dime size amount after shampooing, and repurchased two more bottles. LovelySkin’s sale price encouraged me to give it a whirl and I’m pleased with the results.

K18 Leave-In Mask

I’ve used K18 leave in mask after shampooing 5 times so far. I only use 1 pump on my long hair. The trick (saw this on Tik-Toc) is to use sparingly by pumping (one time ) a dollop on my hands and rub my hands together until the gel turns white on my hands, then apply to my semi dry hair . Leaving on my hair for 4 minutes, then blow dry as usual. I’m noticing my hair feels silky, soft and healthy . I’m happy with my purchase, will probably buy again. It definitely has made a difference in my hair texture compared to the other conditioners I have previously used.

Great mask

I use it every other day after shampoo and my hair is shinier and softer! Expensive but maybe worth it for some of us with dry hair.

Great leave-in

I have tried many types of hair repair systems and masques…and always use a heat protectant for my color-treated hair. This K-18 Leave-in is now one of my favorites. It really works!

Blows other bonding products out of the water!

Very impressed by this product, although I wish it was gluten free.

This is my third bottle

My hair is constantly breaking and splitting where I get my highlights and this product has made that better. It conditions your hair without weighing it down. I will continue to buy it. I have thin bleached hair, so I need it.

As good as everyone says!

Every influencer and TikTok user under the sun has recommended this product. I’m always skeptical of hair repair products, because there are so many on the market that don’t deliver. This is amazing! However, it is spendy, so it’s definitely not going to be for everyone.

New must have

Recommended by my hairdresser for post color treatments and now as a weekly addition to my dry winter hair. Helps moisturize and detangle with ease.

Better than Olaplex!

Yes, this stuff is expensive. But it works on my fine, highlighted fragile hair and it works better than Olaplex, in my opinion. Definitely worth trying!

Love this stuff.

I like this even better than olaplaex for me. I get tangled really bad and the K18 solves it completely. I think the leave in rather than rinse out is good. I will repurchase when getting low.

Impressed

I’m really liking this hair treatment. It makes my hair feel soft, smooth and healthy. It also styles well after I use it and my hair lasts another day or two before I need to shampoo.
