Leave-in Molecular Repair Hair Mask - Treatment for Damaged Hair

Love it but use properly

Used before & didn’t rate it but after using it properly the difference in my hair is amazing. Never thought I would get a brush through unconditioned hair but it does. Hair is transformed from dry & wiry to soft & shiny. Will continue to use once I have the initial 4-6 washes. Use it properly & wait for the results ✨

Transformed my damaged hair

K18 is a lifesaver for damaged hair! Super easy to use and totally worth the price.

I hate how much I like this product because it’s so expensive. Every time I use this, my hair looks so healthy and nice. It seems like my hair is 25% more “obedient” as styling it has gotten easier. RIP if you have long hair.

Hit or miss results, little product for full size

I have mixed feelings about this one. I am extremely disappointed by amount of product since I didn’t use it that much, I honestly have an issue with being consistent with beauty routine and it ran out so fast. The product itself is not bad but it gave me different result on few occasions and it’s frustrating. I have low porosity fine hair and it’s really easy to overpower it, so few time after using it my hair looked dirty. But other times it looked really good, like it made it look thicker and fuller. I hope I can find something better. I wouldn’t be super exited if I had to buy it again.

bleach blond hair best friend

I have highlights and my hair kept breaking, it has been a lot better since I started using K18

Did nothing to my hair, neither good nor bad. Just didn’t work. Would not recommend

Good repair treatment

Seems odd to not use conditioner beforehand but seems to be really working after two applications and hair is as soft as if conditioner had been used

Completely retexturises hair

Very expensive but you only need a little and its a must have for me now as it completely retexturises my hair and looks amazing .

Perfect

One of my essential products for heavily highlighted hair. Wouldn’t be without it

This product has helped restore my hair’s texture after getting blonde highlights. After using 3-4 times, my hair felt smoother and less coarse. The hair mask also works wonders on tangles.

OVERHYPED & UNDER DELIVERS

This leave-in mask does NOT work. It doesn’t do anything. I've used the product for over a month and have noticed no change in the health or texture of my hair. I wash my hair twice a week, and follow the instructions, and... nothing. It actually gives my hair the weight and texture of being dirty or having a lot of product in it. I chose it for ease of use vs. Olaplex, but I'll definitely buy Olaplex next time.

Great for fine, low-porosity hair!

Great option for people with fine or low porosity hair that can’t handle heavier bond or protein treatments. I use this 4 to 6 times after I get my hair colored. You do not need a ton of product. Make sure you use this before using a conditioner or leave detangler. And wait for four minutes before applying conditioner or detangler once out of the shower.
