Tried and true - it actually does repair serious damage

Everyone's said it already but I can't rave about this enough. Recently I got a strand of hair (front piece/bangs) so severely damaged from bleach, sun and water exposure that it almost completely changed texture - my entire hair is straight/lightly wavy, and that particular strand got rough, dry, curly and frizzy and not even a blowout would make it smooth. I started the recommended treatment cycle with K18 and, after a few weeks now, my hair is almost completely back to normal. I'm still quite shocked with the results - I've never seen a product perform at this high level and would NEVER expect that level of damage to be reversed. Yes this is expensive but if you need serious damage repair, this will actually deliver.

Amazing, even for virgin hair

I have wavy, thin, virgin hair, almost never use hot tools, never had my hair dyed and still, my hair looks brittle and frizzy all the time. My curly products fade away after a few hours, and I can't use the stronger ones because they make my hair look greasy and weighted down. This product is amazing. My hair has a more defined shape, and helps my curly products work better. Never looked so good and repaired. You can have virgin hair and still be damaged, this product can help you in this case too. It's very pricey, but it's worth it.

MUST PURCHASE

Wow. Wow. Wow. Never have I ever had more shine and healthier hair. After months of using this product I can say with guarantee if you’re on the fence, pull the trigger!  Some helpful tips: Before using activate the product by rubbing btw your hands so that the color of the product is white.  Apply all over your hair and let sit for 4 minutes. DO NOT USE CONDITIONER AFTER SHAMPOOING

Nothing special

This mask made my hair feel a bit heavy/sticky after blowdrying. I’ve only used it a few times now so will see what the results are in the upcoming weeks. However, there are much better masks out there for a cheaper price.

Good but expensive

Good results with minimal effort (I get the same results from Olaplex nr 3 but have to leave that one in quite a bit longer). However price is pretty steep. For the people who say it doesn’t do enough for them; try emulsifying the product in your hands first before applying. I’ve been told you sort of need to activate it before putting it in your hair.
