Must have
I really didn’t want this to work because how expensive it is…. But wow it works insanely good. I have naturally curly hair but have dyed my hair a few times, and just after 6x washes my curls are finally back it’s actually insane how well this works

Hair fell out
I’m not sure what happened with this product, I have been on a healthy hair journey and growing out my blonde so I decided to try this product to use in place of conditioner(like it says) and within two uses I experienced huge hair loss and and reeling about what this product did to my hair. It felt incredibly dry and frizzy and will never use a product from this line ever again, left me in tears!

Tiny but mighty!
There aren’t many items I consider “holy grail” level, but this is definitely one. There seems to be no damage too destructive for this mask to repair—I’ve had my hair dyed, permed, and bleached and after I was done with this mini bottle my hair was back to its normal, silky texture! If you’ve been on the fence about this, run immediately to pick it up!

Notice a difference
One bottle lasts me 2 months, it’s a game changer for my hair helping it not to break and I don’t use it with any other k18 products. I noticed immediate results which is why I’m not that upset about the price, at least it works!

So dry
So I have fine hair and maybe it’s not meant for fine hair but it always leaves my hair like straw after and it’s extremely hard to saturate throughout your hair since you can’t use conditioner before. It took about an hour to get the product through my entire hair I don’t think it makes any difference besides that either

BEST HAIR MASK ON THE MARKET
This product has changed my life. From broken split ends to healthy long hair in just 6 months. You see results as early as just a few weeks. Love love love it. 10/10 recommend

Nope
Absolutely not. I’ve tried it multiple times. My hair always feels dry and frizzy after.

Worth it! Make sure you are using it right though!
Yes it’s expensive but it works! I have long blonde bleached hair and I’ve noticed a difference in 2 uses! I’ve purchased this in the past and noticed no difference and hair was super hard to brush since I wasn’t conditioning as per the instructions.. HOWEVER, I started, clarifying shampoo, then normal shampoo, towel dry hair with microfibre towel, apply this product in sections to your hair. Then I put it in a claw clip for 4 mins then comb it through my hair. Lastly I put conditioner in my hair then rinse! Game changer!

Love it
You only need 1-3 pumps (depending on hair amount) because emulsifies when you rub it between your palms. Separate your hair into sections and 1 pump per section. Recommesections.

Leave-In Molecular Repair Hair Mask
Must have for healthy hair
100000/10 MY HOLY GRAIL if I could recommend a product for your hair it’s this K18 leave in mask. My hair was pretty managed from being Platinum blonde - Brunette . I wanted my hair to feel ALIVE again!! And K18 did the trick! I was a bit hesitant not to put any product after shampooing my hair.. but I’ve followed the instruction and after leaving the mask on for 4 min and blow drying it - it was magical ! My hair felt super soft, healthy, shiny and the ends felt rejuvenated as well. Highly highly recommend
