    Game changer

    Saved my hair. I don't think people realize you have to use this for weeks before it really helps. I have bleached hair and this brought me back from years of damage. Put a tiny bit in hands, rub hands together to form white paste and put into hair. Don't rinse. Let sit for 5 mins before styling. Game changer. Hooked for life. I have hair past middle of my back and this container lasts me over a month

    Does nothing

    I purchased this hair mask as it was recommended by a dermatologist. I used this hair mask exactly as directed on the bottle. It did absolutely NOTHING for my hair. Plus it is so pricey: for a little bottle of 0.5ml to pay $18 is ludicrous...especially because it does not deliver on its promise. Do not waste your $$ on this product. I have used other hair masks that I purchased from Target that were very good.

    Noticeable results after one use

    I could see the results after a single use. I have virgin hair that I don't heat style, but it is very fine, brittle, and highly prone to mechanical damage. After one use my hair was noticeably smoother, shinier and better behaved. The only drawback is the price.

    Helped give my blonde/dyed a boost!

    Loved that this repaired my hair without being super heavy! It is quite pricey IMO for such a small amount but would def buy again anyway

    Did absolutely nothing - waste of money

    Wanted to try this since it was so highly recomended and I have a bit of damage from lightening, but I wanted to make sure it was really worth the price before committing to the larger size, so I only used it on one side of my head in order to really see the difference. Followed the directions exactly and finished the whole bottle... with literally no change. Even asked my hair stylist if she could see any difference at all and she couldn't (she also said I should have seen some change by now). So ended up being a total waste of money.

    target K18might be a fake

    If you want k18 you need to purchase k18 from Sephora, I had a k18 bottle from Sephora and it made my hair look and feel shiny healthy alive but this k18 from target didn’t do anything it only detangled it

    Hype not worth it

    It’s really expensive for no reason. I don’t really see a difference in my hair from using a more affordable hair masks that’s under $25 compared to k18 which is half the size of any other hair masks bottle. I have long hair down to my butt this will literally only last two weeks my hair is still frizzy. Don’t recommend waste of money. 5/10

    Really upsetting product

    I was so excited to try this. My hair is in good shape but what’s a little extra help when you have dyed hair right? Maybe get some extra shine and even better shape?! I regret even knowing about this product. I used as directed and it made my hair dry frizzy and EVERY SINGLE one of my hairs has a split end! I had just had a trim and no split ends! My hair keeps tangling and feels oddly thinner than before I used it! It also left a weird tiny bald spot which is very upsetting. I know not all products work for everyone but this was a horrible experience. I would not recommend this product.

    Blondies need this

    If you bleach your hair, you need this. I have been bleaching my hair for 15 years and this has repaired my hair more than oloplex or any of the other products I have tried. I use it once a week as a conditioner in my hair.

    Wow

    This stuff is expensive, but I cut off all my hair to start over from damage I did from dieing and then one use. I noticed the significant difference in my hair me and my 14-year-old daughter love this stuff too bad it’s so expensive and you definitely don’t need your conditioner when you use it just the shampoo dry your hair and put it in, amazing my hair felt amazing
