At first it feels weird not to condition your hair after you wash it, but this stuff works! So amazing. My only con is it’s so expensive.

Stringy damaged hair
I've used this product twice and it made my hair so stringy and the slightest pull on my hair and I had chunks ripping out from how damaged my hair felt after using this product. For how much it cost it should be fool proof to use. I have tried adding conditioner after applying, and I have tried it without conditioner and still stringy. I only apply 0.5-1 pumps to my thin medium length hair, but my hair felt more damaged than it has ever been with bleaching. I'm not impressed at all with the price and knowing I'm not the only one who has been having hair snapping.

The best hair product I ever tried
This is by far the best hair product I've ever used. I am usually very skeptical to leave-in products, as they all leave residue. But not this one. My hair is very long and pretty damaged from all the dying, pool and sun exposure. It's very hard to get it untangled even after a hair mask and a conditioner. With this mask, my hair is so shiny and soft, I couldn't believe my eyes. I made a mistake and used too much of the product for the first time, but still my hair had no residue, it just felt heavy. The best part is that I don't need to use a mask and a conditioner, just shampoo and then this leave-in mask, so my hair washing routine became so much shorter (I usually have to apply some other products after all washing routine anyway to style it). I am reordering in a big size, and will continue using as this is a life-saver for my hair.

Heat Damaged Box Dyed Hair Holy Grail
I'm usually skeptical when it comes to hair masks bc I rarely find any that actually do anything but this product has become a holy grail that I will continue using. I have naturally curly hair with grays coming in so I heat style it every day and use black box dye on a monthly basis and I have noticed such a difference with just two uses so far. It has made the ends of my hair more manageable and less dry and overall improved the softness of my hair. I also bought the mini bottle to test it out in case it didn't end up working for me but I will get the bigger size once I run out. Instructions also mention to not use conditioner but I have curly hair so I didn't want to sacrifice that step of my hair care routine so I wash with shampoo then towel dry my hair and use the k18 mask for 4 minutes and then I go in with conditioner. I also saw a tiktok of someone who had emailed K18 and they said it is ok to go in with conditioner after the four minutes have passed because that is the amount of time the product needs to actually work so after that you can use conditioner if needed.

Best hair repair ever!
I have been bleaching my hair for years. Since covid I switched to doing it myself. Overlapping with different colors and taking out pigments I have stripped my hair to being brittle and brushing my hair it was just breaking off. Before cutting off all of the dead hair that was crispy and crunchy I picked up K18 based on reviews. This stuff works right away. It puts moisture back into your hair and makes it feel more healthy. You're able to brush your hair.

Post swimming routine
My toddlers are in mommy and me swim lessons each week. After each lesson, I use the peptide prep shampoo in the shower and the mask afterwards. Makes such a difference with all the chlorine exposure. Dropped one star because it does feel a bit heavy afterwards, and more difficult to style.

must get!!
This hair mask is so good!! My hair is super fried because I bleached it 3 times over the summer and I haven't found anything that gets rid of the frizz and moisturizes it, but this mask does exactly that. It's also super easy to apply.

Not for curly hair
If you have curly hair, don’t waste your money. Considering the high price, the results are disappointing. There are much better options on the market that work more effectively for curly hair.
