Positive Hair Repair

K18 is the best hair repair product I have ever used. I have lightened hair on 50% of my head. The ends split very easily and quickly after trimming. K18 smoothed out the ends, softened the hair and made it feel like silk. No more split ends and dry hair. Best product ever.

Excellent product

I have medium length double processed hair that needed help from dryness. This has totally changed my hair. It is soft and easily manageable now. I only need one pump. I will reorder. Yes, it is worth the price in my opinion.

K18 does appear to improve the condition of color treated hair

I have only used K18 twice, but I do believe it has improved the texture of my hair. I highlight my hair and I’ve been looking for something to help battle frizz and breakage. Most products I’ve tried have left my hair feeling greasy and limp. K18 seems to be doing a decent job controlling the frizz without leaving it limp or greasy.

I have thick wavy hair. This product makes my hair feel healthy and silky, without the frizz!

Not Feeling the Love

I wish I could say I love the K18 Hair Mask but sadly it doesn’t work for my hair. I had expected great results using it on my very long dry natural curly hair but it did nothing but leave my hair stringy looking and without curl. I have tried using just one pump but that still leaves my hair without curl and just as dry as ever. I will continue to use one pump at least a couple of times a week and maybe it will eventually help. It may be a great product but just doesn’t work for me. I am very disappointed!!

K18

Loved K18! Made my hair feel great! My hair was in bad shape due to heat and frequent hair coloring. Also, I am 68 yrs old and have what I call “old lady hair.” In some areas like above my temples and the top of my head I have thinning and the hair it self is a different texture than my other hair. K18 makes it feel thicker and like healthier hair. Love K18! Bought 4 more bottles of it!

No Results

Sorry but this hair treatment did not make any difference on my hair. Actually you sent me another product as a sample and that worked perfect. So sorry did nothing.

BEST Bonder on the Market!

K18 biomimetic hair science leave in mask is the absolute BEST hair repair bonder on the market today! I have used everything, and I mean everything, from in salon services to product systems, serums, and treatments. I have platinum blonde hair and regularly double process color it at the salon. I have used this product twice and my hair is completely transformed. Before this, my hair was dry with broken ends. Now, it is smooth as glass yet, miraculously, it adds major volume, health, and vitality. There is nothing else like this out there. I am NOT a paid reviewer; I picked this up when it launched. I will always have K18 in my beauty bag. For those of you who highlight or bleach, this product is a MUST!

Very happy

I have very fine long hair with a lot of shorter hairs sticking out. After using K18 for 6 consecutive treatments, my hair is softer and much more manageable. It looks silky too.

K18

This is a revolutionary conditioner. I have highlighted hair that needs lots of help. K18 makes my hair look shiny and healthy immediately, and it leaves my hair very soft. I love this product.

Works ok

This repair hair mask works ok, but it left my fine hair too soft and limp. I used the minimal amount, but it was still to heavy for my hair.

K18 Leave in Hair Repair

I have used this product 5 times, consistently with no other conditioner, as recommended. My hair seems to be a little smoother, but since my hair is in such bad condition, it will probably take more than 5 times. I'm optimistic!

Nice treatment

I really like this treatment repair mask. You don’t need a lot but my hair feels nice, shiny and strong. My hair is highlighted and frizzy so this helps. It smells pleasant and is easy to use because you use it like a leave in and just comb it through. I would buy again.

Already see improvements

This product has definitely shown improvement in my chemically treated hair. It looks shiner and feels stronger. If you have fine hair like myself it does wait it down a bit. I only use one pump and that seems to get the job done!
