So good I don’t want to tell anyone

I ordered two more bottles as backs rock before I wrote this review, because I have a feeling this will be sold out frequently in the future. IT IS INCREDIBLE. I have long, blonde (colored), coarse, thick, wavy, dry, brittle hair. I’ve used another systems multipart “numbered” treatment for years and it did help some with the health of my hair. BUT K18?! A COMPLETELY DIFFERENT LEVEL. I’ve used it 4 times (I only wash my hair every 7-10 days) in the last month and everyone keeps telling me how long and healthy my hair looks. It is slowly repairing my hair, and I will never be without this again. I’m going to use it one more time, and then will start alternating every other week between this and the other hair system. This is expensive, but it works. It’s the shiniest, healthiest and prettiest my hair has been in 20 years (when I started coloring my hair). This is truly a phenomenal product.

Actually delivers results

After much research and reading other people’s results I finally took the plunge. I have long, naturally curly, medium-thick hair that is compromised from hard water and use of color/highlights. I don’t wash my hair daily (hair stylist’s advice) so I wasn’t sure how long it would take to see/feel results. I have applied this 4 times now and have some observations. The mind-blowing part is this product is applied to shampooed/towel dried hair. You are NOT supposed to condition so the K18 can directly affect the hair shafts. Trust the process, it works. Even though my hair is extremely tangled without conditioner, it is easily detangled with a dollop of this product. I use a pump on each section, finger raking and then brush through at the very end. (The first application I used too much, 1.5 pumps/section. You will need less if your hair is shorter or not as compromised.) Let it sit for 4min then continue on with styling. My hair remains softer longer and still holds a curl! I even like the curl pattern without my usual styling products! I will definitely repurchase. Side note: b/c this makes the hair smoother, my roots are very flat. I definitely have to root clip while drying. Also, others have reported there are 51 pumps of product.

Holy Grail Product!!

Finally, a product that worked in my coarse, curly, thick, color-treated hair! I would give K18 10 stars! It is very expensive, but you won’t be sorry. Make sure you follow the application instructions carefully, you don’t want to waste a drop (use a clarifying shampoo before first application and do not use conditioner prior to applying K18).

Don't hesitate...heal your hair--for less.

I was so afraid this would be a knock off. K18 lets me--a biracial woman with uber curly (3C/4A) hair --go BLONDE, with no hair loss whatsoever. Kept my length, and my hair is soft and shiny. Buy this. Now.

Makes my hair shiny and silky and brings out natural waves

I wasn't sure if this would help my hair too much because my hair isn't terribly damaged. I have some grown out highlights and breakage but I don't color treat my hair regularly. I used this on half of my head for 4 washes to see if it would show a noticeable differences, and especially on the 4th use I was blown away. My hair was shiny, and some natural waves that I have were much more defined (this was an unexpected surprise) and it tamed down the breakage and made my hair look and feel smoother. I am officially in love. I really like how easy this is to use and that you simply skip a conditioner and apply this as a leave-in treatment. Super convenient which means it is something that I won't mind using.

Excellent

This truly works! I had some damage due to some at home shampoo in hair color that I bought online….should not have used it after the first wash. It really thinned out my hair strands and made them brassy. It’s growing out now but I didn’t want to chop all my hair off. After a couple uses of k18 I could really tell a difference! The cuticle seemed to fuse together and be much smoother! I’ve only had to do minimal trims now! I have fine straight hair. It does take a bit to figure out how much to use. Less is more. I think you have to have truly chemically or heat damaged hair to see the results. It’s pricy. But it will last me a long time! After the first 6 times, I just use it in between as needed.

First time buyer

My daughter recommended this to me so I wanted to try bc I have been using olaplex. I do think this helps more than olaplex but I’ve only used a few times because I don’t wash my hair but 2 times a week.

Wow! Finally soft and shiny hair

I have thick, somewhat coarse and rather dull hair. K18 mad a dramatic difference in the softness, manageability and shine of my hair. It's so good that even my hands look better after using this. This should definitely be used on damp hair, not dry. I'm so happy that I haven't seen little white flakes after it dries. It does not weigh my hair down and in fact it makes my hair perky and much easier (and fun) to style. I love that this is not just a styling product, but that it actually makes the condition of your hair healthier. Beauty arises out of health. I definitely recommend this.

Must buy

I am so impressed with this leave-in mask. I have followed the directions and used the product after shampooing for about 4 times and my hair looks and feels so much healthier. Definitely notice less damage and split ends. This is well worth the price. I have shoulder length hair and only need one pump.

It works

I have color treated fine hair. Breakage is constant. This product makes my hair look better and feel better. I have only been using for a month so far so good.

Brings Hair Back!

I have used the K18 three times. The first time, there was a difference in the moisture level and sty lability. After three uses my color treated hair is soft, manageable and shiny. They recommend 6 uses. I love the results and I am only halfway!

Amazing!

This product has done wonders for my hair. I have tried endless products in an effort to calm and repair my hair and this is the first product that has truly made a difference. I have coarse wavy hair which needs both blow drying and a straightener to calm it down. This product leaves my hair soft and manageable even after just using my hair drier on partially air-dried hair. I originally purchased it to repair my hair breakage, so I'm hoping that will continue to improve as well, but it is worth it for the manageability alone. It is pricey, but this is the first time I've ever actually seen results.

Love it

I love this treatment for repairing my hair. The first time I used it I used way too much and my hair felt dirty and greasy, but the next time I used much less and my hair felt amazing. I have damaged hair from bleaching and this makes it feel healthy again. I am on my 3rd bottle and will continue to purchase. I have thick long hair and found that 3 pumps is good for me.
