-Using a towel gently dry hair until damp.
-Begin with one mL/one dime-size amount of K18 Mask.

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.

INCREDIBLE

Probably the greatest hair product on the market. Instantly detangles and moisturizes. You can even feel how hydrated it is when washing your hair again. Now a must have in my routine. LOVE this brand.

Damaging

So, after hearing all the hype, I decided to give this a try on my fine, bleached (but somewhat healthy) long hair. I followed the instructions and was expecting positive results. Instead, this product completely damaged and changed the integrity of my hair. It was shocking, to say the least. My hair ended up frayed, frizzed, brittle and felt like straw. I could no longer even get a brush through my hair. I tried to reverse the damage by using deep treatments. But unfortunately nothing helped, and now 6 months later, my hair remains damaged by K18.

Best Bond Builder!

If you dye or heat style your hair, you need this product! It has done more than any other hair product to improve the health of my hair, and that is saying a lot because I am obsessed with trying new hair products! I received this from My Trendmood Box and was so excited to get another as I have been using it for a couple of years now and will not go without it!

Helps improve appearance of hair

The product helps with the appearance and management of my hair. My hair is super dry and damaged due to weird changes in texture and use of straightener everyday. I use as instructed, but on hair wash day my hair is back to its awful dry self! I don’t see any improvement in my hair without the product. After application, hair is once again more manageable. I pair this with the K18 molecular repair oil to further help the appearance of my hair after styling. I deducted one star because unfortunately it doesn’t seem to actually repair hair in the long run.
