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.

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!
