  • Excellent Conditioner
Size: 8.50 Ounce (Pack of 1)
This stuff is great! It really moisturizes my hair and leaves it soft and easy to comb. Smells nice, too. Highly recommend for dry, color-treated hair. It's a little pricey, but worth every penny.

  • Game-Changer for Damaged Hair!
Size: 8.50 Ounce (Pack of 1)
I’ve tried so many products for my dry, color-treated hair, and K18 is one of the few that actually delivers noticeable results. After just a few uses, my hair felt softer, smoother, and much stronger. The shampoo cleanses without stripping, and the conditioner leaves my hair feeling hydrated but not weighed down. My hair also has more shine and less breakage, which is a huge win. Definitely pricey, but a little goes a long way — and the results make it worth every penny. Highly recommend for anyone dealing with damage or just wanting healthier hair! ... show more

  • $3000 spent on hair products & this is my fav go to
Size: 8.50 Ounce (Pack of 1)
The media could not be loaded. Hello, so I really do like this one allot. I have spent about $3000 on higher quality hair products over the last cpl months bincluding this line but out of ALL the leave in conditioners I've bought I like this one the best. The bottle is a great size at 8.5 oz, is very creamy & lasts a long time. What's also a plus to me is it still works great on top/over every other product I've put in my hair. In my video you'll see it is a thicker consistency compared to most (& all of what I've bought) & this works out best for my hair which is colored, damaged, dry & frizzy. Also what I love is that I can always use it on top of everything else I have in my hair even if I'm on the road & have not washed my hair for a few days but keep using product I can still wet my hair with my fingers/hands & reapply this & it is like new! I'm not sure if it helps with shine but it does make my hair softer & most of all helps with the dryness & with taming most of my frizz. This one can also be used on wet or dry hair. If your hair sounds like mine definitely give this one a try. ... show more
