    • Best for Dry/Damaged Hair
Size: 1.8 Fl Oz (Pack of 1)
I have been using this product for my very dry hair for the last week or so. The price is great for what you get! When I wake up in the morning my hair is so soft and I can feel the overall difference of the health of my hair.

    • Not sure it’s worth the hype?
Size: 8.5 Ounce (Pack of 1)
I guess? Nice shampoo but wasn’t life changing. It washed my hair and had a nice scent— not too perfumed. I don’t want to knock it but I think it’s just fine. Hair is soft and moisturized.

    • Game-Changer for Damaged Hair!
Size: 8.5 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

    • K18 Shampoo and K18 Conditioner are fantastic products
Size: 8.5 Ounce (Pack of 1)
K18 smells Yummy. Do not use too much as you will be surprised at all the lather it produces and although the product is more expensive than some, it doesn't take much K18 to have squeaky clean hair. It is a high-quality product. I love it!

    • Great for healing bleach damaged hair
Size: 8.5 Ounce (Pack of 1)
Bought for my daughter who is trying to repair her bleach damaged hair. She has thick, curly hair that gets dried out easily. The bleach caused a lot of breakage and this product has helped strengthen her hair a lot. It’s also made her hair softer and shinier. She swears by this brand and uses several of their products together. ... show more
