Can't beat this deal

I highly recommend getting the jumbo bottle of K18. You will love the mask and it's a great steal. I recommend this product to anyone who colors their hair regularly. Your hair will always feel soft and freshly done.

This worked wonders on my 4B super coily, dense hair. Follow the instructions, you really only need 2-3 pumps, no extra conditioner needed.

My hair has been so much softer since I started using K18. It’s been around 6 weeks now, and I’m so glad I discovered this product!

It really strengthens my hair, and my haircuts last longer.

I think K18 is perfect for new clients who are hesitant to invest in a product they haven't tried yet. It makes their hair instantly soft and healthy looking in just 4 minutes.

I shampoo, apply one pump before blow drying, and I don't need any additional products. My hair comes out so smooth. I love it!

After years of dyeing my hair, I finally grew it to hip length, but the ends were dry and damaged. After trimming about an inch to remove split ends, I used K18 (6 washes in a row, then once a week) and now I feel confident that my hair will stay soft and healthy without needing to cut more. This is one product I’ve repurchased multiple times because it truly works, especially as I continue to dye my hair.

I wanted beautiful, highlighted hair for my wedding, and using this for about a year beforehand helped me achieve that goal.
