K18 Detox Shampoo

I was a bit leery if the detox shampoo was necessary for my colored and toned hair. However, I noticed a nice change after one use. My hair seemed to hold a style better and feel healthier. I'm looking forward to continue using it.

Game Changer Stuff!

I live overseas and haven’t found a stylist I LOVE yet, so I have had to be extra mindful with my at home care, especially since I regularly color my hair. The Brazil sun and chemicals totally dry my hair out and when I use the detox shampoo (and leave in mask) my hair is totally transformed. I went home last month and my stylist said she could feel the difference in my hair. Yes this product line is pricey but I do believe it’s worth it and it cuts my wash day routine in half. My hair feels so clean and healthy after using this shampoo and ready to be styled with no issues. Before & after pictures of dryness then shine.
