Good Work
I used this product once a week for a detox from product buildup. It effectively cleans my hair without feeling like it’s being stripped. The colour caught me off guard and I’m not the biggest fan of the scent but it’s effective

Scalp irritation and itchiness
I only used this product once for wash day. I washed 2x and then followed up with my own deep conditioner. I noticed scalp irritation on the second wash and didnt really think anything of it. After rinsing out the deep conditioner and styling, the irritation continued and my scalp became VERY itchy. This is my first K18 product and now, I'm hesitant to try the rest of the line. Very dissapponted.
