Saw it with my own eyes

I purchased the mini starter kit. My Hairstylist used the mask and oil on my hair during a previous appointment. I completed the wash and had my hair wrapped up in a white drying towel made from bamboo fibers. I was shocked to see pink / red on the towel ! I wish I had taken a photo! It was literally the hard water deposits that so many of us don’t realize are coming from our shower! Also, for reference, I have long hair that is bleached blonde. My hair color was not affected other than it looked more healthy and shiny. I followed the instructions and applied the repair mask once mostly towel dry. Waited 4 minutes, gently went over my hair with a detangling comb and styled using very little product. I did apply some K18 oil after styling. Had one of my best hair days this year. On a Tuesday no less. 😂
