Thank you so much for that information. Must have been the henna treatment I tried weeks back. Overall, I was very pleased with the coloring and will continue to purchase EcoColors Haircolor. Just curious, so every time my hair salon colored my hair (semi-permanent color) and I lost my hair line each time (just dissolved), was that because their peroxide must have contained a bleaching agent as you mentioned? Thank again for the reply. I appreciate it.
