I decided it was time to cover my grays during the pandemic. My hair is naturally a light ash brown, so of course that's the hair color dye I chose. OMGoodness, it turned my hair a reddish brown, which doesn't look good next to my skin tone. I've tried several purple shampoos to tone down the red. Then I read about IGK's Mixed Feelings. I mixed 10 drops into my shampoo in the palm of my hand, shampooed it in, and let it set on my hair for one hour. After rinsing it out and blow drying my hair, the red is much less noticeable or vibrant. I'm going to continue with the one hour treatments for awhile and see how much more I can tone down the red. The little button on the bottom of the bottle is sooooo easy to use for dropping the correct amount into your shampoo or conditioner that's in the palm of your hand. My hair looks exceptionally shiny. I love the scent, too.
