Review (5/5): Keeping Red Hair for Months! Even into the Pandemic
This was recommended to my wife to help her keep the red hair that she had professionally dyed. She's been using it for about 6 months and she has only needed to have a professional touchup once in that entire time. This stuff works!
I will say however that it does stain the shower or tub if it has grout. And the shade of red the this is (with it is in your hand) could be alarming! It does kind of look like blood. However, it does work well and if you stand the color and potential staining while using it, you will like this a lot!
