Works better than competing products that I have used
I am not ready to go completely gray yet, so it sounds weird, but I will color my hair about once a month.  It's usually too dark and I don't want to be obvious, so after I wash out the color, I will wait 5 minutes or so, then shampoo with this and let it sit for a few minutes, then rinse.  It's just the right combination.  Also, if you get a little too crazy with the color and it's too dark, use this with each shower for a few days afterwards and it gradually blends in with the gray.
