Available in drugstores for $10-$13 this works just like ONO ColorFix & I've used it before to stip my hair of old haircolor pigment that had gotten muddy looking from repeated coloring with different brands & colors. It gently removed all the artificial pigment from my hair & left a fresh base to re-color without frying my hair. Much easier to use than ONO as this product is premeasured & the applicator bottle is provided (with ONO you do your own work & provide your own supplies, as needed). I've stopped all my crazy home haircoloring experiments for a while & have pretty much tossed my wallet to the hair salon for my haircoloring needs (for now). I need a little break from all the you-never-know-what-you're-going-to-get-with-this-new-box-color madness. Next time I mess up my hair color, I know I can depend on ONO to help me "delete" it (& then probably skip over to the hairdresser for a color correction & highlights...) lol.
