All drabbers work with permanent color, so if you are trying to use this on NATURAL hair -forget it.

 Now if your natural hair has just turned reddish do to being in the sun, then you can buy a product that is a Blue conditioner or a blue shampoo, which will drab your natural color down and take out the red tone, but you'll need to keep using it.

 If you want to try color you can move to a demi permanent - NOT permanent, DEMI PERMANENT which will NOT lift your natural color it just deposits the tone yopu want, use a color level that is lighter then your level, because all demi deposit darker, so if you are a medium blonde level 7 then use a level 8.

I would recommend is Clairol's Complements DEMI permanent in level 8A ash tone and you need to buy the Color Prompter, which is the peroxide that mixes with the color in equal parts. The color comes in a tube that you open by using the end of the cap to puncture the end of the tube and then mix one tone of color to 2oz. of Color Prompter, mix and apply to all the hair for 15 minutes and rinse & shampoo & condition.
