If you have Salleys hair care store around you look and see if they have DARK ROAN RED you use it just like any other hair dye make sure you get the liquid not the paste.. Mix it with hot water or Kleen sheen or show sheen stir it real good and apply... Hope this helps we gotta red steer this year and thats what we used it made him a nice red color.. we use it on our shorthorns as well in the summer time to help freshin up the roan necked ones THATS JUST MY 2 CENTS hope this helps ya good luck WSC
