I figured the impossible out for keeping red hair for months w/o fading/causing a headache! Step 1: mix manic panic red w/ Ulta red shampoo as seen above into a bowl (About 2-4 dime size drops/about 4-5 tablespoons of shampoo) wash whole head then rinse. Step 2: Cover head w/Ulta red glaze let sit for 3-5 mins then rinse. Step 3: Lather ulta conditioner into the bottom half of hair (avoid roots) then rinse Wash hair every 2-4 days using dry shampoo in between washes! --Need to tryyy!
