To lighten your hair with hydrogen peroxide, spray it on your hair until you achieve your goal shade. Each treatment takes just seconds to apply, and successive applications intensify the lightening effect. The supplies you need for this procedure are hydrogen peroxide, an opaque plastic spray bottle, liquid hand soap, a mirror and a hairbrush.
