Reddit mentions of Ion Color Brilliance Hair Lightener Powder Tub, 16oz

I tout Ion Lightener Powder like I'm in a commercial. It smells good, it's better for your hair than other bleaches, and it doesn't hurt your scalp. (don't forget developer!) 30-40 is recommended for dark hair, so I'd say 30 to be safe, since you already bleached it. You can also buy those at Sally's Beauty, if you have one near you. Since it's near your face, you can use foil to separate out your bangs from the rest of your hair and keep them off your skin while they're "cookin".
