Having naturally black hair is impossible. 2 Virgin hair is generally level 2/3 at its darkest. 3 For natural dark hair, use Brilliant Blonde with 30 Vol developer on lengths. 4, Use 20 vol for a second application if the hair has not lifted sufficiently. 5 Lighten by following steps 1-4 until you find a color that's right for you. 6 If you want to go further, repeat step 5 with new colors until you find one that's perfect. 7 Once you've chosen the final color, lock it in with strong conditioning treatments for several months so your hair will stay bright blond. 8 To make your hair even brighter, add a few drops of Redken Colorlift Liquid Gold to each application of brilliant blonde. 9 The gold ingredient also helps prevent hair from going back to its normal color. 10 To create a more colorful effect, mix equal amounts of brilliant blonde and redken color lift liquid gold. Apply as usual then follow up with a rinse out after three or four days. 11 To keep your hair bright blond forever, use regular trims to remove any colored hairs before they turn brown again. This will help your hair remain healthy and shiny. 12 Avoid using heat appliances like irons or curling rods on blond hair. The heat can cause damage that will only be apparent later when you try to grow out your hair.
