Wait a minute. Do not purchase Clorox, and do not think about applying it to your body in any way.

The bleach you want comes from the beauty supply store. Ask for a 40 volume developer(peroxide bleach). Then find a dye that matches your hair. Ask what needs to be mixed with it.

I always have mine done by a pro, so follow the advice of the sales person.

While you are at the store, find a swimmers shampoo like Ion that has a high propylene glycol content. Wash out the bleach and the dye with it.

Use the same shampoo daily.

Cutting your hair to 1.25" would be a great idea.

I always recommend using Zydot the day of the test just to be sure...
