Put on an old shirt you won't mind staining, then cover your shoulders with an old towel. Lay down some newspaper across your counter. If you want to, you can pull on a pair of plastic dyeing gloves as well. The bleach will be coming into contact with your scalp anyway, so the gloves are not absolutely necessary. Get a packet of hair bleach and 20 volume developer. Measure out 1 part bleach and 2 parts 20 volume developer. Mix the two together in a non-metal bowl with a non-metal spoon.  Prepare enough bleach to saturate your hair. Some bleach kits come with a little scoop. Use that to measure the bleach and developer. If you're wearing gloves, you can apply the bleach with your hands. Alternatively, use a tinting brush. Don't worry about being too meticulous here. Simply apply a light, even coat of bleach, then wait 15 minutes. The goal is to cover as much of your hair as quickly as possible.  This initial coat of bleach will ensure that your hair lightens evenly. Cover your hair with a plastic shower cap to protect your surroundings. If you have very light hair, you may only need to wait 5 to 10 minutes. Once you notice your hair starting to lighten, you're ready for the second coat of bleach. Do not rinse the bleach out. Simply take the shower cap off (if you put it on earlier), and apply a thick, generous coat of bleach. Use enough so that you can't see a single strand of hair sticking out of the bleach. Once you have it in, wait up to 30 minutes for the bleach to process.  Again, cover your hair with a plastic shower cap while the bleach processes. If you have light-colored hair to begin with, you may not need to wait the full 30 minutes. If you like the level of lightness your hair reaches, you are done! Rinse the bleach out with cool water first, then use some shampoo. You haven't dyed your hair yet, so you can use any type of shampoo you want. A mild, moisturizing shampoo would be the best, however, because it will make your hair feel nice and soft. It's a good idea to use a purple or blue shampoo after you bleach your hair. This will help tone down any brassy, yellow, or orange tints that remain in your hair.
