Put a shower cap, aluminum foil, or clear/white plastic bag over your hair. Make sure it's not covering your face, but is over all of your hair. Then tie it at the nape of your neck, making sure all of your hair is tucked underneath the bag.  If you want a higher lift, use aluminum foil instead of a plastic bag. If you are using a grocery bag, make sure the side with printing on it is NOT against your head, or you will wind up with the color of the print processed into your hair a bit. Start timing from when you first started applying the bleach. Check your timer. If you leave it on for longer, it won't get any lighter, it will only damage your hair more.   Check the color all the time. Once at a pale yellow, you must wash off the bleach. Don't leave bleach on for over an hour. Don't bleach any more once at pale yellow or your hair will break. If you’ve gone as long as you safely can and your hair is still not pale yellow, then rinse it out, tone your hair, and wait a month to re-bleach your hair.    Wash out with a PH neutralizing shampoo. This will stop any further acidic or basic chemical reactions from occurring on your head. This will formally end the bleaching process.  You ‘’must’’ wash out the bleach mixture completely, or else you will damage your hair. After a while, the developer and powder stop reacting and your hair won't bleach any more, only become more damaged. If you over-bleach, your hair might end up feeling a little bit straw-like and brittle. If you're in doubt, rinse it out. Make sure to use a shampoo and conditioner designed for bleached blonde hair to eliminate any yellow and make your hair bright platinum and white. Any purple shampoo is fine. Remember purple counteracts yellow, makes it white, and eliminates brassiness.
