When you want to lighten your hair color but you don't want to shell out the high cost for a salon dye job, home bleaching using ammonia and peroxide will get the job done. These common household products are the perfect fix for any budget-conscious fashionista who wants to shake things up. In an afternoon, you can go from blah to beautiful. Just be sure to touch up your roots every four to six weeks.


Divide your hair into four sections with two in the front and two in the back. Clip each portion up. You'll be working your way from section to section.


Toss a towel over your shoulders and pull on the plastic gloves. You're working with some serious chemicals so protect your skin and clothes.


Mix the ammonia and peroxide together in the bowl. Use the tint brush to mix it up thoroughly so that you have a paste the consistency of smooth guacamole. Yum.


Take a 1-inch piece of hair from the back of your head and brush it with bleach paste. Leave about 1/2 inch of hair near the root since the heat from your scalp speeds up the lightening process. You'll go back to the roots later.


Paint on the paste, one section at a time. Work fast because bleach starts working the moment it touches your hair.


Brush bleach onto your roots then work that paste into your hair using your fingertips.


Wrap your head in plastic wrap to keep the heat and moisture in.


Watch the clock and watch your hair. The bleaching time will vary depending on the color and texture of your hair. It could be as quick as 10 minutes or as long as an hour. As it lightens, it will turn a rainbow of scary colors like copper, orange and yellow before hitting blond. Peek in your hair every 10 minutes to track its progress.


Remove the plastic wrap once your hair has lightened. Run to the shower and immediately rinse out the bleach.


Smooth conditioner onto your hair, then leave on for five minutes before rinsing.
