Starting the bleaching process! You mix the powdered bleach with the developer, in a glass or plastic bowl. Mix with a brush, until completely creamy. Wear a shirt you won't mind getting stained, and open a window a bit, the bleach smells very chemically! Apply the bleach to the desired hair, I wanted an ombré, so I only applied to my jawline. The bleach covered hair was then wrapped with foil.
