I have dark brown hair at shoulder length and I really want to go Shakira blonde. How can I go Shakira blonde without having my hair to fall off?

Go to a professional stylist. They'll know exactly what to do in one session, rather than doing it yourself at home and bleaching and dying and dying and bleaching until you get the right shade. A good, top-shelf salon conditioner will also help prevent your hair from falling out or breaking.
