if you want a precise curls

use hot rollers. After applying the hot rollers to your entire head and allowing them to set, lightly brush the resulting curls and spray with hair spray to hold. You can also use standard hair rollers on damp hairor fashion your hair into pin curls using bobby pins and sit under a hair dryer until the hair is dry. Use hair spray to hold your new curls.



and if you want a loose waves :

try this quick and easy technique you can use to get a mass of curls.. Shampoo and condition your hair normally. Towel dry. Create a bun at the nape of your neck by twisting your hair as you shape it into the bun.

then apply hair spray called Shockwaves Curl Energy Spray from wella

Pin your newly formed bun into place.

Allow your hair to air dry naturally. When hair is dry, take the pins out of your hair and should have long, loose, sexy waves.
