How Can A Man Make His Hair Curly?

Use hair gels. If you want to use hair products to
get your hair curly, the best way to do it is with hair gel. Regardless
of how your hair is styled, using a pea-sized amount of gel and running
it through clean hair can help you curl it up however you want. Take the
time to make individual curls, or run your hands through it quickly for
a messy look.

• After rinsing your hair, squeeze a small amount of gel into your
  hands and run your fingers through your hair, from the forehead to the
  back. Let it start to set up for a minute, then take a pencil and wrap
  little curls of hair around the pencil. Count to 30. Keep working your
  hair into tiny curls until you like the look.
• If you have less time, try just running your hair through your hands
  quickly and getting your hair to stick in a lively, curly-looking
  position. If you don't like that crunchy hair gel style, try using a
  softening gel, which can help to keep your hair
  extremely soft, as well as train it into curls.
