I'll show you my method for cutting my own hair using scissors and some clippers for detail work. Save money and time!
Step 1: You will need...
a good pair of ambidextrous scissors (that can be used in either hand),
a small mirror,
an electric clipper,
one or two plastic garbage bags to catch the messy hair clippings, one for the counter, and one for the floor.
These should all cost you less than $30 U.S. ($10 Canadien), but these will pay for themselves after one or two haircuts, so go ahead and get a very good pair of barber's scissors.
Step 2: Wash your hair, then cut the hair in front
Wash your hair and towel it dry.
Then, comb your hair, and get the part in exactly the place that you want it.
Next, comb your hair so that it's hanging down over your forehead and eyes.
Finally, cut the hair over your forhead so that it's just above your eyebrows. If you cut the hair much shorter than this, it will stick up and be unmanageable when it gets dry.
