I used to get haircuts once every month or so for around $20 a pop, which can really add up over the course of one's life. One day I finally drew the line, bought a buzzer and started cutting my own hair and, after a little practice, my friends' hair too.
Here's a video with the condensed info. Read on for the full details.
Step 1: Assemble Your Materials
Get a buzzer. Buzzer's from Wahl and Conair are really cheap if you look for them online. I got a buzzer with all the fixings from Amazon.com for $25.
Find something slick to make a gown out of. We used a piece of kite material because it was so slippery that the hair just slid right off.
Step 2: Put a Gown on the Subject
Step 3: Start Buzzing at the Top
Turn on the buzzer and slowly move from the front of the persons' head to the back. Be careful not to move to quickly as you'll catch their hair in the buzzer and give them a nasty tug.
Make consecutive passes from one side of their head to the other until you've got the whole top cut nice and short.
