I had a friend shave my head for me last time it got too long, but I believe in self reliance and I decided that if I couldn't maintain it myself then I didn't deserve this awesome haircut. Also, that friend is in Canada and I'm in California, so I was on my own as far as hair cutting was concerned.
Step 1: Materials
-big garbage bag (to wear as a smock)
-clippers (I ended up using two different models, but more on that later.)
-scissors (to cut arm and neck holes in the garbage bag)
Last time I got my hair cut I wore an old t-shirt that I didn't care about, figuring I could wash it afterwards. It got so many little hairs stuck in the fabric and no amount of washing would get them out. This time, I found a box of huge garbage bags in my garage so I decided to just wear one of those to protect my clothes and minimize clean up. It worked great and I would highly recommend it to everyone.
I didn't have any clippers so I bought these on Amazon and I think they were less than $30. I don't know much about clippers but Wahl is a reputable brand and the clippers that I have for my horse are that brand, so I figured they were good enough for me.
Step 2: Make your garbage bag into a smock
Step 3: Prepare your hair and workspace
If you are not intending to shave your whole head you should do something to keep the rest of your hair out of the way. I have long hair so I pulled it into a messy bun and also put a little gel on it too keep the fly aways at bay. If you have shorter hair, you might have to use hair pins or clips or even just gel to keep the rest of your hair organized. Just don't put gel on the hair you want to shave! Keep that hair clean!
The hair that I wanted to shave off was long enough that it was going in all different directions so I ran a comb through it to get it all facing in the same direction and make the part clearer.
For working space, if you have one of those mirrors that opens on the sides and lets you see all sides of your head, that's perfect. I don't have that, so I used the mirror above my sink and a full length mirror that's also in my bathroom. I'm sure you can figure out a set up that works for you using mirrors you already have!
This is also a good time to get familiar with your clippers. Make sure you know which clipper guard you want to use since that will determine the final length of your hair. Be sure that the clipper guard is securely attached to the clippers before you start. Start with one a bit longer than you think you might want. You can always cut more hair off! Turn them on and off a couple times to get used to how they feel, how loud they are and how heavy they are, etc. I held mine against my head while they were on (without cutting anything) to see how much they would vibrate and get used to the feeling before I actually started cutting any hair, since that's what I do with my horse, too.
