Update to this post about cutting my own hair. →[More:]
I got thinning shears and a razor comb and hair scissors from Amazon. No pics, too lazy.
It really worked. I washed my hair and combed it all forward, and cut it straight across. Then I used the razor comb to comb through the last two inches or so. When I flipped my hair back, it was layered and tapered. It's magic, I tells ya. Magic!
