For the genuine do-it-yourselfer: How To Cut Your Own Hair

4. Simple styles are best for home hair cuts. The easiest cut will be one length everywhere. Decide on an overall length (it’s a good idea to measure your hair when you have a cut that you find especially flattering) and then grab your ruler. Working in small sections, comb your hair straight out from your scalp and hold a section smoothly between your index and middle fingers. Measure to the desired length and carefully snip off the excess. Continue in this manner until you have cut all of your hair. This method works equally well for both men and women. The length of the chosen cut can vary from quite short to shoulder length and beyond.
