Barbers are trained to cut and style hair using a variety of equipment that includes scissors, razors and most importantly, clippers. One of the most important aspects of hair cutting and styling is perfecting the shape up, which sets the edges and hairline of an individual. Doing your own shape up can be a way to save a few dollars; however, if you want it to look as good as a barber's work, there a few considerations.
Consult with a barber about the best type of T-shaped clippers to purchase. Purchase the clippers at a barber supply store or from a barber if they have a new pair available and are willing to sell.
Watch barbers perform shape up, perhaps during a visit to a barbershop to get your own hair cut. Pay particular attention to how shape ups look, including your own, considering that this will serve as your guide going forth.
In front of a mirror, press the edge of the clippers or razor against the tip of your front hairline and reestablish the hairline by slowly trimming across it. Hold a handheld mirror slightly to either side of your face in front of your larger mirror so that you can see the back of your head. Slowly trim across your back hairline with the clippers or razor.
Press down one ear and trim your hairline from the side. Clip extra hair that sticks out from your hairline by gently stroking your clippers or razor away from your hairline. Press down the other ear and trim your hairline from the side.
Pour a small amount of rubbing alcohol on a paper towel and rub it along your hairline. Use both mirrors to look at your hairline from all sides.
