The 5.5 centimetre rule

Before you make your decision, you should follow this simple rule. Simply measure the distance from your earlobe to your chin. To do this, hold a pencil horizontally under your chin and place a ruler vertically under your ear. If the point where they intersect is less than 5.5 centimetres, go ahead, you passed the test and you can cut your hair as short as you like. If the measurement is greater than 5.5 centimetres, it is advisable to cut your hair not so short.
