Sometimes we need some courage to get our hair cut. If you are wondering if your hair suits your face shape, you can do this application. This amazing method is created by the famous British stylist and hair care professional John Frieda. Its name is Rule 2.25 (inch). According to Frieda, you only need to read a ruler, a pencil and the following items to see if short hair suits your face shape. Place your pen horizontally under your chin. Hold the ruler vertically towards your face. Measure the distance to your chin, starting with your earlobe. If the distance is shorter than 5.70, short hair will suit your face.
