Consider your face shape and any specific challenges you may have while selecting the haircut or hairstyle that best suits your face shape and personal style. Oblong (long), diamond, inverted triangle, heart, oval, round, and square are the six basic facial forms. In some cases, the words "rectangular" and "pear-shaped" are also used. Even though it's simple to get confused, the most important measures to take are figuring out whether your face is on the wider or narrower side and what your strongest facial feature is.
