DIAMOND
Diamond face shapes are not so common. They are characterized by a narrow forehead and jawline, with the cheekbones being the widest point of the face. The cheekbones are often high and defined on this face shape.
With diamond faces, the goal is to add fullness or texture at the forehead and jawline, and to avoid fullness only at the cheekbone area. Short styles can work well on this face, but they should be shorter than ear-length and should include some sort of bangs. Center parts also tend to create an unbalanced look on this face. Along with short styles, chin-length and shoulder-length styles are also great choices. You may use a flat iron to make the ends kick out or look choppy. Blunt cut, straight bangs highlight this face's beautiful cheekbones, as do side parts. Even tucking hair behind the ears shows off the gorgeous cheekbone features this face shape has.

The bottom line when it comes to face shapes is that each has positive attributes that can be accentuated with the appropriate hair cut, style and texture. There is no 'perfect' face shape, so work with what you've got, get recommendations from your stylist, and become the most 'perfect' you you can be.
