A very short pixie cut with bangs brings out the cheekbones on diamond features. Diamond face shapes tend to lose width below and above the cheeks, thus short haircuts with bangs suit them nicely. Longer bangs highlight the lovely cheekbones and widen the temples.
For women with platinum short thin hair, an undercut pixie with a fringe is a great option. Pixie cuts with an undercut will make your hair appear thicker and also promote better hair development.
