For a man, do not be bald or shave your head leaving little hair. To suit small eyes you should have an outrageous hairstyle that sprouts out like a mohawk or spikes. Your hair will look best straight and stiff, as opposed to women.
For a woman, you will look good if you have your hair "out" - this is hair not in any particular style - and a fringe makes it look slightly better. Wavy or curly hair seems to occupy your face more. After all, small eyes, big hair!
