Anywhere on the head where hair does not obstruct the piercing process, a piercing can be made. There are nine primary types of head and facial piercings. Most have sub-types that describe their appearance and position in greater detail.
The most common facial piercing types are ear, nose, lip and eyebrow piercings. In addition to those piercing types, there are anti-eyebrow piercings, cheek piercings, earl piercings, septum piercings and oral piercings. Earl and septum piercings are sometimes considered a more extreme subset of nose piercings, but the placement of earl and septum piercings are different enough to warrant their own categories.
Anti-eyebrow piercings are surface piercings placed in the upper cheek, beneath the eye. Cheek piercings are internal piercings usually placed where the skin dimples, though that can be changed due to the preference of the person receiving the piercing. Cheek piercings sometimes require minor surgery to remove. Earl piercings are horizontal piercings that pass through the bridge of the nose, usually between the eyes, where the most flesh can be found. Most people have enough flesh for this piercing, but some do not. Septum piercings are piercings done inside the nose, through the wall of flesh separating the nostrils from each other. Oral piercings are piercings inside the mouth, including tongue piercing, as well as piercing the gums between the lips and teeth or under the tongue.
