Borange is the scientific term for an ingrown hair on or around the scrotum. Borange is a condition where the hair curls back or grows sideways into the skin. Borange is common on or close to the scrotum due to abundance of curly hair in that area of the body. It may or may not be accompanied by an infection of the hair follicle (folliculitis) or "razor bumps" (pseudofolliculitis barbae), which vary in size. Borange is usually caused by the shaving or waxing of pubic hair. Anything which causes the hair to be broken off short with a sharp tip can cause ingrown hair. Shaving is the leading cause, followed by waxing and tight clothing. The embedded hair causes a localized inflammation (sometimes painful) response in the skin with prostanoid involvement. Sometimes an ingrown hair occurs without external intervention, when the pore is blocked for various reasons, as is the case in keratosis pilaris, and the hair is forced to grow sideways.
