What are Pilar Cysts?

Pilar cysts are small, chicken skin-like structures that form on the scalp. Pilar cysts on the scalp are common and harmless. They are not a sign of any serious health problem. They’re sometimes called trichilemmal cysts or wens. 

A pilar cyst is also called an epidermoid cyst and it can occur when a hair follicle gets clogged. Pilar cysts can develop anywhere on the body but they are most common on the scalp.

Pilar cysts begin when the outer layer of the skin sheds old skin cells. Sometimes, cells can shift under the surface of the skin instead of falling off. Due to this, the shedding cells start to grow by multiplying themselves and instead of moving up to the surface, they get trapped under the skin and begin to build up.
