The actual cause of the pilonidal cyst condition is still unclear. But most pilonidal cysts seem to occur by friction and pressure created from the constant rubbing of skin, tight clothes, longer periods of sitting, bicycling or due to similar factors. This pressure forces the hair to grow downwards beneath the skin in that area. The body takes these hairs as abnormal and begins an immune response against it and that immune response forms the cyst.

In rare cases, the above explanation applies to other parts of the body as well, other than the tailbone region. For example, people in certain professions may have pilonidal cysts formed in the skin between fingers.
