Ingrown hair lump (cyst) Causes

Hair follicles (the root of the hair) grow underneath the skin while hair strands grow outside. 

When someone shaves, they only remove the strands of the hair, and the follicles remain intact underneath the skin. The same goes for waxing. 

The shaved hair strand may grow inside the skin rather than outside and form a lump.
