Reason 1 Because the bump is the aftermath. The real problem happens before it.
Every hair grows out through a pore.
Dead skin and oil block that pore. Coarse hair, curly hair, frequent shaving — your skin can't shed them fast enough.
The hair grows up, hits the blockage, and turns sideways. It keeps growing under your skin.
Days later, that's your bump.
So you treat the swelling. The pore stays blocked.
That's why it comes back in the same spot.
