If you regularly get ingrown hairs you probably have thick, curly or coarse hair, or it might just occur with your beard, pubic hair or underarm hair.
Baldeep added: “Harsh shaving is the number one culprit of producing ingrown hair by creating a sharp tip on the end.
“If shaved, plucked or waxed incorrectly, or even if constantly subjected to friction such as rubbing against clothing, an individual or a small number of hairs may form sensitive raised bumps which may then go on to fill with pus.
“This is a sign that the body is reacting to the hair as if it were a foreign body.”
Sometimes however, ingrown hairs are just hair follicles that have naturally become clogged with dead skin or dirt.
