How does Scalp Acne Cause Bumps?
Scalp acne usually forms in similar way as acne in any other part of the body. The sebaceous or even the oil glands are usually located deep in skin and each oil gland is then connected to a follicle, which is a tiny canal that has a hair.
The oil or even the sebum that is produced by the sebaceous glands flows out through the follicle to skin surface. This assists to lubricate the hair follicles and also the skin. The opening of follicle on skin surface is called a pore.
Acne forms due to a combination of 3 factors

  • Excess oil production.
  • Blocked pores.
  • Inflammation brought about by bacteria.

Acne forms when an overactive sebaceous gland produces excess oil, which might then get trapped within blocked pores. The exact cause of the blocked pores is not indicated. Due to this blockage, the hair follicle might enlarge so as to form a little bump and in time it can rupture, therefore allowing bacteria to reach very deep into tissues and lead to inflammation.
Normal skin bacteria, Propionibacterium acnes (P. acnes) usually multiply within the blocked pores and leads to inflammation of the follicle. Acne is not brought about by bacterial infection but the bacteria might play a role in the development. Whiteheads, painful red bumps, pustules and boils develop due to the pore blockage.
Superficial inflammation leads to pustule formation, while deeper inflammation leads to pimples, and still deeper ones causes cyst formation.
