The scalp is a sensitive area that reacts to both internal and external factors such as genetics, your hygiene routine, the environment, and infections.
While issues like dandruff are common, other problems such as seborrheic dermatitis and folliculitis involve yeast or bacteria. Seborrheic dermatitis causes oily flakes and redness, and folliculitis creates red bumps filled with pus. Since many scalp conditions resemble one another, it is crucial to be diagnosed right in order to get a proper treatment.

Bumps appear on the scalp because of various reasons. Seborrheic dermatitis usually produces greasy yellow flakes that itch. Folliculitis results in small, painful bumps caused by infected hair follicles. Pilar cysts are harmless fluid-filled growths that sometimes become quite noticeable. Psoriasis can form thick patches with shiny, silvery scaling. Understanding these common causes can make it easier to identify what you are experiencing.
