Folliculitis is typically caused by an infection in the hair follicles of the scalp or on areas of the body that have been shaved. The condition is mostly caused by staph bacteria (Staphylococcus aureus). Folliculitis can also be caused by inflammation from ingrown hairs, viruses, or fungi.
Folliculitis results in small red bumps or pimples on the skin, which you may know as “razor burn” or “razor rash.” The bumps may appear the shade of your skin tone or darker if you have Black or Brown skin.
Shaving, tight clothing, and combining heat and sweat are typical sources of folliculitis. Folliculitis can affect people of all ages, but certain factors may increase your chance of getting this condition.

Approximately 20% of people will get hives in their lifetime. Hives, also called “urticaria,” are raised, itchy, red, or skin-tone welts. They turn white when you press their center. Hives can appear anywhere on the body, and people of all ages get them.
Hives are usually similar in color to your skin tone. Sometimes, they may be slightly lighter or darker, depending on what’s causing them. Because of their common lack of pigment, hives on darker skin can be more difficult to identify.
Hives can be triggered by things such as pollen or insect bites and even some medications. They can be linked to viral or bacterial infections as well as autoimmune diseases.
Hives are generally not serious unless accompanied by a more systemic allergic reaction. Seek urgent medical attention if you experience symptoms of anaphylaxis.

BCC is the most common form of skin cancer. BCCs are abnormal growths that form in the skin’s basal cell layer. They often appear as one small and shiny red bump, and they can look like an open sore. They may also appear as brown or glossy black bumps on darker skin.
Bowen’s disease is an early form of skin cancer. It appears on the surface of the skin and is also referred to as “squamous cell carcinoma in situ.” Bowen’s disease may appear as a red scaly patch, which may ooze, crust over, or itch.
