Pimples on the scalp is a bacterial folliculitis, Staphylococcus Aureus. There are two categories for the scalp: superficial and deep. Superficial is the most common form of folliculitis seen by a board certified Trichologist. It is seen as a tender or painless pustule, that heals without scarring in most cases. There are some exceptions. I most commonly see the contributing cause from Traction Alopecia around the outer-perimeter of the scalp.

Folliculitis starts when hair follicles are excessive tension, damaged by friction from clothing, occlusion or blockage of the follicle, physical injury, chemical irritation or infection. Favorite sites of involvement include the scalp, neck, trunk, buttocks, and extremities.

There are other types of folliculitis:
•   Deep Folliculitis: infection extends deep into the follicle. It affects either the entire follicle or the deeper portion of the follicle, with increased inflammation, and erythma (redness), also furuncles and carbuncles are more pronounced, are painful and may permanent damage and scarring.
•   Gram-Negative Folliculitis: a deep folliculitis that sometimes develops in people receiving long term antibiotic treatment for acne.
•   Hot Tub Folliculitis: often seen where spa sanitation is at fault.
Examples include: contaminated whirlpools, hot tubs, water slides and physiotherapy pools. Is manifested within 6-72 hours after exposure.
•   Fungal Folliculitis: classified as tinea capitis (scalp), tinea barbae (beard), tinea corporis (trunk), tinea cruris (groin) and tinea pedis (feet). Tinea capitis or ringworm of the scalp, involves: black dot, gray patch, favus and kerion.
•   Viral Folliculitis: caused by the herpes simple virus, and appears as clustered vesicles, (small circumscribed elevation of the skin containing serum), often progress to form pustular of ulcerated lesions, and eventually a crust.
•   Parasitic Folliculitis: small pathogens that burrow into the hair follicles to live there or lay their eggs. Mites such as Demodex folliculorum reveal eruptions of the scalp with or without pus.
On goes the list……
