What to Know about Scalp Acne

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Scalp acne encompasses a range of conditions, each with distinct clinical features and treatment requirements. Understanding the underlying causes and appropriate treatment options is crucial for effective management. Further research and clinical awareness are needed to improve outcomes for individuals affected by this often-overlooked condition.

By recognizing the different types of scalp acne and their respective treatments, healthcare providers can offer more targeted and effective care, ultimately improving the quality of life for those affected.

Scalp acne, though less commonly discussed than facial acne, can be a significant source of discomfort and distress. It encompasses a variety of conditions, each with unique characteristics and treatment approaches. This article aims to provide a comprehensive overview of scalp acne, its types, causes, and potential treatments.

Types of Scalp Acne

Acne Conglobata of the Scalp

Acne conglobata (AC) is a severe form of nodulocystic acne that can affect the scalp. It is characterized by nodulocystic lesions, interconnecting abscesses, and scars. Although AC typically appears on the trunk, it can also manifest on the scalp, presenting unique clinical and trichoscopic features that differentiate it from other scalp conditions1.

Acne Inversa

Acne inversa, also known as hidradenitis suppurativa, is a chronic inflammatory disorder affecting sebaceous and terminal hair follicles. It can involve the scalp, presenting with perifolliculitis and abscesses. The severity of acne inversa can range from a few lesions to widespread, disabling disease2.

Scalp Pustules Due to Corynebacterium acnes

Scalp pustules can be caused by Corynebacterium acnes, often misdiagnosed as staphylococcal folliculitis. This condition is marked by discrete, turgid pustules predominantly on the posterior and lateral scalp. Treatment typically involves prolonged tetracycline therapy3.

Chronic Non-Scarring Folliculitis

This condition involves recurrent follicular pustules on the scalp without necrosis or residual scarring. It predominantly affects males aged 20-40 and is often associated with Propionibacterium acnes. Oral low-dose tetracyclines can provide symptomatic relief4.

Acne Keloidalis

Acne keloidalis, also known as folliculitis keloidalis, is characterized by small, firm papules that can coalesce into keloid-like plaques. It primarily affects the nape of the neck but can also appear on the scalp, particularly in individuals undergoing immunosuppressive therapy6 9.

Causes and Contributing Factors

Microbial Flora

The microbial flora of the scalp, including Propionibacterium acnes and Corynebacterium acnes, plays a significant role in the development of scalp acne. These bacteria can induce inflammation and contribute to the formation of pustules and nodules5 10.

Hormonal Influence

Hormonal changes, particularly increased androgen levels, can stimulate sebaceous gland activity, leading to the overproduction of sebum and subsequent acne formation. This is a common factor in both facial and scalp acne7 10.

Inflammatory Response

The body’s immune response to bacterial colonization and other irritants can exacerbate acne conditions. Inflammatory acne results from the host’s reaction to follicular inhabitants like Propionibacterium acnes7 8.
