Scalp Acne: Does It Cause Hair Loss? Why Won’t It Go Away?

Scalp acne can be extremely frustrating—it often recurs in hot and humid weather and leaves acne scars on the scalp, nape of the neck, and the hairline. What exactly causes scalp acne, and can it lead to hair loss in severe cases? How do dermatologists treat it? What ingredients should you look for in shampoos to prevent it? This article has all the answers, so you can finally say goodbye to scalp acne!

Is This Really Scalp Acne?

Scalp acne generally falls into two categories. Grab a mirror and take a closer look at your scalp.

One type appears as one or two occasional pimples on the scalp, often near areas with minor damage—such as scratches from fingernails or brushes—or near the hairline at the nape. These are usually larger, itchy, and painful, and may or may not be filled with pus. They tend to heal on their own without treatment, even if the pus is squeezed out. Dermatologists consider this type to be a form of acne caused by occasional follicle blockage or by a hot and humid scalp environment that encourages bacterial overgrowth and inflammation. These don’t usually require treatment.

The second type consists of small, clustered pimples that are red and possibly pus-filled. Though they may not be painful, they tend to recur. Without anti-inflammatory shampoos or topical ointments, they are unlikely to heal on their own.

Symptoms of Scalp Acne

Scalp acne can cause itching, mild pain, and redness. Mild cases appear as raised papules or pustules, with or without pus, and may heal naturally. More serious cases may develop nodules or cysts that damage the dermis and leave scars—preventing hair regrowth. Scalp acne may also manifest as bacterial or fungal folliculitis, where small red or pus-filled pimples spread across the scalp. These cases require medication to resolve.

What Causes Scalp Acne?

1. Excessive Oil Production

People with oily or sensitive skin are more prone to scalp acne. The scalp is an extension of your facial skin, so if you have acne-prone facial skin, your scalp is likely similar. Without proper cleansing or exfoliation, dead skin can clog pores, mix with acne bacteria, and cause inflammation, redness, and pain. Oily scalps are also linked to seborrheic alopecia.

2. Sensitive or Dry Scalp

Scalp acne isn’t limited to oily skin types. People with dry, thin, or damaged scalps are also vulnerable. Acne may occur when the skin’s oil barrier is compromised, leading to excessive dryness and triggering immune responses and inflammation. Scratches from nails or brushes can also introduce bacteria. Over-cleansing and using unsuitable shampoos can further damage the scalp’s barrier.

3. Chemical Irritants

Hair dye, bleach, perm solutions, styling sprays, wax, and even temporary color sprays can irritate the scalp, especially if it’s already acne-prone or injured. Avoid hair styling products if you're prone to scalp issues and maintain a clean, dry scalp environment.

4. Allergic or Inflammatory Reactions—Bacterial or Fungal

If your scalp acne keeps recurring, you may have folliculitis. Bacterial folliculitis often occurs when the scalp is injured and worsens with poor hygiene or picking at the acne. If it spreads, it may lead to cellulitis. Fungal folliculitis, which is contagious, can spread through shared items like towels, combs, or hats. If not treated properly, the infection can worsen and potentially lead to permanent hair loss.

Is Scalp Acne Contagious?

Most scalp acne isn’t contagious. However, fungal scalp acne can be, so it’s important to maintain good hygiene and avoid sharing personal items like combs, hats, or scarves.

4

Is Scalp Acne Just an Extension of Regular Acne?

Scalp acne and facial acne both reflect poor skin health and weakened immunity. Excess oil production increases the risk of both. However, scalp and neck acne can also stem from fungal infections. If your scalp acne is recurring, severe, or widespread, avoid using regular acne creams and see a doctor instead. Facial acne products can worsen scalp acne due to different skin environments.

Who Is Most Prone to Scalp Acne?

People with oily skin, athletes, those working outdoors or in hot environments, and service workers who wear hats or helmets are more susceptible. They should wash their hair more frequently to keep the scalp ventilated.

What Are the Consequences of Scalp Acne?

1. Dandruff Like Snowflakes

Scalp acne often signals a disrupted skin turnover cycle. When dead skin clogs pores, dandruff may increase. Dry scalp leads to white flakes, while oily scalp causes larger, yellowish flakes. Scabs from healing acne can worsen dandruff, so sudden dandruff spikes should not be ignored.

2. Large Cystic Pimples

Severe acne can affect deeper skin layers. Popping immature pimples can rupture the pus sac beneath the skin, leading to larger cysts or even more serious infections.

3. Hair Loss

Severe cystic acne can scar the dermis, preventing hair regrowth in affected areas. This results in round bald patches that resemble alopecia areata. An unhealthy scalp environment also weakens hair follicles, increasing the risk of chronic folliculitis and eventual hair loss if left untreated.

How to Treat Scalp Acne

1. Tar-Based Shampoo

Tar-based shampoos reduce excess oil and dandruff, which helps treat scalp acne at its source. However, they may overly dry out normal or dry scalps, worsening dandruff and itchiness. Use sparingly and avoid if you have sensitive or dry skin.

2. Anti-Inflammatory Shampoos

Choose shampoos with ingredients like selenium sulfide, zinc pyrithione, or essential oils such as peppermint, eucalyptus, tea tree, and lavender. These regulate oil production and fight fungi. Sensitive skin types should opt for formulas with simple ingredient lists.

3. Prescription Antibiotic Creams or Solutions

If medicated shampoos don’t help, see a doctor. They may prescribe antibiotic ointments or oral antibiotics. For fungal infections, antifungal creams will be prescribed.

4. Traditional Chinese Medicine (TCM): Herbal Remedies & Acupuncture

If your scalp feels balanced but acne still persists, TCM views scalp acne as related to "damp-heat" and poor internal circulation. Dietary triggers like greasy, spicy, or caffeinated foods contribute to excess heat. Chinese medicine uses herbs and acupuncture to restore internal balance and improve scalp health.

How to Prevent Scalp Acne: 7 Daily Habits

1. Thoroughly Clean Your Scalp

Too much oil and thick keratin buildup can block pores. Wash hair more frequently in summer with oil-control shampoos. In winter, use more hydrating formulas to avoid triggering acne from dryness.

2. Avoid Conditioner Contact with the Scalp

Most conditioners are heavy and can clog pores. Apply only from mid-length to ends. For those with acne near the nape, avoid conditioners and use hair oils on the last 5cm of hair instead.

3. Clean Your Hairbrush Regularly

You use it every day—but do you wash it? Hairbrush bristles collect oil, dead skin, and product residue, which can transfer bacteria back to your scalp. Clean it weekly to prevent buildup.
