Suffering from scalp acne? This guide explores effective treatments for scalp acne, including over-the-counter and prescription options.We'll also delve into the common causes, such as product buildup, hormonal imbalances, and friction, and provide practical prevention tips. Learn how to identify different types of scalp acne and when to seek professional help from a doctor.
What is Scalp Acne
Scalp acne, much like acne on the face or body, is a common skin condition that occurs when hair follicles become clogged with oil, dead skin cells, and bacteria. This can lead to inflamed, sometimes painful bumps and pimples on the scalp. These pimples can range from small, whitehead-like bumps to larger, inflamed cysts. Scalp can be itchy, tender, and sometimes even painful, especially when aggravated by brushing, combing, or wearing headwear. It's important to distinguish scalp acne from other scalp conditions like folliculitis, which is an infection of the hair follicle, or seborrheic dermatitis, a chronic skin condition that causes scaly patches and redness. While scalp acne can occur on any part of the scalp, it is often found along the hairline, at the nape of the neck, and behind the ears.
Types of Scalp Acne
Understanding the specific type of scalp acne you're experiencing can help determine effective treatment. While all forms involve inflammation of hair follicles, they differ in severity and presentation.
Acne Necrotica Miliaris
Acne necrotica miliaris presents as small, itchy, pus-filled bumps that often crust over. These bumps can be painful and may leave small scars after healing. This type of scalp acne is often found in clusters and can be persistent.
Subtypes of Acne Necrotica Miliaris
While not always categorized into distinct subtypes, acne necrotica miliaris can vary in presentation based on the depth and severity of inflammation.
Superficial Acne Necrotica Miliaris
This involves more superficial inflammation and tends to heal with less scarring.
Folliculitis Decalvans
Folliculitis decalvans is a more severe form of scalp acne that leads to scarring and permanent hair loss. It is characterized by inflamed, pus-filled bumps that group together, often forming patches of baldness. This condition requires prompt medical attention to prevent further hair loss.
Progression of Folliculitis Decalvans
Folliculitis decalvans can progress slowly or rapidly, with periods of remission and exacerbation. Early diagnosis and treatment are crucial to minimizing hair loss.
Early Stage Folliculitis Decalvans
This stage involves small, inflamed bumps and pustules.
Dissecting Cellulitis of the Scalp
Dissecting cellulitis of the scalp, also known as perifolliculitis capitis abscedens et suffodiens, is a chronic, inflammatory condition that affects the scalp and can lead to scarring and hair loss. It is characterized by painful, interconnected abscesses and sinus tracts that drain pus. This condition is requires aggressive medical treatment.
Symptoms of Dissecting Cellulitis
Symptoms include painful, deep-seated nodules, pus drainage, and scarring. Early diagnosis and treatment are essential to prevent permanent hair loss.
Advanced Dissecting Cellulitis
This stage involves extensive interconnected abscesses and significant scarring.
Type of Scalp Acne | Characteristics | Severity |
Acne Necrotica Miliaris | Small, itchy, pus-filled bumps that often crust over. | Mild to Moderate |
Folliculitis Decalvans | Inflamed, pus-filled bumps that group together, leading to scarring and hair loss. | Moderate to Severe |
Dissecting Cellulitis of the Scalp | Painful, interconnected abscesses and sinus tracts that drain pus, leading to scarring and hair loss. | Severe |
Causes of Scalp Acne
Hormonal Imbalances
Fluctuations in hormones, particularly androgens like testosterone, can stimulate sebum production. This excess oil may clog hair follicles, potentially leading to scalp acne. Hormonal imbalances triggered by puberty, menstruation, pregnancy, and conditions like polycystic ovary syndrome (PCOS) can also contribute to breakouts. Even discontinuing birth control pills can sometimes lead to a temporary hormonal shift and increased scalp acne.
Androgens and Sebum Production
Testosterone's Role
The Link Between DHT and Acne
Dihydrotestosterone (DHT), a derivative of testosterone, plays a significant role in scalp acne. It binds to receptors in the sebaceous glands, increasing sebum production and making individuals more susceptible to clogged pores and inflammation.
Poor Scalp Hygiene
Infrequent shampooing may allow sweat, dirt, and oil to accumulate on the scalp, creating a potential breeding ground for bacteria and contributing to acne. Not rinsing shampoo and conditioner thoroughly may also leave residue that can clog pores.
The Importance of Regular Washing
Frequency and Technique
Choosing the Right Shampoo
Washing your hair regularly, especially after sweating heavily, is crucial for preventing scalp acne. Focus on gently cleansing the scalp rather than just the hair strands. Choose a gentle, non-comedogenic shampoo that won't clog pores.
Product Buildup
Using heavy styling products like gels, mousses, and pomades may contribute to clogging hair follicles and potentially lead to acne. Similarly, not washing your hair frequently enough after using these products can exacerbate the problem.
Comedogenic Ingredients to Avoid
Silicones, Oils, and Waxes
Checking Product Labels
Be mindful of comedogenic ingredients in hair products, such as certain silicones, oils, and waxes. Look for products labeled "non-comedogenic" or "oil-free" to minimize the risk of pore-clogging.
Stress and Diet
While not a direct cause, stress can exacerbate acne by influencing hormone levels. Similarly, a diet high in refined carbohydrates and sugary foods can contribute to inflammation and potentially worsen acne breakouts.
The Gut-Skin Connection
Impact of Inflammation
Dietary Considerations for Clear Skin
Emerging research suggests a link between gut health and skin health. A balanced diet can promote a healthy gut microbiome and reduce inflammation, potentially benefiting skin conditions like acne.
Friction and Pressure
Wearing tight hats, helmets, or headbands may create friction and trap heat against the scalp, potentially leading to irritation and acne.Similarly, constantly touching or picking at the scalp can introduce bacteria and worsen existing breakouts.
Avoiding Tight Headwear
Minimizing Scalp Irritation
Keeping Hands Off Your Scalp
Cause | Effect |
Tight Hats/Helmets | Friction and trapped heat |
Headbands | Pressure and irritation |
Touching/Picking | Introduction of bacteria |
Choosing breathable headwear and avoiding excessive touching or picking at the scalp can help prevent acne mechanica, a type of acne caused by friction and pressure.
Effective Treatments for Scalp Acne
Dealing with scalp acne can be frustrating, but thankfully various treatments are available to help manage and clear breakouts. These treatments range from over-the-counter options to prescription medications, catering to different severities and types of scalp acne.
Over-the-Counter Treatments
For milder cases of scalp acne, over-the-counter (OTC) products can sometimes be an effective first line of defense. These are readily available and may often provide relief without the need for a doctor's visit. Be sure to follow product instructions carefully and discontinue use if irritation occurs.
Salicylic Acid
Salicylic acid is a beta-hydroxy acid (BHA) that may help exfoliate the skin, unclog pores, and reduce the likelihood of new pimples forming. Look for shampoos, cleansers, or leave-in treatments containing salicylic acid. Brands like Neutrogena and CeraVe offer products that contain this ingredient.
Benzoyl Peroxide
Benzoyl peroxide is known to kill acne-causing bacteria and may help reduce inflammation. It's available in various concentrations, and it's often found in washes and creams. PanOxyl and Clean & Clear are among the brands that offer benzoyl peroxide products. Start with a lower concentration to minimize potential dryness or irritation.
Ketoconazole Shampoo
Ketoconazole is an antifungal agent that may help in managing scalp acne associated with fungal overgrowth, such as Malassezia folliculitis (fungal acne). Nizoral is a common brand of ketoconazole shampoo. While effective, it's important to use it as directed, as overuse can lead to dryness.
Coal Tar Shampoo
Coal tar shampoo may help slow down the rapid growth of skin cells on the scalp, potentially reducing scaling and inflammation. This can be helpful for scalp acne associated with dandruff or seborrheic dermatitis. T/Gel is one of the brands of coal tar shampoo. Be aware that coal tar can have a strong odor and may stain light-colored hair.
Prescription Treatments
If over-the-counter treatments prove ineffective, a doctor may prescribe stronger medications to address more persistent or severe scalp acne.
Topical Antibiotics
Topical antibiotics, such as clindamycin or erythromycin, may help reduce inflammation and kill bacteria on the scalp. These are typically prescribed in the form of solutions, lotions, or gels.
Oral Antibiotics
For more severe or widespread scalp acne, oral antibiotics like doxycycline or minocycline may be prescribed. These medications help to control bacterial growth from within. It's important to complete the full course of antibiotics as prescribed, even if symptoms improve.
Retinoids
Retinoids, derived from vitamin A, are powerful medications that may assist in unclogging pores, reducing inflammation, and normalizing skin cell turnover. Topical retinoids, such as tretinoin, are sometimes considered for managing scalp acne. Adapalene is another retinoid that can be helpful. These medications can initially cause dryness and irritation, so it is important to follow your doctor's instructions.
Combining Treatments
Sometimes, a doctor may recommend combining different treatments for optimal results. For example, they might suggest using a medicated shampoo alongside a topical antibiotic or retinoid.
Important Considerations for Prescription Treatments
It's crucial to follow your doctor's instructions carefully when using prescription medications. Be aware of potential side effects and report any concerns to your doctor. Pregnant or breastfeeding individuals should consult their doctor before using any prescription acne medications.

Preventing Scalp Acne
General Scalp Hygiene
Wash Your Hair Regularly
Regularly washing your hair helps remove excess oil, sweat, and product buildup that can clog pores and contribute to scalp acne. Aim to shampoo every 1-3 days, or more frequently if you have oily hair or engage in activities that cause excessive sweating. However, avoid over-washing, as this can strip the scalp of its natural oils, leading to dryness and irritation, potentially exacerbating acne. Finding the right balance for your hair type is key.
Choosing the Right Shampoo and Conditioner
Sulfate-Free Options
Consider using sulfate-free shampoos, as sulfates can be harsh and drying, potentially irritating the scalp and worsening acne. Look for shampoos specifically formulated for acne-prone skin or those containing ingredients like salicylic acid or ketoconazole.
Choose the Right Hair Products
Be mindful of the hair products you use, as some can contribute to scalp acne. Avoid heavy, oily products like pomades, waxes, and some conditioners, which can clog pores. Opt for lighter, water-based products that are less likely to cause breakouts. Look for products labeled "non-comedogenic" or "oil-free."
Ingredients to Avoid
Silicones, Mineral Oil, and Petroleum
Certain ingredients like silicones, mineral oil, and petroleum can create a barrier on the scalp, trapping oil and sweat and leading to clogged pores. Check the ingredient list of your hair products and avoid those containing these potentially problematic ingredients.
Lifestyle Adjustments
Avoid Tight Hairstyles
Tight hairstyles like braids, cornrows, and ponytails can trap sweat and oil against the scalp, increasing the risk of acne. Opt for looser hairstyles that allow your scalp to breathe. If you frequently wear hats or helmets, ensure they are clean and well-ventilated to minimize sweat and friction.
Protective Hairstyles and Scalp Health
Maintaining Cleanliness and Allowing the Scalp to Breathe
If you prefer protective hairstyles, ensure you maintain proper scalp hygiene by cleansing regularly and allowing your scalp to breathe between styles. Avoid keeping protective styles in for extended periods, as this can increase the risk of scalp irritation and acne.
Manage Stress
Stress can trigger hormonal fluctuations that contribute to acne breakouts. Practice stress-management techniques like yoga, meditation, deep breathing exercises, or spending time in nature. Prioritizing sleep and relaxation can also help regulate hormones and reduce stress-related acne.
