How to Treat and Prevent Scalp Acne

You’ve probably dealt with a pimple on your face before, but what about on your scalp? Those small, painful bumps you feel when you run your fingers through your hair might be scalp acne. While it’s often hidden under your hair, it can be just as frustrating — sometimes itchy, sometimes sore, and sometimes leading to inflammation or even hair shedding if left untreated.

Here’s what causes scalp acne, how to treat it effectively, and how to prevent it from returning.

What Causes Scalp Acne?

Scalp acne forms when your hair follicles (the tiny openings where each strand of hair grows) become clogged with oil, dead skin cells, and product buildup. Once bacteria or yeast enter the mix, inflammation begins — leading to those painful bumps or pustules.

Here are three reasons why your follicles are not producing healthy hair

Some common causes include:

• Excess oil production: Too much sebum can clog follicles and trap bacteria.
• Product buildup: Heavy oils, conditioners, or styling products that aren’t rinsed properly can block pores.
• Infrequent washing: Skipping wash days allows sweat, dirt, and oil to accumulate.
• Tight hairstyles: Braids, ponytails, or headwraps that pull on the scalp can cause irritation.
• Hormonal changes or stress: These can increase oil production and trigger flare-ups.
• Poor scalp hygiene post-workout: Sweat and friction under hats or headbands can make acne worse.

Is It Product Buildup or Dry Scalp? Here's How to Tell the Difference

How to Treat Scalp Acne

1. Use a Clarifying or Medicated Shampoo
   Choose shampoos with salicylic acid, zinc pyrithione, or tea tree oil to help exfoliate and reduce inflammation. Use 1–2 times a week to deeply cleanse and prevent clogged pores.
2. Cleanse Regularly
   If you’re stretching wash days too long, scalp acne might be your cue to adjust. Washing every 3–7 days (depending on your hair type) helps control oil and bacteria.
3. Use Lightweight, Non-Comedogenic Products
   Opt for scalp oils and leave-ins that won’t clog follicles. If you oil your scalp, massage gently and ensure you wash it out on your next wash day.
4. Avoid Picking or Scratching
   It can be tempting, but picking at scalp acne can worsen inflammation or cause scarring. Instead, soothe the area with gentle care and medicated treatments.
5. Rinse After Sweating
   After workouts, at least rinse or lightly cleanse your scalp. Sweat left to dry can clog pores and worsen breakouts.
6. Try a Scalp Toner or Mist
   Toners with amino acids, thyme, or rosemary help refresh your scalp between washes and control oil production.

How to Prevent Scalp Acne

• Keep your tools clean: Wash your combs, brushes, pillowcases, and bonnets regularly.
• Avoid layering too many products: Stick to what your scalp actually needs — less is often more.
• Massage your scalp regularly: It promotes blood flow and balances oil distribution.
• Avoid tight styles: If you wear braids or weaves, ensure they’re not installed too tightly, and cleanse your scalp while in the style.
• Eat a balanced diet: Nutrient-rich foods can help regulate sebum production and promote scalp health.

When to See a Dermatologist

If your scalp acne persists, becomes painful, or leads to hair loss, it’s best to consult a dermatologist. They may prescribe topical or oral medications to manage more severe cases.
