Here's Why You're Getting Pimples on Your Scalp (And What to Do)

Apparently acne shows up wherever it pleases.

One of the least comfortable places to get acne is on your scalp, but it's really no different from any other area of your body that may experience breakouts, right? Like your standard pimples, scalp acne can be caused by a mixture of oil and dead skin cells that get stuck in hair follicles. But unfortunately, the cause of scalp acne isn't always as straightforward as that. We talked to two dermatologists about how to determine what are actually pimples on your scalp versus what are bumps caused by severe dandruff—which can cause pimple-like spots on your scalp.

Meet the Expert

  • Nava Greenfield, MD, is a medical dermatologist at Schweiger Dermatology Group in NYC. Her work has led to contributions in publications such as the Journal of Dermatological Treatment.
  • Neal Schultz, MD, is a New York City dermatologist with more than 30 years of experience. He's also the developer of the brand Beauty Rx, a skincare line developed to give dermatologist-office-level results at home.

What Causes Scalp Acne?

Greenfield explains, "Blemishes on the scalp can be caused by a wide range of skin diseases, some of which are very benign and others that are more serious. The most common blemishes on the scalp that I see are from cysts on the scalp, scalp acne, and from seborrheic dermatitis, or dandruff." Luckily, the treatments for these types of scalp blemishes are simple. Greenfield says, "These conditions are easily treatable with either a simple excision (for a cyst) or anti-dandruff and anti-acne medications."

Things like travel, stress, and lack of sleep can also cause scalp acne, Schultz adds. When your cortisol levels rise, your body is more likely to produce oil. This excess oil can cause acne.

If you're finding frequent breakouts on your scalp, there's a singular wise method of treatment, as Greenfield puts it: "Bottom line: Check with your dermatologist. A dermatologist can help you categorize the types of breakouts you're seeing and figure out the best treatment... It's important to have a dermatologist evaluate any blemishes because other more serious diseases, like cutaneous lupus and lichen planopilaris, can also result in spots on the scalp. These can be treated as well but require closer attention by your dermatologist."

Lather, Rinse, Repeat

If you are prone to oily hair, scalp acne could be caused by an excess of oil. You'll want to be sure you're washing with water every other day, even if you skip the shampoo—especially after workouts. Schultz agrees that washing your hair to prevent excess oil is super important. Look for shampoos with ingredients like salicylic acid, coal tar, or cortisone. Salicylic acid and coal tar are meant to help reduce dandruff and oil production on your scalp, while cortisone helps treat inflammation and dryness. A shampoo with cortisone is normally only available in the doctor's office, so be sure to check with your dermatologist.

If you prefer your regular shampoo because it's volumizing or makes your hair silky soft, feel free to go in for a second shampoo after using an acne-formulated shampoo.

We love this product for clearing buildup and soothing itchiness. Plus, its price for the quality can't be beat.

Sachajuan's Scalp Shampoo is fantastic for removing dandruff and soothing an irritated scalp, thanks to ingredients such as Piroctone Olamine and Climbazole.

Don't Pick

If you must touch a pimple on your scalp, avoid picking and scratching at it as much as possible. Popping or scratching the spot can allow bacteria to enter it, delaying healing time and further irritating it.

Even with dandruff, you can get a rash that looks like pimples. Even though they aren't technically acne, they can still itch like crazy. "They get even crustier when you pick at them, which everybody does," Schultz says. The same rule for pimples goes for this rash, too: Hands off.

If the pimple is super itchy, try gently pressing on it instead. Adding some pressure can help take away the itch, plus it doesn't open up the pimple.

Remember to Exfoliate

Using an exfoliating scalp treatment once a week can help clear your scalp of any excess dry skin. Tea-tree oil, as an antibacterial ingredient, is an exception to other oils and can also be used to treat acne (as you would on your face) by adding a drop to your shampoo—but a little goes a long way here. Too much oil may make your acne worse (more on that later).

Although exfoliating helps remove excess oil and dry skin, it's better to stick to chemical exfoliants (like salicylic or glycolic acid) than physical exfoliants. "The problem on the scalp is already irritation, and I'm afraid that a physical exfoliator is going to cause too much irritation," Schultz says.

Key Ingredients

Glycolic acid is an alpha-hydroxy acid that loosens bonds between dead skin cells. It helps stimulate collagen production and acts as a humectant, attracting moisture to the skin.

If you feel you must use a physical exfoliant, stick to something gentle, and only use it when your scalp isn't seriously irritated.

Briogeo's exfoliating scalp revival shampoo works for scalps irritated by oil or dryness. All hair types—straight, wavy, curly, and coily—can benefit from this scrub.

Avoid Adding Oils

Avoid using thick or greasy hair products that will leave a film behind. Keep hair repair treatments and deep conditioning masks away from the scalp. Instead, use them to treat damaged ends, as these can lend excess oil to the roots—the same goes for your everyday conditioner.

Many people with acne or severe dandruff suffer from an excess of oil on the scalp. Even though oils are great for moisturizing your hair, they can cause buildup on your scalp: "You don't want to feed fuel to the fire; you don't want to put oil on acne," Schultz says.

Don't Be Afraid to Use Acne Products

You can treat mild scalp acne with most any over-the-counter acne product on the market, although you may want to avoid products containing benzoyl peroxide because they can lead to bleaching or discoloration of hair. A light moisturizer containing salicylic acid is a good option for small spots on your scalp, and it won't bleach your hair either. But if your acne continues or gets really severe, consider talking to a dermatologist about an oral or topical medication that might work better for you.

  • Can you pop scalp pimples?

    When it comes to preventing pimples on your scalp, the same rules apply here as on your face, namely keeping your hands off. Picking and prodding at blemishes will only make them more numerous. Additionally, as with any other area of acne, scalp breakouts can potentially be hormonal. In that case, a visit to the dermatologist, as per Greenfield's suggestion, is best.

  • Can scalp pimples cause hair loss?

    The buildup that clogs your follicles and leads to scalp acne can, in turn, potentially lead to hair loss. "Infrequent shampooing and product buildup from dry shampoo, leave-ins, or improper rinsing can really block the follicle opening," trichologist Shab Reslan told us. "Over time this causes the follicle to become inactive and create a permanent effect." Dermatologist Joshua Zeichner added: "When hair follicles are not working the way that they should, hairs may grow thin or fall out."

  • Will my hair grow back after scalp pimples?

    Yes—as long as the follicle is cleared and still intact. Make an appointment with your dermatologist if you're concerned about your hair re-growth post-pimple.
