If Your Scalp Won't Chill Out, It Might Be Seborrheic Dermatitis
What exactly is seborrheic dermatitis?
Dr. Dawn Queen, a board-certified dermatologist, defines this condition as a chronic inflammatory disorder that produces red, flaky patches, especially on the scalp, eyebrows, and around the nose. Dr. Joel Schlessinger, also a board-certified dermatologist and cosmetic surgeon, adds that the medical term essentially refers to severe dandruff, but it can appear anywhere on the body where there’s a high concentration of sebaceous glands. The root cause, explains Dr. Schlessinger, is the excessive proliferation of Malassezia, a species that naturally lives on our skin. This overgrowth leads to flaking, irritation, intense itching, and dry skin. In prolonged cases, the condition can even contribute to hair loss. An often-overlooked aspect is that seborrheic dermatitis isn’t limited to the scalp; it can affect the face, particularly the eyebrow area and the folds beside the nose, where more oil tends to accumulate.

Nevertheless, experts confirm that seborrheic dermatitis can flare up or recur at any time. Dr. Queen emphasizes that the condition can appear at any age and may be diagnosed for the first time in adulthood, even in people who’ve never had such issues before. The disease course is recurrent, alternating between periods of exacerbation and phases of remission. Triggering factors vary and include cold or dry weather, impaired skin barrier function, concurrent illnesses, and emotional stress. In many cases, there’s no clearly identifiable trigger, and symptoms seem to appear out of nowhere. Dr. Joel Schlessinger also notes that the phenomenon known as „cradle cap” in babies is actually a classic form of seborrheic dermatitis.
Origin and triggering factors
If you suspect you’re suffering from seborrheic dermatitis, there are numerous practical and gentle lifestyle modifications that can help manage symptoms. Shab Caspara, a certified trichologist and founder of Caspara Hair Preservation Studio, recommends not letting too much time pass between washes. „Extending the time between washes allows oils and yeast to accumulate, and this buildup leads to inflammation,” she explains. For most people, washing hair every one to two days makes a significant difference. She also suggests lowering water temperature during washing. „Hot water strips the scalp’s natural barrier and can disrupt its microbiome, causing an already reactive scalp to respond even more strongly,” says Caspara. „Lukewarm water is your friend.”
Treatment and routine adjustments for a calm scalp
For Aga Tompkins, a certified trichologist and cosmetician, the best measure is to stop ignoring your scalp in your beauty routine. „Your scalp is skin and needs its own care routine,” she affirms. Both Tompkins and Caspara stress the importance of avoiding harsh scrubbing or picking at flakes. „It may be satisfying in the moment, but damaging an already irritated skin barrier can create additional inflammation,” they explain to clients.
Tompkins also recommends carefully reviewing the ingredients in your scalp care products, similar to how we choose facial products. „When the goal is maintaining a healthy scalp environment, look for ingredients that support hydration, skin barrier function, oil balance, and gentle removal of buildup,” she details. For example, niacinamide is frequently used in scalp formulas to support the skin barrier and help balance sebum, while panthenol and aloe vera contribute to hydration. Acids such as lactic acid can provide mild exfoliation to weaken excessive buildup when needed, and botanical ingredients like green tea, jojoba oil, and tea tree oil are commonly found in these formulations.
