Scalp Flaking: Causes, Treatments, and Medication Links

When your scalp flakes, it’s not just about dry skin. scalp flaking, a visible shedding of skin cells from the scalp, often linked to dandruff or seborrheic dermatitis. Also known as dandruff, it’s more than an annoyance—it can be a sign your body is reacting to something inside or outside your skin. Many people assume it’s just dryness or poor hygiene, but it’s often tied to inflammation, fungal overgrowth, or even the medications you’re taking.

seborrheic dermatitis, a common skin condition that causes oily, scaly patches on the scalp, face, and chest is one of the top culprits behind persistent flaking. It’s not contagious, but it can flare up when you’re stressed, sick, or taking certain drugs. Beta-blockers, for example, are known to worsen skin conditions like psoriasis and seborrheic dermatitis. If you started a new heart medication and noticed your scalp getting worse, that’s not a coincidence. antifungal shampoos, products containing ketoconazole, selenium sulfide, or pyrithione zinc that target the yeast linked to scalp flaking are often the first line of defense—but they don’t fix the root cause if a medication is triggering it.

Scalp flaking can also be a side effect of drugs that alter your immune system, hormone levels, or skin oil production. Isotretinoin for acne, lithium for bipolar disorder, and even some antidepressants have been linked to dry, flaky skin. If you’ve been using the same shampoo for months and nothing changes, it’s worth asking: Could this be a drug reaction? You might need to switch shampoos, adjust your meds, or treat an underlying condition like psoriasis—which itself can be triggered by beta-blockers or other heart medications.
