Demodex & Seborrheic Dermatitis

Demodex mites can worsen seborrheic dermatitis and trigger redness, flaking, itching, oily skin, and scalp irritation. Many people treat dandruff for years without realizing mites may be part of the problem. These microscopic mites live in hair follicles and sebaceous glands. When they overgrow, they increase inflammation and weaken the skin barrier. This leads to recurring flare-ups and stubborn scalp symptoms. Understanding the link between Demodex and seborrheic dermatitis helps identify the root cause and supports better long-term treatment for healthier skin and scalp.
