How Do You Get Demodex Mites?

Demodex are tiny organisms associated with hair follicles and oil glands, especially on the face, eyelashes and scalp. They can be part of the normal skin environment and are not a sign that someone is dirty. Symptoms may become more noticeable when the skin barrier is irritated, oil production changes, or local inflammation makes the mites and their debris harder for the skin to tolerate.

Redness, rough patches, itching, scaling, follicle bumps and eyelid irritation can have many explanations. Facial flushing and sensitivity may overlap with [Rosacea](/conditions/rosacea/), while scalp flaking may have a different cause entirely.

Cleanse gently, avoid sharing towels or eye makeup, replace old eye cosmetics, and wash pillowcases and face cloths regularly. Do not try to sterilise the skin or apply household pesticides. These actions can injure the skin without addressing the reason for the symptoms.

If itching, redness or scaling continues, a dermatologist can examine the affected sites and decide whether testing is useful. Mention recent product changes, eye symptoms, scalp shedding and any medicines that affect immunity. For scalp symptoms, ask whether [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/) fits the diagnosis.

Get prompt help for eye pain, light sensitivity, blurred vision, marked eyelid swelling, pus, rapidly spreading redness or fever. Book an assessment for recurring facial flares, persistent scalp irritation, new bald patches or symptoms that do not settle with gentle care.

Could another skin condition explain these symptoms? Which areas should be examined? Do I need testing, and which shared items or cosmetics should I replace?
