What should you know about Demodex mites in human hair?

Hair follicles are openings in the skin from which hairs grow. Demodex may be found in these follicles or nearby sebaceous glands, so cutting or removing the visible hair does not address every possible source of irritation. A positive finding also needs context, because mites can be present without causing disease.

Itch, redness, flakes, bumps or a crawling sensation can come from several causes, including dandruff, contact dermatitis, folliculitis and psoriasis. Hair shedding can follow inflammation or breakage and does not by itself identify Demodex as the cause. A clinician can inspect both the scalp and the hair-care routine.

Choose a gentle shampoo, rinse well and avoid scratching, tight hairstyles and heavy products on irritated skin. Clean brushes and pillowcases regularly, and avoid sharing personal hair tools. Do not use pesticides, kerosene or concentrated essential oils on skin or hair.

Persistent symptoms deserve a dermatology review. Depending on the diagnosis, a clinician may suggest a [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/) or another therapy. Use medicated products only as directed, since the right treatment depends on whether mites, inflammation, infection or product sensitivity is involved.

Seek an assessment for ongoing scalp inflammation, painful pustules, thick crusts, patchy hair loss or worsening scale. Prompt care is sensible when the skin is hot, tender, draining or rapidly changing, because infection or another inflammatory condition may need treatment.

Ask whether the problem is in the follicles or hair shaft, what other diagnoses should be considered, whether a sample is useful, and how to continue washing your hair during treatment. Mention dyes, relaxers, extensions, oils and recent changes in products.
