Yeast infection on the scalp: causes and care

Yeast and other fungi can thrive when sweat, oil, or occlusive hair products remain on the scalp. Flaking around the hairline, eyebrows, or ears may fit seborrhoeic dermatitis, while tender spots, broken hairs, pus, or areas of hair loss can point to another fungal or bacterial condition. Psoriasis and allergic reactions can also mimic infection. Scratching may cause small wounds and make inflammation worse, so the pattern and hair changes matter to diagnosis.

Wash the scalp as advised for your hair type, rinse products thoroughly, and avoid sharing brushes, hats, pillows, or towels until the cause is clear. Do not scratch, pick scales, or apply household remedies. Because some scalp infections require prescription medicine that reaches the hair roots, arrange an examination rather than relying on a skin cream. Tell the clinician about hair loss, children or pets with similar symptoms, and recent products.

Arrange prompt medical review for spreading scale, painful swelling, pus, broken hairs, patchy hair loss, or symptoms that persist. Seek urgent help for facial swelling, fever, severe tenderness, or rapidly worsening redness. Early assessment is particularly useful when a child has scalp changes or when several household members are affected.

Does this look like yeast, seborrhoeic dermatitis, ringworm, or psoriasis? Do I need a scalp sample? Could treatment affect hair, and how should I prevent spread through hair tools and bedding?
