An itchy scalp can be annoying and sometimes persistent. The main causes typically fall into a few categories:
- Dandruff (Seborrheic Dermatitis)
- Flaky, often greasy patches accompanied by itching. Caused by overgrowth of yeast on the scalp or excess oil production.
- Psoriasis
- Chronic autoimmune condition that leads to thick, scaly, silvery patches. Can be itchy and sometimes painful.
- Dry Scalp
- Often caused by cold weather, harsh shampoos, or frequent washing, leading to tightness, flaking, and itching.
- Allergic Reactions / Contact Dermatitis
- Triggered by hair dyes, shampoos, conditioners, or styling products. Redness, bumps, and itching are common.
- Head Lice
- Tiny parasites that feed on blood, causing intense itching and sometimes visible nits (eggs) on hair strands.
- Fungal Infections (Tinea Capitis)
- Ringworm of the scalp can cause itchy, scaly patches and sometimes hair loss.
- Other Medical Conditions
- Certain systemic issues like thyroid problems or stress can exacerbate scalp itching.
