Dry or Flaky Scalp
Dry or flaky scalp is a common condition characterized by the shedding of dead skin cells from the scalp, often accompanied by itching and irritation. While usually not serious, it can be uncomfortable and embarrassing. The condition ranges from simple dryness to more complex skin disorders requiring medical treatment.
⚠️ Seek Medical Care For:
- Severe scalp pain with flaking
- Signs of infection (pus, red streaks, warmth)
- Scalp sores that won't heal
- Sudden hair loss with scaling
- Fever with scalp symptoms
- Swollen lymph nodes in neck
- Spreading rash beyond scalp
- Severe allergic reaction symptoms
Definition and Overview
The scalp, like other skin areas, continuously sheds dead cells. However, when this process accelerates or becomes visible, it results in flaking. Causes range from environmental factors like cold weather to skin conditions like seborrheic dermatitis or psoriasis. Understanding the underlying cause is key to effective treatment.
Dry scalp differs from dandruff, though they're often confused. Dry scalp results from insufficient moisture and produces small, dry flakes, while dandruff (seborrheic dermatitis) involves excess oil production and larger, yellowish flakes. Both conditions can cause itching but require different treatment approaches.
