Symptoms
Acrodermatitis enteropathica
Hair Loss Patterns
The primary symptom of alopecia areata is the sudden onset of hair loss, typically in small, round or oval patches. These patches are usually smooth and can vary in size.
The condition can progress to more extensive hair loss, such as:
- Initial Signs: Small, round bald patches.
- Progression: Additional patches may develop, sometimes merging to form larger areas of hair loss.
- Severe Cases: Complete loss of scalp hair (alopecia totalis) or body hair (alopecia universalis).
Associated Sensations
Some individuals may experience sensations such as itching, tingling, or burning in the areas where hair loss occurs. These sensations often precede the hair loss.
Nail Changes
Approximately 10-20% of people with alopecia areata also exhibit changes in their nails. Common nail changes include pitting (small dents), ridging, and brittleness. In severe cases, the nails may become rough and develop a sandpaper-like texture.
