The clinical course is highly variable and unpredictable. Hair loss may be slowly progressive over many years, without symptom, and unnoticed for long periods.

The inflammation that destroys the follicle is below the skin surface and there is usually no "scar" seen on the scalp. Affected areas of the scalp may show little signs of inflammation, or have redness, scaling, increased or decreased pigmentation, pustules, or draining sinuses.
