Scarring alopecia results in an irreversible hair loss due to an inflammation of the scalp (primary), or an accident (secondary).
Hair follicles are permanently destroyed and can only be treated with surgical or cosmetic solutions.

How to identify scarring alopecia?

Scarring alopecia is defined as hair loss on one or more areas of the scalp. An inflammation is the cause of some scarring alopecia and often results in red patches on the scalp. The hair follicle is destroyed and replaced by a fibrous scar, giving the skin a smooth and shiny appearance.
