Cicatricial alopecia occurs when inflammation damages the hair follicles, leading to irreversible scarring.
There are several possible causes of this inflammatory response, including:
Autoimmune Disorders: Conditions such as lichen planopilaris and discoid lupus erythematosus can trigger an autoimmune reaction that targets the hair follicles, resulting in scarring alopecia.
Infections: Fungal or bacterial infections of the scalp can cause inflammation and damage to the hair follicles, leading to scarring alopecia if left untreated.
Trauma or Injury: Physical trauma, burns, or other injuries to the scalp can disrupt the hair follicles and trigger an inflammatory response that leads to scarring.
Genetic Predisposition: Some individuals may have a genetic predisposition to developing cicatricial alopecia, although the exact mechanisms are not fully understood.
