Cicatricial alopecia is primarily caused by inflammation that damages the hair follicle, although the damage may also be caused by a trauma such as a burn or serious infection. The inflammation could involve different types of cells, including lymphocytes, natural killer cells, or a combination of cell types.
Can scarring alopecia be treated?
Though hair loss due to scarring alopecia is permanent and cannot be reversed once scarred, it can be treated to help prevent further hair loss and scarring.
How do you get rid of scarring from alopecia?
Scarring alopecias that involve mostly lymphocyte inflammation of hair follicles, such as lichen planopilaris and pseudopelade, are generally treated with corticosteroids in topical creams and by injection into the affected skin. In addition, antimalarial and isotretinoin drugs may be used.

Scarring alopecia generally starts with the appearance of small patches of hair loss that may grow larger over time. For some, there are no other noticeable symptoms, while in others the patches may become inflamed and cause itching and pain.
How can you tell the difference between scarring and Nonscarring alopecia?
In non-scarring alopecia, hair follicles are preserved with potential for hair regrowth. In scarring alopecia, the hair follicle is irreversibly destroyed due to destruction of stem cells in the bulge area of the outer root sheath, and replaced by fibrous scar tissue, leading to permanent hair loss.
Is Cicatricial alopecia reversible?
Secondary cicatricial alopecia is also irreversible, though destruction of the hair follicle is incidental to a non-follicle-directed cause, such as thermal burns, metastatic cancer, trauma or radiation.
