Are scarring alopecias the only forms of alopecia that result in permanent damage to the hair follicle? if so is Androgenetic Alopecia scarring or non-scarring? Also, is hair loss due to vitamin/iron deficiencies and/or hypothyroidism a scarring or non-scarring form of alopecia? If so then is it theoretically possible to regrow hair years after losing them to these conditions even if it is not yet known how to do so?
Scarring alopecia (otherwise known as cicatricial alopecia) is a hair loss condition caused by an underlying medical issue that causes “scarring” of the hair follicles and the skin around it, as the name implies. It is is generally not treatable with a hair transplant procedure.
According to WebMD, some examples include “dissecting cellulitis, eosinophilic pustular folliculitis, follicular degeneration syndrome (previously called ‘hot comb’ alopecia), folliculitis decalvans, lichen planopilaris, and pseudopelade of Brocq, to name a few. Scarring alopecia may also be part of a much larger condition such as chronic lupus erythematosus, where many organs of the body can be affected.”
Androgenic alopecia is NOT scarring alopecia. Androgenic alopecia is genetic, where the follicles are genetically programmed to “die” after a certain period of time (no scarring).
Vitamin/iron deficiency or hypothyroidism can cause hair loss as a side effect from the underlying medical issues, but there is no scarring involved. In general, scarring alopecia is permanent; however, for many patients we have found a good cosmetic solution with Scalp MicroPigmentation (SMP).
