Non-Scarring vs. Scarring
Non-scarring has an effect on both males and females in which hair follicles are preserved with potential hair regrowth. Examples of non-scarring hair loss include: androgenetic alopecia, which becomes more common as we age; alopecia areata, a type of patchy hair loss in children and adults; telogen effluvium, caused by significant shifts in physical or emotional health and changes in medication; and trichotillomania, caused by individuals pulling out their own hair.
Scarring occurs when the scalp has been inflamed making it harder for hair to regrow. Examples of scarring hair loss includes discoid lupus erythematosus, folliculitis decalvans and lichen planopilaris and frontal fibrosing alopecia.
Restoring hair growth can be treated with a board certification dermatologist's guidence and may include supplements including Vitamin D, a hair transplant that can help restore hair density, medications including Topical minoxidil and platelet-rich plasma (PRP) in which the patient's own blood is drawn and injected into the scalp.
