Cicatricial Alopecia (Scarring)
The term "cicatricial alopecia" refers to a diverse group of rare disorders that destroy the hair follicles, replace it with scar tissue, and cause permanent hair loss. The clinical course is highly variable and unpredictable. Hair loss may be slowly progressive over many years, without symptom, and unnoticed for long periods. Or the hair loss may be rapidly destructive within months and associated with severe itching , pain and burning. The inflammation that destroys the follicle is below the skin surface and there is usually no "scar" seen on the scalp. Affected areas of the scalp may show little signs of inflammation, or have redness, scaling, increased or decreased pigmentation, pustules, or draining sinuses.
Cicatricial Alopecia occurs in otherwise healthy men and women of all ages, is not contagious, not hereditary and is seen worldwide.
Traction Alopecia is a form of alopecia, or gradual hair loss, caused primarily by pulling force being applied

Trichotillomania also called hair pulling disorder, is a disorder that involves recurrent, irresistible urges to pull out hair from your scalp, eyebrows, or other areas of your body, despite trying to stop.
Hair pulling from the face can result in complete or partial removal of the eyebrows and eyelashes, while hair pulling from the scalp can result in varying degrees of patches of hair loss. The hair pulling and subsequent hair loss results in destress for the person, and can interfere with social and occupational functioning.
For some people, the symptoms of trichotillomania are manageable, but for others, the symptoms can be completely overwhelming.
