Alopecia
Hairloss
Alopecia is the term used to describe the loss of hair or hair from where it should normally grow. It can affect any part of the body where hair grows, including the head, face, eyebrows, eyelashes and genital area.
Hair loss is a natural phenomenon as hair goes through a life cycle that includes a growth, resting and shedding phase. Alopecia occurs when this cycle is disrupted, or when the hair follicle is destroyed and replaced by scar tissue.
