Alopecia areata is defined as the loss of more than 100 hairs per day, and losing about 100 hairs per day is not considered severe hair loss. Hair is an appendage structure of the skin, and usually the number of hair loss is about 50 to 70 per day, while the same number of hair regrowth also occurs. When the number of hair loss is significantly greater than the number of hair regrowth, it is also called alopecia areata in clinical practice. Comparatively speaking, hair loss of about 100 hairs per day does not belong to serious hair loss. Hair loss in the clinic is mainly seen in androgenetic alopecia, baldness, and female postpartum hair loss, etc. After timely clarification of the cause of the disease and through standardized treatment, the symptoms of hair loss can generally be controlled. If you experience hair loss of about 100 strands per day, it is recommended that you consult a doctor in a timely manner for standardized treatment under the guidance of a doctor.
