The reason why a woman’s hair falls out badly is related to the type of hair loss, which may be androgenetic alopecia, patchy baldness, resting alopecia, anagenetic alopecia, telogen effluvium, scarring alopecia, and so on. 1. Androgenetic alopecia: this is related to heredity, mainly because of the high level of androgen in the body, androgen is broken down into dihydrotestosterone, which will make the hair follicles tiny, and the hair in anagen phase will gradually become thinner and finer, and ultimately make the hair follicles shrink and disappear, and the hairs will fall off. 2. Patchy baldness: Patchy baldness refers to patchy hair loss, which is related to autoimmune, hereditary, emotional stress, endocrine and other factors. 3. Resting hair loss: this condition is common after surgery, postpartum, severe mental stimulation, so that the hair follicles enter the resting phase in advance, causing massive hair loss. 4. Anagen phase alopecia: Anagen phase alopecia is common in patients after chemotherapy, due to the side effects of the drugs, the hair in the anagen phase suddenly stops growing and falls out in large quantities. 5. Tension alopecia: If you tie your hair tightly for a long time, it will lead to hair pulling and hair loss. 6. Scarring alopecia: due to trauma and other reasons, scalp scars appear, hair follicles are destroyed, so that the hair no longer grows. People hair loss is very serious to pay attention to, it is recommended to go to the hospital for a detailed examination, for the cause of the symptomatic treatment.
