Most of the mothers have black and shiny hair before delivery, but after delivery, the hair looks particularly thin and lusterless, in fact, this is a very common clinical situation, according to statistics, about 35% to 40% of women in the clinical postpartum hair loss phenomenon of varying degrees. The so-called postpartum alopecia, also known as “childbirth alopecia”, refers to a large number of women’s hair loss within a period of time after childbirth, there are often such patients in the clinic, and distressed by it, so what kind of postpartum alopecia in the end, how to prevent and deal with it? 1.Characteristics of postpartum hair loss Postpartum hair loss mostly occurs 2-6 months after delivery, hair first from black to yellow, then from the forehead hair one-third of the hair began to fall off, making the hairline back, then the temples and the top of the head hair also gradually fall off, serious waves can be the whole scalp, so that the hair becomes thin and yellow. 2, the causes of postpartum hair loss In summary, the common causes of postpartum hair loss are the following, (1) changes in hormone levels. In general, hair is divided into three growth cycles, namely the growth phase (about 3 years), the regression phase (about 3 weeks) and the resting phase (about 3 months). Hair in the anagen phase is actively proliferating, hair in the regressive phase stops actively proliferating, and hair follicles in the resting phase shrink, causing the hair to eventually fall out. Under normal circumstances, hair growth and loss are in a dynamic balance, and it is normal to lose no more than 100 hairs per day, but once this balance is broken, there will be an abnormal increase in hair loss. After pregnancy, due to the increase of estrogen in women’s bodies, the rate of hair loss slows down, the dormant period of hair is relatively longer, and some hair is “overdue”, and after delivery, the estrogen level in their bodies gradually returns to normal, those “overdue” hair will be quickly After childbirth, the estrogen level in the body gradually returns to normal, those “overdue” hair will fall off quickly, and new hair can not grow out in time, forming this phenomenon of “green and yellow” in a short period of time, thus forming a large number of hair loss after childbirth. (2) Mental factors. Some women suffer from “postpartum depression” after childbirth due to physiological or psychological reasons, manifesting as depression, frustration, even anxiety, fear, irritability, which is aggravated at night; coupled with the newborn baby often crying, maternal night rest is not good and other factors, will make hair loss increase, while the increase in hair loss and aggravate Maternal negative emotions, in turn aggravate hair loss, thus forming a vicious circle. (3) Qi and blood deficiency, hair loss of nourishment. Chinese medicine believes that “the hair is the remainder of the blood” and “the kidney is the master of the hair”, after childbirth, maternal Qi and blood deficiency, kidney yin deficiency, resulting in hair loss of nourishment, thus causing a lot of hair loss. 3, the prevention and control of postpartum hair loss (1) keep a relaxed mood, the mother should correctly understand that postpartum hair loss is only a normal physiological phenomenon, in general, after 6 months to 9 months of childbirth, the hair will grow out on its own, no need to be overly anxious and worried, bad mood will only aggravate hair loss. If you suffer from “postpartum depression”, consider seeing a psychiatrist, and try to ensure sufficient sleep. (2) Ensure nutritional intake, the mother should not be afraid to take in nutritious food because of the premature pursuit of postpartum body recovery, to achieve a balanced diet, appropriate supplements. Ensure the intake of green vegetables and fruits, moderate intake of protein-rich foods such as fish, poultry, pork, beans, eggs, etc. (3) Hair care, many women in the “moon” period do not wash their hair, afraid of the so-called “wind”, but this practice invariably aggravates hair loss. Because the entire “moon” period if not wash hair, the scalp will accumulate a lot of sebaceous secretions, blocking hair follicles, affecting the blood supply, thus increasing the chances of hair loss. Therefore, it is necessary to pay attention to hair cleaning during the “menstruation” period, in addition to frequent massage of the scalp or combing with a wooden comb to improve the blood circulation of the scalp, which has the effect of preventing hair loss and promoting hair growth. (4) If the hair loss is serious, you can take some medicines under the guidance of a doctor, such as multivitamins, trace elements and some dietary therapy, if necessary, you can take the Chinese medicine to nourish Yin and blood.
