Shaving an adult’s head will stimulate hair follicles to grow hair and make it coarse and hard, but it usually takes several repeated shaves to achieve certain results.
Hair growth is directly related to the function of the hair follicle, and when the blood vessels as well as the nerves around the hair follicle are abundant, the hair growth rate will perform better. Repeated shaving will cause some irritation to the hair follicles, enlarging the localized follicles, which will result in the newborn hairs becoming coarse and hard.
When the hair follicles are damaged and the normal blood supply is affected, hair loss and delayed hair growth may occur. For people with obvious symptoms of hair loss, it is necessary to consult a doctor in a timely manner, and under the guidance of the doctor to improve the relevant examinations, as soon as possible to clarify the cause of the disease, and then targeted treatment.
