Hair that falls out and has a white spot at the root usually grows back; this can be due to the formation of internal hair root sheaths or fat particles and is usually not something to worry about too much. There is no theoretical basis for the idea that a small white spot at the root of lost hair, which many people may think is a hair follicle falling out, will not grow back. In medicine, the white spot at the root of the fallen hair is known as the inner hair root sheath, which is a normal part of the hair follicle in the process of growth, and will not damage the hair follicle; in addition, some people have strong oil secretion of the scalp, which leads to the appearance of white fat particles at the root of the hair area; but no matter what the reason is, there will usually be hair growing out. If the patient’s hair falls out of the root with white spots, and at the same time there is local skin redness, pimples or flaking, etc., it may be folliculitis or ringworm of the head and other diseases, at this time you need to go to the regular hospital in a timely manner, standardized treatment under the guidance of a professional doctor.
