Shaving your hair does not necessarily mean that you will grow better hair. If the hair itself is of good quality and damaged due to frequent perming and coloring damage to the hair, the hair that grows back after shaving the hair will be better than the current damaged hair; if the hair itself is fine and soft and of average quality, then the hair that grows back will not change much compared to the current hair. The thickness of the hair is determined by the hair follicle. After shaving the hair, the cross section of the hair becomes larger, and visually there may be a phenomenon that the newborn hair becomes better, in fact, when the hair grows again, it will be found to be the same as before. Shaved hair does not necessarily grow better hair, if you want better hair, you need to go to the dermatologist, under the guidance of the doctor to find the cause of the symptomatic treatment.
