Some people with ringworm of the head will lose their hair for a short period of time, and after causing hair loss, it is judged by the actual situation and type. If the damage is only very superficial to the hair shaft, in this case hair can grow back after the ringworm is treated, and this type of ringworm is usually leucoderma and nigricans, and hair can grow back. For ringworm pustularis, it invades more deeply and the entire hair follicle is destroyed, and because of scar formation, it is difficult for hair to grow back, and it is called permanent hair loss, so whether hair can grow back from ringworm depends on the type. It is important to treat ringworm early, as the later it is treated, the greater the chance of hair loss will be, and an early full course of treatment will relatively reduce the chance of hair loss.
