Situations with less possibility of self-healing: severe baldness (generalized baldness, total baldness), autoimmune diseases (such as lupus erythematosus) and other factors that are more difficult to be cured, with a longer course of the disease and a more serious condition, the general prognosis is poor, and it is difficult to be self-healed.
