Many people boast that dead hair follicles can be revived, but they don't know that hair follicles will not increase in adulthood. If a hair follicle is reduced by one, it will be permanently missing. Hair follicle necrosis is equivalent to a person's inability to live, activate or even regenerate hair after death. If you have reached this level, then your hair follicle damage is quite serious, and it is very likely that some hair follicles have died and will never grow hair again. So it's best not to wait until it's too late to mend, but to pay more attention to maintaining hair follicles in peacetime. Hair follicle necrosis is not caused by rapid necrosis, but by long-term injury. Whether hair follicles and hair are healthy or not, they need maintenance, just like facial skin care. Maintenance is the best prevention. In the past, if there were a lot of necrotic hair follicles, we could only try our best to save them at this time. If these hair follicles are not maintained, they will be damaged and eventually die. It is impossible to activate necrotic hair follicles. I hope my answer can help you!
