Head therapy has no obvious harm to the body. It can improve migraine, insomnia, dreaminess and forgetfulness, and can also relieve cerebral blood supply deficiency. However, when doing head treatment, you still have to go to a regular beauty salon and find an experienced beautician to operate, which will be more skilled and conducive to the early recovery of your body. Pay attention to keep your head warm at ordinary times. You'd better wear a hat when you go out in cold weather.
