Insufficient cerebral blood supply and hair loss can be treated with oral Cipro, Ginkgo biloba drops and vitamin E to soften blood vessels and improve blood circulation; oral oracetam and piracetam to improve cerebral metabolism; and also oral blood-raising and brain-clearing granules. Hair loss caused by insufficient blood supply to the brain is mostly due to chronic cerebral blood supply deficiency. In chronic cerebral insufficiency, it can cause ischemic-hypoxic encephalopathy, and patients can experience hair loss, inattentiveness, lax thinking, memory loss, and in severe cerebral insufficiency, it may cause cerebral infarction. Insufficient cerebral blood supply can occur in young people as well as in middle-aged and elderly people. Insufficient blood supply to the brain in young people may be caused by vascular malformations, such as arterial stenosis, or it may be caused by prolonged mental tension, stress, or sleep disorders. It may also be caused if the patient looks down at the cell phone or plays with the computer for a long time. In addition, it can also be seen in people who have been smoking for a long time. In the case of middle-aged and elderly people, most of the cases are caused by atherosclerosis. Patients usually have a history of high blood lipids and diabetes, and the main clinical objective is to improve blood circulation, soften blood vessels, and control blood lipids and blood sugar.
