There are several reasons why we say that the hair is dizzy or sunken, such as cervical spine problems or blood pressure problems, or insufficient blood supply to the brain due to vascular sclerosis, which can cause this dizziness. Of course, one very important reason cannot be ignored is anemia, red blood cells are oxygen-carrying cells. If it is anemic, it will actually have a lack of oxygen to various organs. This time is actually the same as cervical spondylosis, hypertension, and insufficient blood supply to the brain symptoms, there will be hair dizziness or dullness. It is advisable to go to the hospital to screen the causes, different age groups may have different reasons for dizziness, for example, the elderly may be more often seen in the cerebral blood supply deficiency, while long-term ambulatory work may have cervical spine problems. In young women or teenagers, it may be related to stress, exertion, or even body position, and then there are patients with asymptomatic hypertension, who also need to monitor their blood pressure at different times under the guidance of a doctor to detect hidden blood pressure abnormalities. So, just dizziness is not enough to determine the cause directly, but must be screened for all these aspects to be clear.
