Qi deficiency and blood deficiency generally speak, it is blood deficiency that is more likely to cause hair loss, but the two can also coexist. Therefore, whether it is qi deficiency or blood deficiency, it is necessary to regulate promptly. If there is hair loss, one can usually eat some walnuts and black sesame seeds, which can help prevent the symptoms of hair loss. You can also eat more foods that supplement qi and blood, such as donkey-hide gelatin and jujube, which have the function of regulating qi and blood and improving symptoms. If the condition is severe, it is still necessary to take medicines that supplement qi and blood in time to be effectively treated. Most importantly, do not stay up late, as staying up late will aggravate the condition.
