For hair loss due to kidney deficiency, treatment should first address the kidney deficiency to achieve effective improvement. For example, one can start by consuming foods like Chinese chives, goji berries, and Chinese yam, which can help alleviate symptoms of kidney deficiency. Additionally, regularly consuming walnuts, black sesame, and black beans can also help improve hair health and achieve the treatment goal. In severe cases, it is still necessary to take medication in a timely manner to get effective treatment. It is important to avoid getting cold and staying up late.
