Hair loss due to kidney deficiency, which has been occurring for half a year, generally only requires timely improvement of kidney deficiency. Additionally, in daily diet, consuming more walnuts, black sesame seeds, and black soybeans can effectively help alleviate the condition, and some patients may experience hair regrowth. Moreover, it is important to avoid consuming overly spicy and stimulating foods, as excessive intake can increase the burden on the stomach and intestines, leading to functional disorders in the body, which can exacerbate the condition. It is recommended to pay more attention to rest and avoid frequently staying up late.
