Traditional Chinese medicine believes that hair is blood, which can be understood as hair that grows out of people and is transformed from excess blood. So if you want to control hair loss or speed up hair growth, you need to nourish the liver and kidney. Ligustrum lucidum has the effect of nourishing liver and kidney, so it is beneficial to hair growth, but the causes of hair loss are complicated, so it is not enough to use this. The specific situation is still better to go to a regular big hospital for examination.
In the late stage of hair loss, if the hair follicle is closed, you can consider hair transplantation.
