Baizhu hair, also known as Radix Polygoni Multiflori Preparata, is the root of the plant Polygonum multiflorum. It is a traditional Chinese medicine that has been used for centuries to treat a variety of conditions, including hair loss, premature graying, and other hair problems.
Baizhu hair is a good source of antioxidants and other nutrients that are essential for healthy hair growth. It is also believed to have anti-inflammatory and antibacterial properties that can help to soothe and protect the scalp. As a result, baizhu hair is often used in hair care products, such as shampoos, conditioners, and hair tonics.
