What is the Chinese drink for hair growth?

I'm curious to know, could you elaborate on the notion of a Chinese drink specifically for hair growth? Is there a traditional herbal concoction or perhaps a tea that's believed to stimulate hair growth in Chinese culture? If so, what ingredients might be found in such a beverage, and how does it supposedly work to promote healthier hair follicles and growth? Additionally, are there any scientific studies or research that support the effectiveness of this drink for hair growth?
