What do Chinese use on their hair?

I'm curious to know, what are the common hair care practices and products that the Chinese people tend to use on their hair? Are there any traditional or culturally significant hair care rituals that they follow? And if so, what are they? Additionally, are there any specific hair styling trends or techniques that are popular among the Chinese community? I'm eager to gain a deeper understanding of the hair care habits and preferences of this diverse and vibrant culture.
