No one actually uses chopsticks in their hair, and if you see something you think are chopsticks, they're hair accessories made specifically for being hair accessories, not eating utensils. Most of these "chopstick" hair accessories are decorated and much shorter than chopsticks used for eating. Some Koreans use these hair accessories now but not many. It was much more common 50 years ago.
Japanese chopsticks are typically made from a variety of woods, with the most common being bamboo, cedar, and cherry. Bamboo is favored for its lightweight and durability, while cedar and cherry are appreciated for their aesthetic qualities and pleasant aroma. Some high-end chopsticks are crafted from rare woods like hinoki (Japanese cypress) for their natural resistance to moisture and bacteria. The choice of wood can also influence the chopsticks' texture and grip.
