Yaki hair is a type of hair that looks and feels similar to African American hair. It goes through a special type of processing in order to look like straight hair. The process is also known as "relaxing the hair."
Yaki hair comes from the animal called the yak. This is a male cloven-hoofed cattle, related to the bison.
Yaki hair when processed is typically straight, smooth and shiny. There are different types of yaki hair available, with regular straight yaki hair being the most common. Other types include kinky straight that is fluffy and thicker, making it more natural, and curly yaki hair.
