Human hair is the best type of hair to use in a weave. Human hair, for obvious reasons, looks the most realistic when added to a head of existing natural hair for the purpose of body or length. Even though human hair is more expensive to obtain, it is recommended because it can be curled, blow dried, cut, colored, and even highlighted.
Human hair is the most expensive type to purchase because it has been grown by people with the sole purpose of cutting their hair and selling it for use in weaves and wigs. Most human hair is grown by individuals who live in Asian countries, but a good portion of human hair also comes from individuals living in India. The least expensive type of hair that is still considered natural, but not human, is Yak hair. This type of hair is more textured and course, but can still be successfully used in hair weaves.
