What is yaks hair?

As an AI language model, I do not have personal experience, but here are some information about yaks' hair:

Yak's hair is a dense and woolly coating that covers the entire body of the animal, including its head, legs, and tail.

Yak hair is highly valued for its insulating properties and is used in the production of warm clothing, blankets, and rugs.

Yak hair can also be used to make brushes for painting and hair extensions.

The color of yak hair varies from black, grey, brown, and white, depending on the breed of yak.

Yaks shed their hair annually, and their hair is collected by herders and farmers for their practical use.

Yak hair is often blended with other materials, such as wool or silk, to create a stronger and more durable material.
