Like sheep hair is used for making wool why human hair is not used?

Human hair is not used to make fabric because:

• Human hair is thicker than animal hair making it more wiry and prickly.

• If human hair is used to make fabric, we need to add soft animal fibre like alpaca wool or goat hair to make it work making it more expensive.

• Moreover, there will also be an issue of the supply of human hair in the market.

Hence, even though it is possible to spin human hair into yarn and other types of thread but we won't get a very desirable result.
