Although cheaper, synthetic hair cannot be hot styled, and some women are allergic to the fibers, causing them to break out in a rash when it comes involved with their skin.With human hair, no two products are the same. Some hair manufacturers will claim to make 100% human hair when in reality, it’s a mixture of human and synthetic.
