Yes, 100% human hair is real hair. It's any hair that has come from a human scalp, whether it's from a hair salon floor, a brush, or even a corpse.
While "100% human hair" is a broad term, it encompasses a wide range of hair qualities. Remy hair, for example, is a type of human hair that has the cuticle aligned in one direction, resulting in smoother, less tangled hair. Virgin hair, on the other hand, is 100% human hair that hasn't been chemically treated or dyed.
When shopping for hair extensions, wigs, or other hair products, it's important to consider the different types of human hair available and choose the one that best suits your needs and budget.
