Our hair extensions specialists provide the best hair extension applications possible. Hot Fusion Hair Extensions Salon Miami uses top quality 100% Real Hair. The main difference between natural versus synthetic hair extensions is how they are made. Natural human hair extensions are made from human hair that's typically given by a donor. 100% human hair extensions are just that—they're made of 100% human hair. Likewise, hair extensions might have & virgin hair, which is 100% human hair that has never been chemically treated or dyed. Remy hair, considered the finest quality of human hair, is human ponytail hair that keeps the hair cuticle intact and aligned in the direction it grew, giving the extension a natural look and feel.
