At Mooi we pride ourselves on how our hair extensions can be easily dyed and naturally blended/styled with your own hair. Our weft hair is thinner than your traditional sew-in weft hair, which allows the hair to lay flatter on the head andcreates virtually invisible look. Our Brown Extensions is 100% Cuticle Remy Hair. With the proper maintenance you can expect the life span to be 6-12 months.
