Scarlet Hair Extensions only use hair, known in the industry as “remy.” Remy is hair which cuticles are aligned and running in the same direction. This is important because when some of the hair shafts get turned in the opposite direction tangling becomes a major issue. And while some suppliers promise to provide remy hair, they include hair that has possibly fallen to the floor during the manufacturing process and then added back to the bundle, often times with the cuticles turned in the wrong direction. What sets Scarlet apart is they take the extra step to test the hair from their suppliers to ensure it’s remy.
