Classic Curl is a tighter, well-defined ringlet, springy and uniform from root to tip, with volume that builds through wear. It sits around a Type 3B: a proper curl for clients with naturally curly hair who want a seamless blend. Set on our Tape In, each piece is a flat, fast tape that sandwiches onto the natural hair in minutes, with no heat, rings or sewing. The curl is set into the hair, so it holds its own volume and springs back after every wash with no heat needed. Supplied 16 to 28 inches in Russian Remy, across all 70 Blush+Wren shades. Lengths are measured straight, with 1 to 3 inches of natural shrinkage once the curl settles.
