The Mono Long by Jon Renau is a monofilament hairpiece constructed of synthetic fiber. The base of the hairpiece measures 6.5×5.75 and the overall hair length is 917. The monofilament fiber is sheer allowing it to blend in with all skin tones and the construction allows for easy styling and multi-directional parting. This hair addition is great for adding extra volume to thinning crown hair. Have a professional trim in a bang, layers, or customize the piece to blend with your natural hair.
