Henry Margu Color Chart Hope by Henry Margu: Hope's beautifully tailored layers with slight bends and long, side-swept bangs create an elegant salon look. A monofilament crown adds more natural volume at the top of the head. Monofilament (Mono) is an extremely sheer mesh used to make a transparent base that creates a realistic looking scalp area and is then hand knotted with individual fibers to simulate the appearance of natural hair growth. A Monofilament Crown (Mono Crown) cap contains a Mono area in the top area of a machine-made cap. This allows for the fiber in this area to have a more natural and realistic appearance and is often used on shorter wig styles in the crown or in the center area of a style that is flatter and with less volume in the top.
