A scalp skin based wig (also called a skin base wig or PU base wig) is a type of wig where the cap is made using a thin polyurethane (PU) layer that looks like real human skin. This gives the illusion that hair is growing directly from the scalp, making it one of the most natural-looking wig bases available.
Unlike lace wigs, which use a mesh lace material, skin base wigs use a smooth, skin-like surface that closely mimics the appearance of a real scalp.
How it works
The base is made from a thin PU (polyurethane) material
Hair is either:
Injected into the base (so knots are not visible), or
Hand-ventilated into tiny holes in the skin layer
The scalp area looks flat, realistic, and slightly shiny like real skin
The wig is secured using combs, clips, adhesive, or glueless straps
