Base
Hair Systems are made on mesh or polymer (PU) basis, or combination of both, have different durability, different density.
French lace hair systems where hair is knotted to the mesh are the best for achieving a very natural look with a lot of density.
Swiss lace bases are by far the most natural looking and feel, but also one of the most delicate materials. It cannot hold much density, since the lace is much thinner.
Mono lace has two layers of material. Silky fabric under the lace makes the softer finish for a scalp.
The other popular base for the hair systems is a polymer base close to skin look, with injected hair into silicone.
Other variations include lace base with poly on the sides and back or extra poly on the crown. These hair systems provide you that natural look of a full lace and a very similar feel in texture of course. The only real difference is that it provides that extra durability with the poly edges. Also, it makes cleaning much easier in the poly areas without damaging the hair system.
Standard size of the base is 8 x 10”, smaller sizes are also available.
