When you choose the basic design of the men's hair replacement system, you often see two names-polyurethane and thin skin. You may be confused by them and want to know their differences and advantages. Toupeec answers this question for you.





PU is an abbreviation for "polyurethane". After the liquid polyurethane is used for lace or monofilament material coating, it is dried in a special equipment to form a polyurethane substrate. PU is covered on lace or monofilament. Below is a base with PU side and back. We can see monofilament material through PU.


Thin skin


Thin skin is a piece of material made of polyurethane (broadly speaking, thin skin is a type of polyurethane). It is not coated, but connected to lace or monofilament material. Below is a base with thin skin on the sides and back. We can see that the thin skin is connected to the monofilament, with only a narrow connecting band. We cannot see monofilament through thin skin. Thin skin can be used for the entire base.



In order to distinguish whether it is PU or thin skin, you can see whether it is covered on lace or monofilament, or connected to lace or monofilament. There is not much difference between PU and thin leather in use; they are both used to enhance the durability of the base, making it easier to apply tape or glue, and making cleaning easier.Hair can be knotted by single knots, single splits knots, reverse split knots, double knots, etc. using either of these bases.
