Usually, there are much confusion about which ventilation method should be chosed. We will introduce the most widely used two ventilation methods in articles. They are Single Reverse Split Knot, Double Reverse Split Knot.

 

Single Reverse Split Knot

 

This ventilation method could be applied on most of the lace and mono base, such as French lace, fine welded mono etc.

 

The adventage of this knotting method is that single reverse split knots can create out very small knot. But, due to the knot is small, hair is easy to loose and shed. Is there any thing we can do to avoid the knot loose? The answer is YES. Sometimes, we can brush a very thin of liquid "glue" on the lace, as soon as the "glue" get dry, the hair will be secured well on the lace, mesh holes still remain there and breathable.

 

Single reverse split can also be applied on thin skin hair systems. Skin is not slippy as lace, single split knot can hold strong enough on skin base. Moreover, we will push a layer of glue on the bottom after knoting. So the knot can hold very strong.

 

In a brief, single split knots is a good solution for those people who want a natural scalp appearance.

 

Double Reverse Split Knot

 

This ventilation method could be applied on most of the lace and mono materials, such as French lace, fine welded mono etc.

 

The adventage of this knotting method is that the knots is with strong holding, the hair is not easy to shed, however, double reverse split knot
is bigger. It is easier to be detected.  So, if you need the system more durable and pay little attention to the appearance, then doulbe reverse split knot would be your better choice.

 

But, more times, we recommed that if the base materail is lace, you can use single reverse split knot in hair line area and double reverse split knot in other areas. Then the system will has both
nice appearance and more long life span.
