the density of full lace wig, how to choose it

some friends ask , how to choose get a wig with the right density?
full lace wig ask natural look. which include density look.
this is very important.
firstly let us see what the factory can offer:

Extra Light = 50% thickness of an average head of hair.
Light Density = 80% thickness of an average head of hair.
Light to Medium = 100% thickness of an average head of hair.
Medium = 115% thickness of an average head of hair.
Medium Heavy = 130% thickness of an average head of hair.
Very Heavy = 160% thickness of an average head of hair

of course, it also have 140% and 150%
when you choose it, you choose a density same to your hair . some client think much hair is
good, but if your hair density only be 100% , but you choose a wig with 150% density , it will not natural.

some client donot like to use number , they like describe the density and hair amount.
"i want much hair ,cannot see the lace." but this will be easy to cause ambiguity.
most of factory only do them at 130% , because 140% have been hair cover all lace.
but it still need hair amount is much . so, the right density should be 160% or 180% .

but if it is first time for you to purchase from a factory,i suggest you buy a set of density chart.
and the density chart must be made of swiss lace. not smooth mono. because density on different lace is different.
