Hair density in wigs, quite simply, is about how full or thick a wig appears.
But not all wigs are created equal, especially when varying vendors throw their spin on density numbers. One might wonder, “Why does a 150 density wig from Vendor A feel fuller than a 180 from Vendor B?”
What is density in lace wigs
Lace wigs density is basically telling you how thick a wig or unit is.It measures the numbers of hair per square inch. How full the wig is.
Personally, I’ve never been able to tell human hair lace wigs density just from looking at it and feeling it.
You can look up wig density charts that show photos of what the hair looks like on the lace for different densities,you can reference. but it’s worth noting that, if the human hair lace wig is really full at the top near the lace, as it goes down, it thins out and isn’t as full, and the ends are really thinned out.
Then, how can we judge the human hair lace wigs density?

What is density in lace front wig?
In the world of lace front wigs, density is represented by numbers, such as 130, 150, 180, and beyond. Higher numbers equate to more hair on the wig, giving a fuller appearance.
Wig density is not just a marketing buzzword; it involves precise calculations and balances.Typically, it involves the weight of hair, measured in grams, crossing between bundles and closures or frontals to reach the desired density.
Take our lace front wigs for example,our lace wigs made by 100% human hair, less short hair.
A 150 density 18 inches wig might include two full bundle and a portion of another, along with a lace frontal, totaling roughly 260 grams. As you add more bundles, the density and therefore the fullness increase.
130% density is made with one and half bundle and closure or lace frontal.
180% density is made with two and half bundle with lace closure or lace frontal.
Some prefer lighter wigs, using fewer bundles for an everyday look, while others opt for that dramatic impact. Mix and match bundles with closures or frontals, play with density and find your crown of glory.
