180% density wigs are used to achieve the most voluminous and natural look. This density is best for a full and thick look. It is perfect for those with larger head sizes, as it requires a lot of hair to make the wig look natural.
The density of a material is usually expressed as a specific number, usually in grams per cubic centimeter, that represents how tightly packed the material is. In the case of a 180% density, this means that the material is 80% denser than the original material. For example, if the original material had a density of 1 gram per cubic centimeter, then 180% density would mean that the material now has a density of 1.8 grams per cubic centimeter.
