Age needs to be considered when it comes to density. If the unit density is say 75% , medium to heavy and its worn by someone who is 50 years old then the look is very unnatural and a giveaway as fake

IMHO I strongly believe that there must be scalp showing to some degree as this looks natural.

I received a unit that's 60% density and there is plenty of scalp showing without looking like I am balding. The objective is to try and achieve a look that is natural and not "plastic"

The best units in the celebrity world are William shatner, Eddie Jordan, Enrique Inglesias as they look natural on them
