Graduation is simply referring to the density of the hair at the front area of a system....all systems, whether stock or custom-made, have a graduated density by default, unless specified otherwise [ in the case of a custom-made system].... it simply means the hair is less dense at the very front and ` gradually` [ Graduated] gets denser, further back towards the crown-point area, or as you ` progress` back from the front. The picture on the homepage [the ` before` and ` after ` shots] are of a non-graduated system....generally it`s only guys who are quite young can pull this look off..it looks totally unnatural on older guys, as very few, even with all their own hair , have a total ` wall` of hair at the front.
