Some clients prefer to look as if they have early signs of MPB. They opt for a general thinning look all over rather than full density on their crown and top of their head. In order for this type of effect to work it is necessary to create a thinning hairline to subtly match the top of the head. This type of thinning and MPB result can be achieved by changing the density of SMP replications per square inch and varying the colour of pigments throughout the scalp.
