Thanks CIT and HMorHT for your comments. @CIT, of course you will find poor scalp pigmentation, sadly, no different to poor hair transplants, we have treated poor hair transplant results with scalp pigmentation. Being able to mimic the size of a hair follicle is an art, it requires an artistic skill and high quality pigments. @HMorHT, the contrast of the pigmentation needs to be controlled against the natural characteristics of the hair when it is shaved, sometimes a darker tone can work fine, but each case has to be taken on it´s merits. Here are some larger images.
