Kevin was largely bald, and his scalp had been changed by disease, lesions, and scarring. In this chapter of The Bumpinator, Dr. Sanusi Umar explains how he planned customized scalp pigmentation to create the semblance of hair while working with the complex terrain left by dissecting cellulitis and Kevin’s scalp condition.
Creating the Semblance of a Shaved Head
Dr. Umar decided to use what he calls trigopigmentation to give Kevin the semblance of hair, with the goal of making him look like someone who had shaved his head. The challenge was not simply adding pigment. The design needed to blend with a scalp that had developed undulations, color variations, and scarring.
As Dr. Umar explains, the aim was to create something that would “camouflage it, and make it still look natural.”

Planning the Pigment and the Blend
According to Dr. Umar, considerable planning went into the choice of pigment and how it would be applied. The lesions had left scarring, while variations in the scalp’s contour and color meant the pigmentation had to be designed around what was already there rather than treated as a uniform surface.
That planning focused on blending the pigmentation into Kevin’s existing scalp appearance so the final design could visually absorb some of the irregularities instead of drawing more attention to them.
Framing the Hairline and Temples
Hairline placement was another part of the design. Dr. Umar says Kevin’s hairline was brought down and framed with a temple design intended to cover much of the abnormal-looking area on his scalp. This was especially relevant because the condition had already extended toward his forehead.

A Customized Design for Kevin’s Scalp
The chapter shows why Dr. Umar approached Kevin’s pigmentation as a customized design problem. Pigment selection, blending, hairline position, and temple framing all had to account for the scalp’s existing contour, color variation, and scarring. The focus in this chapter is the planning behind that approach, without moving ahead to later results.
