A rough framework for how graft requirements scale with pattern stage and area covered. The framework is general; the specific number for your case depends on hair characteristics, donor density, and goals — that comes from a photo consultation.
Graft requirements scale with pattern progression and area covered. The ranges below are typical for each stage — your specific number could be higher or lower depending on hair coarseness (coarser hair covers more visual area per graft), donor density (some patients can support larger sessions), and the density target you actually want at the front.
Hair coarseness. Coarse hair covers more visual area than fine hair at the same density. If your donor hair is naturally thick, the same graft count delivers more apparent density.
Hair color contrast. Hair that closely matches scalp color creates the appearance of higher density per graft. Dark hair on light scalp requires more grafts for equivalent visual density.
Donor density. Patients with dense donor areas can support larger sessions. Patients with naturally thinner donors are limited in single-session capacity.
Density target. A “visible-density” result requires fewer grafts than a “maximum-density” result. Discussing your actual goal in consultation refines the count significantly.
Hairline irregularity. Natural-looking hairlines use more grafts at the front edge for the soft, irregular appearance — and fewer behind. The shape of the design affects the total count.
The framework above gets you to a rough range. The specific number for your case comes from a photo consultation — Dr. Jones reviews personally and sends back a written estimate within 48 hours.
