Visible curl is only part of the anatomy
Why Afro-textured hair requires specific experience
In tightly curled hair, the follicle beneath the skin may follow a curved rather than straight course. During individual follicular-unit extraction, the physician must anticipate that path to reduce accidental cutting or transection of the graft.
The external curl can also create useful visual coverage, but it does not justify a standard “fewer grafts” promise. Coverage depends on the treatment area, hairs per graft, calibre, curl pattern, scalp-to-hair contrast, styling, donor supply, and how the hair will sit when grown.
The diagnosis comes first. Pattern hair loss, traction alopecia, alopecia areata, central centrifugal cicatricial alopecia and other scarring disorders require different decisions. Surgery should not be used to bypass active inflammation or an uncertain diagnosis.
