This question, asked by a member of our Hair Restoration Social Community and Discussion Forums, was answered by Coalition surgeon Dr. Cam Simmons:
I see a lot of hair transplant doctors doing perfectly straight hairlines while others take the uneven or jagged approach. What are the arguments for or against this? Is it just a preference or does it depend on the degree or pattern of hair loss?
Natural hairlines have what recommended hair restoration physician Dr. Bill Parsley refers to as “Macro-irregularities” and “Micro-irregularities”. There are peaks and valleys in the basic shape and finer irregularities in the leading edge of the hairline.
Coalition member Dr. Ron Shapiro’s concept of a “transition zone” before the defined zone of the hair transplant is also very important. A strongly defined saw-tooth pattern looks as unnatural or more unnatural than a strongly defined straight hairline.
When recreating a natural-looking transplanted hairline on a balding scalp, it is a good idea to build-in some peaks, mounds, or notches in the defined zone and soften that further with irregularly placed 1-haired grafts in the leading edge and 2-haired grafts in the transition zone.
