scalp mobility hair transplant surgery donor strip area anatomical structures

Studysummary This study conducted in a hair restoration clinic found that using the vertical scalp mobility method resulted in a significantly greater number of hairs available from the donor strip compared to the horizontal method, with an increase of approximately 970 hairs (P < .05).

The study compared the effectiveness of horizontal and vertical methods in assessing scalp mobility for hair transplant surgery in 15 patients. It found that the vertical method provided a significantly larger donor strip area (49.1 cm² vs. 42.0 cm²) and more hairs (6762.5 vs. 5792.8) than the horizontal method, with a 12.8% increase in width and 969.7 additional hairs available for harvesting. These results were supported by another study, and the importance of measurement level was emphasized due to the influence of anatomical structures. The data is not publicly available but can be requested from the author.
