Studysummary This study found that, among Indian men aged 50-55 with androgenetic alopecia, 78% of occipital donor areas fitted standard safe donor area criteria, but 22% did not, indicating a need for tailored selection in hair transplants. Our plain-language summary of this paper — not a Tressless recommendation.
In 2020, a study was conducted to profile and grade the pattern of receding hair in the occipital donor area among 681 Indian men aged 50-55 years with androgenetic alopecia. The researchers analyzed and photographed the occipital donor areas and graded the hair loss. According to their scale, 78% of the occipital donor areas were graded 1, 2, or 3 and met the standard safe donor area (SDA) criteria, while 22% did not fit well into the standard SDA grading scale. They also observed diffuse thinning and/or reverse thinning of the occipital donor area. The study concluded that there is no universally applicable SDA, thus selection should be conservative and overharvesting of the occipital donor region should be avoided.
