,
September 2016 in “Indian Journal of Plastic Surgery” This article describes a modified follicular unit extraction technique using a reverse rake scalp elevator, which may reduce follicular transection rates in hair transplantation from the lower occipital donor region.
May 2020 in “Hair transplant forum international” 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.
January 2014 in “Journal of Cutaneous and Aesthetic Surgery” The document suggests that for better patient satisfaction in hair transplants, high-quality photos are needed, and using a narrow donor strip might lead to fewer grafts and dissatisfaction, but filling the scar with FUE grafts and using tranexamic acid can improve results.

August 2016 in “Journal of Cosmetic Dermatology” This study found that intradermal injection of normal saline before follicular unit extraction significantly reduced wound size and skin mass removed compared to acute extraction, suggesting it minimizes skin injury in this procedure.
10 citations
,
July 2017 in “Archives of Plastic Surgery” This study found that hair diameter varies significantly within the occipital safe donor area, with thicker hair in the upper sections and thinner hair in the lower sections.
8 citations
,
June 2001 in “International Journal of Cosmetic Surgery and Aesthetic Dermatology” This article reviews methods for managing the donor area in hair restoration surgery to minimize scarring and reports no new results.
2 citations
,
May 2018 in “PubMed” In this study, hair restoration using follicular unit extraction removed about 35% of donor area hair density, indicating a need for careful consideration of varying donor densities.
September 2026 in “Journal of Cosmetic Dermatology” This study developed a geometric framework for estimating safe donor harvesting in hair transplants, showing that individual hair characteristics like caliber and length significantly affect donor capacity.
March 2026 in “Frontiers in Medicine” This study reported that two male patients with diffuse unpatterned alopecia exhibited donor-area involvement in both the vertex and occiput, challenging the assumption of occipital stability for hair transplantation, and showed partial improvement following treatment with oral finasteride and topical minoxidil.
March 2026 in “Dermatologic Surgery” This study found that platelet-rich plasma significantly accelerated wound healing in the donor area after follicular unit excision for hair transplantation in men.

February 2002 in “Dermatologic Surgery” Best hair transplant results happen when tissues are least damaged.
13 citations
,
January 2013 in “International Journal of Trichology” This study found that androgenetic alopecia patients showed significantly higher perifollicular lymphocytic inflammation and fibrosis compared to controls, emphasizing the need for histopathological evaluation during hair transplantation.
2 citations
,
September 2020 in “Dermatologic Surgery” Hair transplant surgery can cause temporary hair loss in the area where hair was taken from.
December 2023 in “Facial Plastic Surgery” This chapter reviews the technical and artistic considerations for maintaining high-quality cosmetic outcomes in patients undergoing follicular unit excision for hair transplantation and provides no new clinical results.
April 2020 in “Journal of Cosmetic and Laser Therapy” In this study, researchers identified optimal hair follicle and follicular unit densities for successful hair transplantation in male patients with androgenetic alopecia in China.
2 citations
,
January 2015 in “Hair therapy & transplantation” This study reports that both prolene and staplers are effective for closing the donor area in hair transplants, but staplers offer convenience and time efficiency.
October 2021 in “Indian Journal of Plastic Surgery” This article reviews the use of trichoscopy for differentiating mimickers of patterned hair loss and assessing donor sites in hair transplant patients, without providing new clinical findings.
April 2023 in “Journal of Cutaneous and Aesthetic Surgery” In this study, researchers analyzed the occipital donor area for hair transplantation among men aged 50–55 with androgenetic alopecia and found that while most subjects met standard safe donor area criteria, individual variations suggest a conservative approach to donor area selection.
10 citations
,
January 2013 in “Journal of Cutaneous and Aesthetic Surgery” This article discusses the unsightly scars left in the donor area after follicular unit transplantation and highlights the need for studies on cosmetic improvements, but it reports no new research findings.
January 2023 in “Skin appendage disorders” The case study reports a patient with acute telogen effluvium in the donor region post-hair transplant, highlighting trichoscopic findings that aid in diagnosis and reassuring the self-resolutive nature of this condition.
1 citations
,
January 2017 in “International Journal of Dermoscopy” This study found that trichoscopic digital imaging is a safe and accurate method for assessing the donor area in patients undergoing hair transplantation, helping to plan graft utilization based on hair density and follicular unit measurements.
November 2024 in “IP Indian Journal of Clinical and Experimental Dermatology” This study found that the severity of acute donor site effluvium after hair transplants was significantly correlated with the number of grafts extracted and longer surgery durations.
June 2024 in “Indian Journal of Plastic Surgery/Indian journal of plastic surgery” This study found that using a specific ratio method based on the patient's scalp measurements can effectively predict the dimensions of the permanent safe zone for hair transplants, particularly in early stages of androgenetic alopecia, potentially ensuring long-lasting transplant results.
