May 2026 in “Journal of Cutaneous and Aesthetic Surgery” In this study, researchers developed a novel bio-enhanced hair transplant technique that, among 10 patients, provided aesthetically pleasing outcomes with minimal downtime, linear increases in density over nine months, and uneventful donor area healing with no visible scarring.
September 2025 in “Journal of Cutaneous and Aesthetic Surgery” This case report demonstrated that long-hair follicular unit extraction may effectively reconstruct the mustache area following surgical scarring, with high patient satisfaction and no complications observed.
June 2024 in “Journal of Dermatology & Cosmetology” This comparison study identified non-shaven FUT long hair (FUL) restoration as potentially offering more aesthetic benefits and fewer scars than FUE or conventional FUT for treating various types of alopecia.
January 2024 in “Journal of cosmetic dermatology” This study found that long-hair follicular unit excision for hairline restoration resulted in high patient satisfaction, with a 93% graft survival rate and improved quality of life scores postoperatively.

September 2022 in “Frontiers in veterinary science” In this study, researchers used high-throughput sequencing to explore lncRNA interactions in cashmere goat hair follicles during embryonic development, finding lncRNAs potentially regulate genes in the Wnt and PI3K-Akt pathways related to hair follicle growth.
This study identified specific lncRNAs and mRNAs differentially expressed in miniaturized follicles compared to normal follicles in patients with androgenetic alopecia, with AL136131.3 potentially inhibiting hair growth and accelerating follicle transition to catagen through effects on glycolysis-related genes.
January 2021 in “Figshare” This study reported that exposure to melatonin promoted hair follicle fiber growth in an in vitro Cashmere goat model, potentially by influencing pathways related to the extracellular matrix and microvascular system.
January 2018 in “Figshare” In this study, melatonin exposure promoted hair follicle fiber growth in Cashmere goats, suggesting that it may mediate hair follicle development through long non-coding RNAs affecting vascular and extracellular pathways.
January 2018 in “Figshare” This study found that melatonin exposure promoted growth in Cashmere goat hair follicles in vitro and suggested that lncRNAs play a key role in regulating this process, particularly through pathways involving the microvascular system and extracellular matrix.
