April 2012 in “BMB Reports” This study identified several DPC-specific proteins, including ITGB1, IGFBP3, and THBS1, as potential biomarkers for hair growth modulation through proteomic and network analysis.
January 2024 in “Journal of Medicinal Food” This study found that Nephelium lappaceum extract restored hair growth more effectively than finasteride in mice with testosterone-inhibited hair growth, suggesting its potential as a nutraceutical for hair growth.
In this study, Biofield Energy Healing significantly increased the proliferation of human hair follicle dermal papilla cells in vitro, suggesting potential as a hair growth promoter.
