November 2020 in “Research Square (Research Square)” In a mouse model, this study found that intradermal keratin injection stimulated hair growth and suggested its potential use for treating hair loss by promoting hair regeneration.
November 2025 in “Cosmetics” This study evaluated a hair mask containing rice germ oil GX-N and ferulic acid on damaged hair and found that rice germ oil GX-N improved hair characteristics after bleaching, UV, and heat exposure, but adding ferulic acid did not provide extra benefits.
November 2016 in “Oncology Letters” This study suggests that the expression patterns of keratin and filaggrin indicate milia may originate from the outermost cells of the hair bulge in the outer root sheath.
April 2024 in “bioRxiv (Cold Spring Harbor Laboratory)” In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.
