January 1989 in “Journal of Investigative Dermatology” This study found that sebaceous glands in bald scalp have greater androgen binding affinity and capacity than those in hairy scalp, possibly contributing to the androgenic response seen in male pattern baldness.
May 2026 in “International Journal of Molecular Sciences” This study found that plucked hair follicles can serve as a practical and scalable source for regenerative medicine, as researchers successfully isolated and expanded keratinocytes and mesenchymal stem cells for potential cell-based and cell-free therapies, demonstrating significant wound-healing bioactivity in vitro.
