This study found that segmental single hair analysis produced ocfentanil concentration profiles similar to those from hair lock analysis, supporting its use in cases with limited samples.

This article notes that hair restoration surgery generally has a complication rate of less than 1%, but highlights rare instances of serious cardiovascular events.

Hair restoration greatly improved George's confidence and self-identity.

This article reviews the classification and complexity of keratin protein groups in hair follicles, but reports no new experimental results on their transcriptional events.

This study explored the molecular factors behind delayed wound healing in obesity, highlighting that systemic changes like inflammation and collagen deposition alterations contribute to sustained skin inflammation and reduced mechanical resistance.

This study observed that autologous platelet-rich plasma treatment improved hair count and density in areas with androgenetic alopecia compared to placebo, with differing outcomes based on the PRP collection device used.

This review discusses neural mechanisms involved in hair growth control, focusing on piloneural interactions, but reports no clinical findings; the authors suggest further exploration for managing hair growth disorders.

This study found that Merkel cell clusters require Frizzled6 signaling for their polarity information, while other hair follicle-associated structures align their orientation based on the hair follicle itself.
