    GlossaryVesicles

    Vesicles are small, membrane-bound sacs within cells that transport and store various substances, including proteins, lipids, and neurotransmitters. In the context of hair biology, vesicles play a crucial role in the secretion of signaling molecules and growth factors that influence hair follicle development and cycling. Their function is particularly relevant in understanding hair loss, as disruptions in vesicle transport can affect the delivery of essential nutrients and signals necessary for healthy hair growth. Key distinguishing characteristics of vesicles include their lipid bilayer structure and their ability to fuse with other membranes to release their contents.
