    GlossaryHair Medulla

    innermost layer of a hair strand, often containing air spaces

    The hair medulla is the innermost layer of a hair strand, often composed of soft, spongy cells that may contain air spaces. While its exact function is not fully understood, it is thought to contribute to the hair's overall strength and may play a role in the hair's ability to insulate. Not all hair types have a medulla, and its presence can vary between individuals and even among different hairs on the same person.
