    GlossaryShadow Cells

    Shadow cells are a type of keratinocyte found in the hair follicle, specifically in the outer root sheath. They are characterized by their large size and reduced cytoplasmic content, which gives them a "shadowy" appearance under a microscope. These cells play a role in the hair growth cycle and are thought to be involved in the regeneration of hair follicles. Their presence and behavior can be relevant in understanding hair loss conditions, as changes in shadow cell populations may indicate disruptions in normal hair follicle function.
