    GlossaryHair Aging

    natural changes in hair color, texture, and density over time

    Hair aging, also known as aging hair or hair ageing, refers to the natural process where hair undergoes changes in color, texture, density, and strength over time. This can include graying due to reduced melanin production, thinning as hair follicles shrink, and increased dryness and brittleness as the scalp produces less oil. These changes are influenced by genetic factors, hormonal shifts, and environmental exposures.
