    GlossaryOverexpression

    production of a gene's product in unusually high amounts

    Overexpression refers to the process where a gene is produced in higher-than-normal amounts within a cell. This can happen naturally or be induced artificially in a lab setting. In the context of hair and alopecia, overexpression of certain genes might lead to excessive hair growth or, conversely, contribute to hair loss if the overexpressed gene disrupts normal hair follicle function.
