    GlossaryHalf-Life

    Half-life refers to the time required for the concentration of a substance, such as a drug or hormone, to reduce to half its initial value. In the context of hair loss and hair biology, understanding the half-life of hormones like dihydrotestosterone (DHT) is crucial, as prolonged exposure to elevated levels can contribute to conditions like androgenetic alopecia. Key distinguishing characteristics of half-life include its dependence on metabolic processes and the implications it has for treatment efficacy and timing in hair loss therapies.
