So, you wonder why hair are not growing back in Androgenetic Alopecia? It is because the dermal papilla cells are turning into zombies cells. A topical senolytic compound is absolutely needed for results.
Cellular senescence: Cellular senescence is one phenomenon by which normal cells cease to divide. In their seminal experiments from the early 1960's, Leonard Hayflick and Paul Moorhead found out that normal human fetal fibroblasts in culture reach a maximum of approximately 50 cell population doublings before becoming senescent.[1][2][3] This phenomenon is known as "replicative senescence", or the Hayflick limit. Hayflick's discovery that normal cells are mortal overturned a 60-year-old dogma in cell biology that maintained that all cultured cells are immortal. Hayflick found that the only immortal cultured cells are cancer cells.[4]
