Detailed answer

Hormones play a significant role in blackhead formation. Androgens, known as male hormones, can stimulate the sebaceous glands to produce more sebum or oil. Excess sebum production, along with the accumulation of dead skin cells and bacteria, can clog and block the hair follicles, resulting in the formation of blackheads. Hormonal changes during puberty, menstrual cycles, pregnancy, and menopause can often lead to increased blackhead formation due to the fluctuation in hormone levels. Additionally, certain medical conditions, such as polycystic ovary syndrome (PCOS), can cause hormonal imbalances and consequently contribute to blackhead development.
