Male-pattern baldness is a hereditary condition that happens with ageing, also known as androgenic alopecia. Over time, the hairline recedes to form the shape: “M”. Hair fall can also be triggered in men when experiencing stress or illness. As we’re exposed to more environmental stressors due to our changing climate and exposure to pollution, it’s become more common for men to experience sudden, heavy shedding, also known as telogen effluvium.
