Detailed answer

Constant use of safety helmets or hard hats can contribute to the development of hyperpigmentation. The pressure and friction from the helmet or hard hat can cause inflammation and irritation on the skin, leading to an overproduction of melanin, which causes increased pigmentation. Additionally, the sweat and moisture trapped underneath the helmet can create a breeding ground for bacteria, which can further worsen skin issues. It is important to ensure proper hygiene practices and give your skin breaks from wearing helmets or hard hats to minimize the risk of hyperpigmentation.
