Chest hair growth is largely determined by genetics, hormones, particularly testosterone, and age. It typically stops growing when it reaches a genetically predetermined length, entering the telogen phase (resting phase) before eventually falling out and regrowing. Growth can also slow or cease due to aging, as hair follicles become less active. Health, nutrition, and stress levels can also impact hair growth cycles. If you notice a sudden change, it's worth consulting a healthcare provider to rule out any underlying issues.
