Genetics mainly cause hair loss, but diet, stress, smoking, and alcohol can worsen it. Treatments include finasteride, minoxidil, and lifestyle changes like a healthy diet and avoiding caffeine.
A permanent hair loss solution could involve reprogramming hair follicles to resist DHT using mRNA and siRNA. However, high costs, safety concerns, and the pharmaceutical industry's preference for ongoing treatments over one-time cures are major obstacles, with finasteride and minoxidil remaining standard treatments.
