Hair loss, for those who go through it, is a pressing psychological stress. It can be caused by a variety of reasons from genetics to anxiety and there are various methods of treating it with varying success. But all the methods are for hair loss in its early stages, for those past the initial stages and want to have hair back, hair transplant (in Korea and everywhere else) is actually the only proven solution.
Hair transplant involves collecting hair follicles from other parts of the head and transplanting them to areas of the head where hair loss has progressed. Usually, hair is collected from the back of the head as this is where hair loss is least likely to occur. Hair transplant is the only fundamental solution to gaining hair back with few health-related side effects (compared to other medicinal treatments) but it does come with a financial burden for the surgery itself. But hair transplant surgery is a common procedure in Korea with lower costs than many other countries.
