People with severe hair loss or baldness can choose to have hair transplants based on their individual circumstances; they can either choose to have a hair transplant or not. Having a hair transplant can achieve aesthetic effects. After the transplant, new hair will grow, giving someone a revitalized overall appearance. Hair transplants involve taking hair follicles from the back of the head as the source, separating them into single units, obtaining multiple follicular units, and transferring them to the area that needs the transplant, enabling them to survive and grow, thus addressing the effect of hair thinning in certain areas.
