Hair treatments depend on technology in the form of transplants and hair extensions. During a hair transplant surgery, the doctor takes hair from the sides, or back of the head and places it on the bald area. The surgeon performs a transplant surgery in the clinic after giving a local anesthesia to the patient. According to research, baldness often occurs due to genetics. But, some other factors also cause baldness like illness stress, unhealthy diet, and some drugs.
