It is amazing that this first started with a doctor who wanted to transplant hair to give people new eyebrows. Dr. Okuda of Japan was busy trying to transplant hair to the eyelashes and eyebrows of people who had lost them traumatically. This was before World War II. When the war broke out, his discovery of hair transplant procedures was squelched until two decades later. Gho has done some work and acquired a Dutch patent on his work with hair multiplication. It is unclear whether this is much like hair cloning or not. That is because Dr. Gho neglects to submit his findings to be published in medical journals. Without review by other doctors, Gho's theories cannot be tried and evaluated. Many doctors will refuse to do immediate hair transplants if they are put to the test. There are advantages to getting hair transplant surgery under the age of 25. Most of these patients are healthy. They do not usually take medications. They are often optimistic and have the motivation required to make the commitment needed for what may end up being lifelong treatment. The first part, and the one most people getting hair transplant surgery are interested in, is the hairs. There should be one to four full hair follicles in the unit and one or two fine hairs as well. There are sebaceous glands in the follicular unit which produce oil. The follicular unit is a living unit with muscle, nerves and blood vessels that are all tiny enough to fit into this small package. If the patient does not have straight hair, her curly hair must be inserted by rotating it so that it lies even with the curve of the brow that is being made. One drawback to eyebrow hair transplant surgery is that eyebrow hair, which usually does not grow, will grow and need to be cut because it is actually scalp hair. To get 25% of that, you would need 156 follicular units per square inch. All that remains is to measure your balding area and multiply the number of square inches by 156. When you know what number of grafts to expect during your hair transplant surgery, you will be a savvy consumer. It does not hurt one bit go into the process with an idea of your own about how the treatment should go.
