They are then multiplied and combined. The end result is an increase in the number of hairs available for hair transplant. Not only is hair cloning possible, it has been proven in many scientific studies. Recently one group of researchers did a culture whereby they multiplied the number of dermal papilla cells. This will give an idea of whether there is hope for a good result that will last for a fair amount of time. You will also need to reveal to the doctor if you have had any hair replacement surgery before. To get an idea of how you will react to having a hair transplant procedure done, the doctor will ask many questions. Anyone who has had a tooth pulled knows that, if the tooth is deadened properly, it is not the tooth-pulling that hurts. It is the needle going in with medication to numb the tooth that is the real agony. Of course, to follow the dental analogy, after the numbing wears off there is plenty of pain where the tooth was before. Actually, there is a hair transplant procedure that keeps the scarring to one thin line. It consists of cutting the new thin donor strip immediately above the original scar. In most cases, the old scar is removed at the same time. When the wound is stitched up, the entire area of both the old scar and the new cut are sewn into one line. In most cases, they do not have large areas of stable balding-resistant hair follicles. The sides and back of their hair tends to thin just as the front and top of the head do. The DHT affects all the areas of their hair. Any hair follicles that are affected by DHT will simply fall out if they are moved by hair transplant procedures. Yet, if you use your imagination, you can see how the right style would make the hair transplant look great. Before you go in for your hair transplant surgery, your surgeon will give you some facts about how to care for your hair before the surgery and after. He will emphasize that the hair on your crown should be at least 2cm long.
