The doctor will blend it in with the grafts as he goes. It may seem odd, but once the grafted hairs are set, they are just as strong as the rest of your hair. You can cut them, comb and brush them, and even dye them in time. New hairs start to grow within three months. You will find you need haircuts more often, as your hair will grow about one or two centimeters per month. Scar revision surgery is usually done at a flat fee, perhaps around $1000 for the procedure. The normal hair transplant procedure will cost differently depending on the number of grafts even though the cost per graft goes down the more grafts you have. For example, 100 grafts may cost you $1500, while 3000 grafts may cost about $12,000. Excessive plucking can be a problem, too. Burns, tattoos, and infections can cause the eyebrow hair to fall out, and some people just are not able to grow eyebrows at all. Hair transplant surgery for eyebrows is different because eyebrows are different from scalp hair. For one thing, the hair has a distinct growth pattern with each section of the eyebrow pointing in a different direction. A follicular unit is a single entity that is made up of several parts. All these parts are necessary to the whole. 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. A scientist named Dr. 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. When you shop for a hair transplant surgeon, you will find that different doctors give widely varying estimates of the number of grafts you will need. This can make you very uncertain about the wisdom of even getting a hair transplant. It helps to have a fair idea of what to expect. Unfortunately, there are hair transplant surgeons who do not take their position of respect seriously.
