Since the young patient will be dealing with this problem for a long time, this is a necessary consideration. When the hair transplant surgeon achieves a higher hairline, he will be able to get more fullness on the top of the head because he has less to cover. This is not to say the young person will have a receding hairline when the procedure is complete; just that the hairline will not be too low. 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. How Are Follicular Units Used in Hair Transplant Surgery? Certain doctors have been aware of follicular units for a long time now, but the knowledge only recently made its way into hair transplant methods. Now these ideas are being used in hair restoration every day. To understand how follicular units have affected hair transplant surgery practices, it is necessary to first understand what a follicular unit is. A common quote for hair transplants is between $2 and $10 per graft. The reason for the wide variance is mainly because the price per graft decreases the more grafts you have done. Often, the price per hair transplant session is quoted. This may be a lunchtime session. For example, 200 grafts may be done in a short session for $2000. Just be sure that you do not bother the hair transplant site by scratching or rubbing it. Your hair transplant doctor will want you to come in for a check of your transplants about a week after your surgery. Be sure to be at that appointment on time. If you have any questions about how to care for your hair, bring them up at that time. It would do this by multiplying the hair a patient already has rather than using up the good hair that still exists on the patient's head. Hair cloning is done by taking stem cells, or dermal papilla cell, and cloning them in a laboratory setting. They are then multiplied and combined. The end result is an increase in the number of hairs available for hair transplant.
