This is an interesting question, because one would think that looking in the mirror would be more a problem of people who have already had hair transplant surgery. Actually, quite the opposite is true. When people are concerned about balding, they spend much time looking into a mirror to double-check and re-comb their hair to make it look like it covers more of their heads. If your expectations are too high, you may be referred to counseling before a reputable doctor will perform a hair transplant. If you are positive yet realistic, you may be ready for the next step. Next, the doctor will get all the facts on your health that are related with surgical procedures. Uncontrolled high blood pressure would be a problem. 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. When a young man gets a hair transplant procedure, it can avert many problems with low self esteem and lack of self confidence. Others have thyroid disease or other diseases that affect their hair. A certain type of alopecia results in eyebrow loss. 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. Rather than just moving around individual hair follicles, surgeons actually moved a unit which contained everything the hair needed to keep growing. The results were ground-breaking. One way surgeons used to move the donor follicular units to the balding areas was by single strip harvesting. This is done by moving small strips of tissue containing follicular units. They used hair from the fringe, or back and sides of the head, to accomplish this. The doctors were trying to determine whether hair follicles were balding resistant because of where they were located on the head or because of something inherent in the follicles themselves. This would settle the issue of whether hair transplant would work by those methods.
