Your hair transplant will not heal unless you keep the newly operated-on skin out of the sunlight. The surgery will make the skin especially sensitive. If you protect the skin on your scalp after getting a scalp hair transplant, you will help the wounds heal much faster. You can start out by getting some kind of hat. The doctor must make the condition of the newly placed hair look like the patient's own natural scalp hair. The angle that the hair is put in determines how much it will stand up from the head. Once the surgeon has made all the hair transplant incisions that lay out the design he has created, the specially trained surgical team steps in. 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. 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. If you did not want your hair to look good, you would not have had the hair transplant in the first place. When you are having your consultation with the surgeon, explain the kind of hair style you would like to have. This gives him an idea of how best to create the design of the hair transplant receptor sites on your scalp. 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. The unit is set off by a band of collagen that holds it together.
