Excessive drinking may be a problem due to anesthesia and medications you have to take in the course of having your hair transplant done, so you may be asked to refrain from drinking until your head has healed. You may even be told whether or not to take certain vitamins and medications. The doctor will discuss where your hair transplant procedure will take place. Another aspect of choosing donor sites is the color of the hair being used in the hair transplant. If it does not match the area around the balding area, it will look unnatural. The texture should be even as well as the waviness or curliness of the donor hair and the area of hair around the balding area. Also, she will give an honest accounting of what she expects the procedure to cost. An unscrupulous surgeon, on the other hand, will distort the facts about his hair transplant procedures. He will try to get the patient started by stating that the price will be very low. He will know all along that the procedures will cost much more, but he will lowball the price anyway just to get the patient started so that they have to finish. Based on the fact that the average Caucasian male has a density of 2 hairs per millimeter, it can be assumed that the average density of hair is 1250 hairs per square inch. Figuring at an average of 2 hairs per follicular unit, it would take 625 follicular units per square inch. To get 25% of that, you would need 156 follicular units per square inch. If you have a high number of hair follicles per square centimeter than most people, more grafts can be done, so your hair will look fuller. 3. Your scalp laxity will also affect the fullness of your resulting hair transplant site. This refers to the flexibility of your scalp. How loose your scalp is helps to decide how many grafts can be done just as hair density does. Mega-sessions where thousands of grafts are done in one sitting help to shorten the overall time. However, the length of these sessions is often grueling. 5. Hair transplant surgery may be combined with other procedures. If you do not have enough hair, you cannot have a normal hair transplant surgery.
