If however, the surgeon estimates a similar number, just make sure all the grafts go onto the balding parts of your scalp. To calculate the number of grafts you need for hair transplant surgery, there are several factors to take into account. The thickness of the hair shaft makes a difference. Whether the hair is curly or straight determines if the hair will lie flat or stand up, creating more fullness. It will be just as full as it ever was. 2. Bleeding. The hair transplant surgery will likely cause some bleeding. If you put pressure on the area, the bleeding will usually stop. In rare situations, the bleeding does not stop this way. In that case, it might be necessary for the surgeon to do some extra stitching to close the wounds. If a patient is known to suffer from keloid scarring, the first thing a reputable doctor will do before hair transplant surgery is to explain the possibility of unsightly scars. This requires a very honest surgeon, since the patient may decide the procedure is not worth the scarring it will cause. The next step with such a patient would be to discuss ways the keloid could be covered. Any good doctor knows the decision is yours to make. 2. Try not to use a doctor who starts you off with a salesman or other person who has nothing to do with the health occupations. You need a person with good training to show you all you need to make your mind up about the surgery. You do not need a person whose only agenda is to sell you on getting hair transplant procedures done. In fact they often watch television or read magazines, being awake and alert the whole time. Hair transplant surgery is surely less painful than it was in earlier times when larger sections of scalp were excised. This involved more cutting to take out the donor hair and more cutting to insert the donor hair into the recipient site. 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.
