For the first few weeks it is not wise to engage in any physically demanding activities. Then, the blood flow will be too much. Your transplants may start to bleed. It is important to clean your hair just as your doctor recommends after hair transplant surgery. You will be given a special shampoo to use and specific instructions on how and when to use it. You can move up or down from this figure according to your other factors such as thickness, curliness, or color. Then, you can use this number to figure up the grafts needed.

It is the needle going in with medication to numb the tooth that is the real agony.

Swelling is normal after hair transplant surgery and can even keep you away from work. 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. After their trials, they got the answer: the hair follicles themselves made the difference in the life of the hair and not where they were placed on the scalp. Once you start having the grafts done, you are committing to a full set of procedures. Otherwise, your hair will end up looking out of balance. 5. Do not get involved with a doctor who does not listen. A good doctor knows how important the hair transplant is to you. He will listen to your questions about hair transplant and provide intelligent answers. Do I think about my hair all the time? If you cannot think of anything but how your balding head looks, it is a good indication that you need to do something. This kind of thinking can distract you from enjoying the good things in life. It can also mean that you are not fully focused on the activity you are engaged in at the time.
