After a couple of weeks, you can replace the cap with sunscreen. It should have an SPF of at least 30. Having just the right amount of blood flow to the hair transplant sites will make a big difference in how fast they heal. For example, you need to make sure you get enough blood flow during the night. That is because a naturally-occurring enzyme in the body combines with testosterone to create a chemical called DHT. This chemical is responsible for the hair loss on the tops of men's heads when they have male pattern baldness. However, it does not affect the back and sides of their hair in most cases. You would have to go through many surgeries and your head may never look the same. This is why you should never accept any doctor's offer to do a few hair grafts and see how you like it before doing a full hair transplant surgery. Once you start, you are committed. 3. You need several days of rest afterward hair transplant surgery. If you do not have the cash, your doctor can usually point you to several different financing methods. That way, you do not have to come up with the money all at once. Discuss healing with your hair transplant surgeon. Because you may be having plugs removed, you have more healing to do than someone who is having a routine hair transplant. 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. He will also try to find out what your goals are to see if they are realistic. 6. Keep it realistic. If the doctor says the hair transplant will cost an exorbitant amount of time or money, be wary. Underestimating Procedures. Certain surgeons and clinics underestimate the number of procedures necessary to achieve the desired effect. This leads people to have a false hope of having a full head of hair in a very short time. When this does not happen, they are understandably angry. They did not get what they were promised.
