The hair forms a sharp angle so that it grows out and then flat to the face. Scalp hair has a much gentler angle. Eyebrow hairs do not grow in the same type of follicular units as scalp hair. Rather than growing in groups of one to four hairs, they are simply single strands of hair. You can see this if you look carefully in the mirror at your eyebrows. This leaves many potential candidates for the surgery in the dark. It is difficult to know the difference between a good hair transplant surgeon and an inexperienced one. If you know someone who has had hair transplant surgery, you have at least one person to whom you can go for advice. You will know from looking at their hair whether the job was done well. You should not have to put up with this for long. 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. If at all possible, you need to be able to visit with patients the doctor has treated so they can show you the results in person. You are not asking too much - it is a major commitment you are making. 4. If your doctor says to try a few hair transplant grafts and then decide, run. This is never a good idea. Treatment can often last one to two years. 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. One reason they do not happen more is that antibiotics are given before and after the procedure to prevent infections from even starting. 9. Cysts. Cysts can come up in the areas where the hair is being transplanted to, also called the recipient areas. The cysts do not usually last more than a few weeks and are rarely more than the size of small pimples.
