Thanks for asking that question. Doing a transplant on the sides is very difficult. The reason is that the donor area is typcially the back of the head. The hair in that area is thicker diameter hair. The hair in the temple area is usually finer hair and then gets thicker as it goes toward the back of the head. So to get a realistic temple area you need fine diameter hair. And that’s the difficult part. And in general transplants have been a dicey option. Often the hair does not ‘take’ to the new area or it ‘takes’ and then falls out over time. Your best option is to go with the flaps and expand your template as necessary. Good luck.
