Direction of hair growth after procedure

[joneric]

Hi guys. Newbie to the forum. Great site. Looking for some advice.

I had an FUE transplant a couple of years back following a not very successful strip procedure some years previous. The FUE transplant has given some but not full coverage. I had the procedure to cover a wide bald surgery scar on the side of my scalp only, not for male pattern hair loss. The problem is that the hair does not grow in the correct direction to cover the scar area making the coverage look even less. Hair gel helps a little. My question is what can I do to train the hair to grow in the correct direction? Any hair treatments available?

Thanks for any advice you can give.
