Can a Craniotomy Scar Be Avoided?

My son is worried that after he will have craniotomy, (and it is to remove the lesion) and having a big scar, it will be very noticable and hair will not grow at the scar. Can it be avaided? What can he do before? Any recommendation? Also, can you make hair grow on scar tissue? What is the success rate?

Talk with his surgeon and let him know of your concern. Worst case scenario and there is a linear area that won’t grow hair after all is said and done, I have fixed many craniotomy scars with hair transplantation.
