Scar removal treatment; what are the possible scar removal options & how much can it cost? (Photos)

I had an accident a month ago and I had to undergo a forehead surgery due to excessive bleeding. It is a 10 cm long with 30 stiches. The after result a thin long scar which is very stressing for me. I want to know what are the possible scar removal options and how much can it cost. It's been 2 weeks I have been using dermatix which is a silicone gel but I'm afraid that even with time the scar might not completely fade.
