Scar On Right Eyebrow?

It is possible that you would be a good candidate for a scar revision.  You would need to be evaluated for this problem to determine the best method of revision.  

Regarding the cost aspect of your question, it depends on the definition of "cost" or who's paying for it. If it's considered reconstructive and covered by insurance, then the insurance company (with a lot of government mandates) controls the costs and reimbursement to those who provide the service. If the government is paying for it (Medicare, Medicaid, ObamaCare), then the government gets to decide the costs and reimbursement. If you treat it as an elective and your-choice procedure (not necessarily cosmetic), then you get to decide who's going to do it, what is to be done, where it's to be done, and how much you're willing to pay for it. The least expensive would be a scar revision/excision done in a plastic surgeon's office under local anesthesia where you are told before the procedure exactly what the costs will be and agree to this. You can also shop around to compare costs. If it's done in the hospital setting or under general anesthesia, it will cost considerably more. The same thing would happen for a mole on your skin that you want removed even if it doesn't need to be removed for medical reasons. Another example would be repairing a split earlobe from an earring tear.
