Hairline Raising? is This Possible.

Easy way to raise your hair line would be laser hair removal or just plucking out the hairs you don't like.This may be the most ideal solution but it would not involve surgery and it would not involve scarring.Laser hair removal will not leave you with a natural hair line since there is no fine control of removing hairs one by one.  

It would be helpful, if you would provide more photos. That would make the answers you get more objective.

What you describe is in essence the opposite of a hairline advancement procedure, or a browlift.  The hairline can be raised by as much as 2 to 2.5 cms most likely, through a few small incisions within the hairline. It is important to consult a surgeon with particular experience in these procedures.

Most plastic surgeons can do a brow lift that can raise your hairline at the numbers you are discussing. 

This can readily be done if the brows are sagging and the forehead is very elastic. It will involve the loss of some hair at the hairline or an endoscopic brow lift can be done. If the forehead is tight, expansion surgery can be done.

Hairline raising is possible and it can be a difficult problem. Raising the hairline can be done surgically or endoscopically but may also lift the eyebrows a bit. My recommendation is to see someone who does endoscopic browlift work for a consultation and see what they reccommend.
