What's the difference between these two types of foreheads/brows?

[BertrandRussell]

Mine resembles the more 'curved' one and I would really like the one which looks more straight.

How would you describe the difference? Are there any surgeries which address this?

 

[Jason Voorhees]

Rounded high forehead and straight Sloped foreheads.The latter looks better. You could get forehead implants or Fillers in this area to get that look
