Question about whether HT can increase density

[barry77]

I'd like to have more density in the hair at the top of my head. There's what looks like plenty of hair there, it's just thin and looks nothing how it used to when I was younger. Can a transplant improve density? The photographs of fresh HT patients on this site show the implanted hairs arn't really all that close to one another, looks as though each hair has about a millimetre of clear around it which is kind of how I am now.

I've attached a photograph of the density I currently have (with a penny for scale). Can anyone tell me if a HT will help?

Any help very much appreciated!
