Have a look at this site.... http://www.hairfinder.com/menshair.htm ....just pick a suitable one and enclose the pic with your order rather than worrying about the technicalities....that`s my advice anyway.... once you have settled on the style you`d like, it`s then a matter of getting your density correct in relation to your side/back hair [if you are going for a topper]---you might like to have a look/experiment on this site which Antywanty posted some time ago.... you can see what different styles would look like on you: http://www.taaz.com/ Paul.
