I'm making a sim of a friend who has a hairstyle like that but it's a nightmare trying to find any suitable hair. It's a nightmare to make. Any suggestions?

I've been looking for a short curly hair like that for awhile as well and the only hairs I've found that are even close to that are by alfred askew here and here

Links don't work, but I'm presuming you mean the Cropped Curly Hair for men and women?

If so, I've seen them, but being a picky sod, they just won't do, sorry!

I might try and mesh one myself.

sorry about that. the cropped curly hair for men was one of the ones I linked to, the other is the model b curls http://linna.modthesims.info/d/376366.
