Juan Felipe, it's more than obvious that the haircut in the linked image was pasted using Photoshop or any other image editing software, and it was a very clumsy edit, as I can see the seams between the pasted hair and the original image.
Instead of looking for it, I'd suggest you to grab Grammsims' Merida hair and look for an alpha edit that makes it look shorter, I think it should exist, Grecadea did a conversion to TS2 of that hair that can be found here:

From now on I'm just a lurker, the sad truth about the Orwellian status of the sims community is not "off-topic" neither is "politics".
