I think PaiGirish is on the look-out for a better hair-styling software than "DIGTIAL MAKEUP" and not general graphics editing/manipulation software.
I don't know how simple or extensive "DIGTIAL MAKEUP" was, but here are some suggestions--
1. Try "HairProLight". Download from htp://www.visualmusic.com/hp2008d.exe, it is 4.2MB download. It is freeware.
2. You may also try "Hair Master 4.0". It is a trialware of 44.32MB. Download from *download.cnet.com/Hair-Master/3000-2130_4-10572396.html
Price: Free to try (7-day trial); $24.95 to buy.
3. You may also like to look at the link below for a more wider lists of similar software (freeware / shareware / commercial) - *3d2f.com/tags/hairstyling/software/.
4. Lastly, what we all resort to - try Googling or Binging whichever your religion.
