Which Hairstyles are available to which life stages?

This is a list of hairstyles in The Sims 2. Some of the hairstyles that have hats are not currently listed, but this list is being expanded over time. Note that the hairstyles that come with the Mansion and Garden Stuff stuff pack are not currently listed, as I have yet to find out the names of all the hairstyles, and what hairstyles they are linked to for life stages that cannot wear the said hairstyles.

Hairstyle names that are in bold are the hairstyles that are intended to be selected for the Sim. So each or most hairstyle name should only be listed in bold once. Please note that in addition to most of the hairstyles from The Sims 2 and its expansion packs, I have also included several Maxis match custom content hairstyles that I felt were worthy of inclusion.
