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 overtime. Note that the hairstyles that come with University, Family Fun Stuff, Glamour Life Stuff, Pets, Seasons, Bon Voyage, Teen Style Stuff, Free Time, and Mansion and Garden Stuff 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. Enjoy! :)

Notes:

 * I commonly refer to the hidden "Bad" hairstyle introduced with the Open for Business expansion pack for adult males as the "Mishap" hairstyle, because the only way to get the hairstyle without using cheats is by receiving a negative makeover by using the hair salon.
 * I commonly refer to the "Bangs" hairstyle introduced with the Open for Business expansion pack for adult males as the "Locks" hairstyle, or even as the "Bowl" hairstyle. In the case of the former, it's because I try to refrain from using American words where possible, if I have the option to use a word that is more commonly used in New Zealand, or less commonly used in America. In the case of the latter, it's because it is shaped like a hairstyle that is commonly referred to as a "Bowl Cut" in real life.
 * I commonly refer to the "Long Bangs" hairstyle introduced with the Open for Business expansion pack for adult males as the "Long Locks" hairstyle, because I try to refrain from using American words where possible, if I have the option to use a word that is more commonly used in New Zealand, or less commonly used in America.
 * I commonly refer to the "Short" hairstyle from the base game for adult males as the "Short Simple" hairstyle, because it is a short and basic hairstyle.
 * I commonly refer to the "Short Simple" hairstyle from the base game for adult males as a "Gibs" hairstyle, because of it's similarities with the hidden "Gibs" hairstyle, for adult males which is also introduced in the base game, though unlike the "Short Simple" hairstyle, the "Gibs" hairstyle can be worn by child male Sims. In that regard, I tend to address the "Gibs" hairstyle as the "Gibs [Hidden]" hairstyle to distinguish between the two.
 * I commonly refer to the "Sixty" hairstyle from the base game for adult males as the "Helmet" hairstyle or the "Helmet [Sixty]" hairstyle, because it is shaped like a helmet.
 * I commonly refer to the hidden "Bad" hairstyle introduced with the Open for Business expansion pack for adult females as the "Mishap" hairstyle, because the only way to get the hairstyle without using cheats is by receiving a negative makeover by using the hair salon.
 * When using the randomise button to randomise a child female Sim's appearance through BodyShop, if the "Barrette" hairstyle appears, there is a chance that it may be linked to the "Halo" hairstyle for teenagers and up. Most of the time it will be linked to the "Barrette" hairstyle for teenagers and up, but it's possible for it to be linked to the "Halo" hairstyle instead.
