YOOO time to discuss noldrin hairstyle rules!!
In general: The longer the older/the more powerful. Hair shorter than the shoulders only as punishment for adult elves
upper left: Simple single braid, 3 strands, can be used by everyone, shows you're just a regular elf without any significant rank
lower left: two thick braids, 3 or 5 or 7 strands (depending on lover to fiance to spouse), from behind the ear, show that you are commited to someone
+ Bun, not braided, shows you reached mastery of your craft.
(Idea: Braided bun as guild leader of your craft?)
upper right: french braids on both sides joining into one on the back shows you are an apprentice to your craft.
Style of your hair in front of your ears, that is tied to the back shows the kind of craft. Simple loops for musicians, balloon braids for smiths, braid that joins into another behind the ear is for painters, and a thin strand that is woven into symbols for writers (though the symbol depends on what kind of writer)
lower right: Braided crown for high novles
Braids attached to the crown signify the rank:
13 Braids for the high king
9 for the crown prince(ss)
7 for the first born child of a king/queen/prince(ss) of the primary bloodline
5 for the other children of the primary bloodline/of the king/queen/prince(ss)
3 for the firstborn children of the secondary line and
1 for all other children of the secondary line
Which would mean before Finwes death he would have had 13, Feanor 11, Fingolfin 5, Maedhros 9 (or 7), Maglor 5, Curufin 5, Celebrimbor 3, Finarfin 5, Fingon 3, Turgon 1 etc.
