Mithril or otherwise, are we concluding that it was routine practice for Elves to fix up their hair a few times a day? For whatever reason the idea seems to tickle me. I'm just envisioning Saeros touching up the cowlicks with a bronze mirror in the lavatory...
ETA: as an unofficial "poll of opinions", I googled Saeros fan art. The vast majority portrays him with long hair, a couple pictures have him with shoulder length-ish hair. In every case his hair is at least as long as Turin's, and usually longer. Oh the irony.
