The Elves Hair

I've just noticed something unusual; Tolkien never mentions how long the elves hair really is. The movie makes them out to have long, pretty, but straight hair and that's how I've assumed them to be. However I saw some early drawings of artists inspired from Tolkien - and all the Elves have short, curly hair - rather like the Irish fairies are reputed to look like. Tolkien makes his Elves to have bright hair with a shining star or whatever, but did anyone actually notice if he actually described their length or texture?
