All elves are dipped in Nair at birth and that prevents them from having any body or facial hair.
Elves can grow beards in their 'third cycle' of life. Of the elves we know, only Cirdan is certain to have entered this cycle. He has a beard in his appearance in Lord of the Rings. Mahtan was another elf who had a beard, though he was not in his third cycle.
The Hobbits we have seen in the films have not a trace of facial hair, not even a mustache. But rest assured, there are a very small amount of Hobbits that can sprout themselves a beard. Whichever Hobbits can grow facial hair owe this to a lineage tracing back to the Stoors.
Anatomy. Just like all other elves they look like humans with a slim, athletic or muscular build and V-shaped (Male) and Hourglass (Female) figure. They have leaf-shaped ears, and are hairless everywhere (except for hair on their head, eyebrows, and eyelashes) Males are very Androgynous.
Physical Qualities
Male half-elves can grow facial hair, unlike male elves, and often sport thin mustaches, goatees, or short beards. Half-elves'ears are about the size of human ears, but they are tapered, like the ears of their elven ancestors.
Physical puberty is generally complete by their fiftieth year (by age fifty they reach their adult height), but they are not considered full-grown until a hundred years have passed.
Trivia. Half-elves can have children of their own. When they form families with other half-elves, their offspring will be half-elves themselves. However, if a half-elf has children with someone of different ancestry, even a member of their parental races, the results can vary.
One of the probable reasons why feminine qualities of elves are played up is the intentional contrast between Elves and their traditional opposites, dwarves, who are basically hypermasculine: stout, muscular, hairy, axe-swinging drunks (which depending on the portrayal may apply to female dwarves as well, if they even ...
Tolkien's elves are immortal and only rarely have children, which means they wouldn't have regular periods.
Are grown-ups allowed to intervene? Santa advises that no family member touch their Elf on the Shelf, but he does describe a few rare instances when an adult may use tongs or potholders to help an elf in an urgent situation.
New research now suggests that while there was no interbreeding between these species and Homo sapiens, their existence could have overlapped with the arrival of Neanderthals and Denisovans, our closest ancient relatives, to the islands.
As for being stout, Tolkien says often that the Hobbits enjoyed eating and drinking. People who do hard physical work (like farming) can eat lots without becoming fat. The average Hobbit however appears to have been at least well-covered.
Well, the Hobbit shows that Elves can certainly get themselves drunk. They can also be killed by poison, so presumably an Elf could theoretically drink themselves to death. However, they would be unlikely to suffer much from the long term physiological effects of drinking.
Like fairies, elves were said to be diminutive shape-shifters. (Shakespeare's elves were tiny, winged creatures that lived in, and playfully flitted around, flowers.) English male elves were described as looking like little old men, though elf maidens were invariably young and beautiful.
Often elves do not possess facial or body hair, are not portrayed fat or old and are consequently perceived to be androgynous. As a race, Elves are more ancient than humans or other races, mentioned to have flourished in a sort of Golden Age which has been forgotten by other races.
Elves, at least the Eldar, have a pregnancy that lasts about a year. By the age of 1, Elves can speak, walk and dance. Puberty and full height are attained at around their fiftieth to one hundredth year, when they stop aging physically.
The bride's mother gives the groom a jewel to wear. Elves view the sexual act as special and intimate, for it leads to the birth of children. Elves cannot be forced to have sex; before that they will lose the will to endure and go to Mandos. Elves have few children, and there are long intervals between each child.
As with most creatures, the longer they live, the fewer children they tend to have. The elves do have relationships like humans and dwarves. However, as a rule, elves aren't as fertile as either of them, and as a result, they have many fewer children.
And it's exactly that: a choice. Unlike the other races of Middle-earth, casual intercourse was not enough to conceive a child because, for Elves, it was a far more conscious effort that required, as Tolkien put it, a "share and strength of their being, in mind and in body."
Monogamy is practised and adultery is unthinkable. By their very nature, they are "seldom swayed by the desires of the body" or influenced by lust. They marry only once for it was ruled by Manwë that, "'since the Elves are by nature permanent in life within Arda, so also is their unmarred marriage.
A female elf is a she-elf.
Age: Half-Elves mature at the same rate Humans do and reach Adulthood around the age of 20. They live much longer than Humans, however, often exceeding 180 years. Alignment: Half-Elves share the chaotic bent of their elven heritage.
Half-elves, as their name implies, are the offspring of humans and elves. Half-elves are a subrace unto themselves, blending the features of human and elf. Half-elves look like elves to humans and like humans to elves (hence their elven description as "half-human").
Per official Elf on the Shelf lore, a touched Scout Elf loses their magic. Learning this fact could leave your kids spiraling down an endless rabbit hole of unwanted outcomes — ending up on the naughty list and Christmas being cancelled being their chief concerns, according to my own kids.
