Azizi-
my first thought was one of my favorites for Christmas, a Carol by Alfred Burt:

                  Some Children See Him


Some children see Him lily white
the infant Jesus born this night
Some children see Him lily white
with tresses soft and fair

Some children see Him bronzed and brown
the Lord of heav'n to earth come down
Some children see Him bronzed and brown
with dark and heavy hair (with dark and heavy hair!)

Some children see Him almond-eyed
This Saviour whom we kneel beside
Some children see Him almond-eyed
With skin of yellow hue!

Some children see Him dark as they
Sweet Mary's Son to whom we pray
Some children see Him dark as they
And, ah! they love Him so!

The children in each different place
Will see the Baby Jesus' face
Like theirs but bright with heav'nly grace
And filled with holy light!

O lay aside each earthly thing
and with thy heart as offering
Come worship now the infant King
'tis love that's born tonight!

'tis love that's born tonight!

And--
I can only remember a fragment now of a song a cousin used to sing about a girl with "hair like a horse's tail." I believe it was referring to a pony tail of dark, thick hair.
