Just for additional context on the Lamentations 4:7 line, the Nazarite vow involved taking a cow that was entirely red, without a single hair that wasn’t red, and sacrificing it.

And part of those vows involved being unable to cut one’s hair.

With a number of people having been identified as being Nazarites from birth.

So putting aside albinism/redheads might not be prudent in analyzing this particular passage.
