do human hair or facial hair tend to grow during the night when the body is not active or during the day?

Mostly at night as your body is at rest and

better able to repair or renew itself.

Edited to reword for the simple minded.

Pepper.

It grows constantly throughout the day. Hence Five O'clock shadow.

It grows constantly at the same rate, regardless of time of day or season of the year... hair doesn't "know" what morning or night means.

it grows 24/7, ever heard of a 5 o'clock shadow?

I wanna know that too...
