Hairs are opaque by nature so the difference between clear and cloudy does not apply... the hairs aren't what we're concerned with here, but if you must harvest by hair color, wait until only tiny and occasional tufts of fresh white hairs are being produced.

It's the crystals you are interested in... didn't you ever get a bag and look at it and go, ooooh! it's so CRYSTALLY!!!?
Go get a magnifying glass and look closely at the buds. Or google the term 'trichome'. Better yet, search 'trichome ripeness chart'.
