harvest.

do all hair turn red or will some still be white.

Depends on the strain.
When the red hairs recede then it is
ready for harvest.

Yea it depends on strain, but sometimes there are a few white left. Usually mostly amber though. Some strains all amber so it's hard to say.

Trichomes really a better way to tell when to harvest, I find hairs to be too variable. Jewelers loupes are a couple dollars on eBay.
