If the grow room is not humid, and the flowers are not turning color due to rotting, I think you're okay. If you post a pic we can tell for sure. When the bud is 75% orange, it's harvest time
Hairs have almost nothing to do with harvest. They die when either useless, or already used ... you better hope they aren't already used, cause that's a big sign they're preggo. Otherwise, unlike PTS said, you harvest when it's somewhere over 50% amber TRICHOMES.
