"Louisiana Man" Doug Kershaw never tightens his bow hairs. He leaves them limp, and somehow loops his thumb under the frog and uses that to adjust the tension. If his hairs went limp, he'd just move his thumb to tighten them up again. BTW this is also how he does quadruple-stops with ease. Just a suggestion! I don't seem to have this problem with my fiddle, and I live in the most humid place on Earth!
