Yes, I also take 2 showers/day because of working out at night. I don't know your hair type, but I'm guessing it's fine because of your saying it gets stringy (mine is fine--very very fine). I started using a conditioner by Aussie called Knot Forgotten and it really helped me. I asked the stylist about it and he said it's a good one--not only does it have a high "slip-weight" so that it doesn't weigh hair down, but it's a detangler, too. I love it.
Oh, in addition to the hair problems, how do ya like double the # of dirty towels to wash? I do laundry twice as much now!
