I have read that you are supposed to weigh in at the same time everyday and I think this is true because I get up at 4:30 with my husband every morning and i weigh at least 2 pounds more than I do at 9:30 (when I get back up) So I weigh myself at 9:30 every morning to get an accurate weight.

Im sure that wet hair would make up for the difference, even tho it isnt dripping wet.
