Every time I've ever gone to bed without drying my hair properly (or walked around with wet hair for longer than about 20 minutes) I have had a bad cold or sore throat the next day!
When I looked it up online, everything pretty much said no, it won't make you have a cold, but might cause a stiff neck. I know the answer is, just dry your hair properly, but I can't always- it's really thick and takes SOOOO LONG! It can't be a coincidence- wet hair gives me a cold!
So anyway, anyone want to tell me what they disagree with the internet about?
