A new survey is out that details just how often women wash their hair, and in one state in the country, it's definitely not all that often. Is it Minnesota?

Well, no, it's not here in the Land of 10,000 Lakes. According to this survey from lookfantastic.com, the state with the dirtiest hair the country -- where women go an average of 7 days between washing their hair -- is actually down in Tennessee.

Yep, in the Volunteer State, they only wash their hair once a week. Other states with infrequent shampooers (is that even a word?) include Maryland, Colorado, Nevada and Alabama.

Conversely, the survey also found that women in California have the cleanest hair, washing it an average of once a day. Other states with frequent shampooers include Texas, Florida, North Carolina and Ohio.

Curiously, though, Minnesota, Wisconsin and Iowa aren't mentioned at all. Does that mean we're right in the middle of those two extremes? That would mean washing your hair once every 2 or 3 days. That's just a guess, though.

BTW, this New York Times article says, though, that you probably SHOULDN'T wash your hair every day. "'Your hair needs to produce natural oils,' said Juliette Dallas-Feeney, senior social media manager and beauty influencer at Birchbox, the online beauty subscription service. 'If you wash it too much, you can strip your hair of them,'" she said in the article.

So, no, women in Minnesota don't have the dirtiest hair in the country. Which begs the question, how often do you wash your hair?
