Yesterday we posted the sexiest facial hair on guys. Today, a study has come out about the sexiest hair on ladies and guys.

So, today is hairstyle appreciation day. Do they really have a day for everything?

Anyway, men and women were asked to rank the sexiest hairstyles on both sexes.

For women, the sexiest hair is when it is down and straight. Down and curly ranked as the second sexiest.

The least sexiest was hair that was unwashed, dyed unnatural colors or was up in a bun.

For men the sexiest hair was the 'just got out of bed' look. Followed by neatly combed hair.

Not sexy hair was considered to be greasy, unkempt or too perfect.
