A new study published in the journal Evolution and Human Behavior suggests that women find men with a 10-day beard the most attractive.

The photographs were then shown to a group of 351 women and 177 heterosexual men and were asked them to rate each face according to its attractiveness, masculinity, health and potential parenting ability.
The researchers found that while a five-day beard was deemed unattractive by both the sexes, faces with 10-day beards were found to be most attractive by women while both the men and women chose faces with full beards as having the best parenting ability.
