The Pentagon announced that female soldiers will be able to grow their hair long, color their nails and don earrings.

Revisions to army grooming policies expanded the number of hair styles women can adopt, including wearing their hair long.

In the past, women with longer hair had to tie it in buns, which many said was uncomfortable and interfered with their helmets.

Under the new policy, long hair needs to be worn in ponytails or braids in training and tactical situations.

And, on the other end of policy, women who want to shave their heads - the way some male soldiers do - are now permitted. Before they had to maintain a minimum hair length.
