Hair styles
Hairstyles were a big deal during Ancient Roman times. Women often spent a lot of time each day having their hair tended to. It was very popular to wear your hair in upswept-ornamented hairstyles. You would also wear hairpieces to thicken and/or lengthen their hair.
Wooden hair sticks or combs were also worn in their hair. They'd even use the combs to comb their hair out during the day.
Just like the regular worn garnments, hairstyles for the married and unmarried differed.
Young women: They would wear a bun at the back of the neck, coiled into a knot at the top of the head. The hairstyles they would sport would be pretty simple in comparison to married women.
Married women: Their hairstyles were more complicated versions of the simple styles (i.e. more intricate tied buns, they were also definitely more decorated [with jewels or pins, etc.]). At first, they would keep their hair tied up tightly with ribbons on the crown of the head. But as time went on, that style disappeared (but some priestesses still used them).
But all women shared a common liking for hairpieces, wigs, lotions, and dyes. In fact, blonde hair was actually very popular and sought after.
