Every week my Auntie Beehive went to the hairdressers to have her hair washed, hennaed and styled. She always wore it up in a beehive. Always. Long after that style's popularity had faded among lesser mortals, Auntie Beehive maintained "her" look.
Auntie Beehive told me once how she kept her hairdo looking nice between visits to the hair salon. While sleeping, she wore a hairnet to protect it. More importantly, she trained herself to sleep on her back, without moving, for the entire night. This minimized any disruption to her hair.
If her head got itchy, she could never just scratch it with her fingers because that would mess up the 'do. So she used a special knitting needle for that purpose, carefully inserting it under her pile of hair to scratch her scalp. The knitting needle did double duty as a bookmark in the huge ornate Bible located on her living room coffee table.
