Sissi slept on a pillow with a silk cover
Elisabeth of Bavaria , the unforgettable Sissi , she was justifiably proud of the splendor of her hair , which we can still admire today in the portraits of her that have come down to us.
But you know what the secret was (one of many at least) to keep the beauty of the curls intact?
Sleeping on a pillow with a strictly pure silk cover.
That's right:silk, preventing frictions, prevented the hair from breaking, and the electrostatic effect was also reduced, so the hair did not become frizzy.
As I have already reported in several posts dedicated to her, Sissi took great care of her beauty (even too much, perhaps) and knew many little tricks to keep it for a long time ( see https://www.pilloledistoria.it/8699/storia-contemporanea/la-bellezza-sissi-presunti-flirts-dellimperatrice).
