Tutorial on the retro bun:

The source of inspiration for this hairstyle is grace, natural and authentic beauty which are the source of inspiration. It’s an iconic hairstyle revisited.

Tutorial for making the bun:
For the bun, the hair is first straightened, then a serum is applied to bring shine and a silky appearance. A center part is drawn through the hair, which is then rolled inward and tied into a low bun. On either side of the face, strands are twisted and then tucked into the bun. Final touch to perfect the hairstyle: a few sprays of mineral powder setting spray. To add a glossy touch and ensure a good hold for the hairstyle during the show.
Some hairstyles are accessorized with tiaras, crowns or other head jewelry.
