Princess Anne's hair is a testament to her enduring loyalty to the Crown; it's practical, polished, and has stayed the same for more than five decades.
The Princess Royal, 74, who is often recognised as being one of the hardest-working royals, has stayed loyal to her signature chignon hairstyle for most of her life. The classical up-do, created by twisting the hair into a knot and securing it with pins, has become synonymous with the royal.

The late Queen Elizabeth II's daughter rarely deviates from the sleek and elegant 'do, which she has been rocking ever since she was a teenager.
"It's like armour," Claudia Harrison (who plays Princess Anne in seasons 5 and 6 of The Crown) told Marie Claire, who added that Anne's loyalty to her perfectly executed 'do is parallel with her unmatched work ethic and undisputed reputation as the hardest working royal.

"Actually I read an article the other day about the, I don’t watch Netflix and The Crown, but the actress was talking about how long it took them to do their hair like I did," Princess Anne said during an interview aired in documentary Anne: The Princess Royal at 70, referring to actress Erin Doherty, who plays a young Princess Royal in seasons 3 and 4 of the series.
"And I'm thinking, 'How could you possibly take that long?' I mean, it takes me 10 or 15 minutes."
Erin described the process of being in the hair and makeup chair to perfect Anne's 'look' as a "beast" of a process, telling Town and Country the process often took upwards of three hours.
