When you think of the late Princess Diana’s iconic hair, it’s safe to say an image of her shaggy pixie cut comes to mind. But, she didn’t always don the look she’s so associated with today. As Lady Di obsessives (or avid fans of The Crown) know, Diana Spencer married Prince Charles when she had just turned 20. Though she had longer hair when she was a teen, by the time she got married, she had a version of the style she kept throughout her marriage — a decade spent in the unrelenting public eye. Throughout the ’80s, the Princess wore her hair primarily in the feathered variety with side-swept bangs that so instantly come to mind at the drop of her name.

Naturally, the level of public scrutiny Princess Diana’s every move was subject to meant any hair changes had to be carefully considered. “Whatever I did to her hair became front page news,” her stylist, Richard Dalton, told Town & Country in 2018. “We had to be very careful. We had to do it one-fourth of an inch at a time over several weeks.”

Later in her life, star stylist Sam McKnight became the man behind her look and made some changes, which she famously referenced in the interviews that comprise the 2017 documentary Diana: In Her Own Words. When asked about turning points in her life in which she went from “victim to victor,” Diana replied: “I suppose last summer when Sam cut my hair differently, it let out something quite different.”

In McKnight’s book, Hair By Sam McKnight, which came out in 2016, he reminisced on his time working with Diana, which started when he met her on a cover shoot for Vogue. He writes: “As she was leaving Diana asked, if I had free reign what would I do to her hair. I suggested cutting it short and she, to my surprise, agreed, and we did it there and then.”

Princess or not, any woman understands the power of a new haircut.

From the softer cuts and pushed-sideways-bangs of her 20s to the blunter cuts (and bangs) that sharpened her features as she came into her own as a beloved humanitarian (and no longer a woman married to a future King), these are some of Diana’s most notable styles throughout her life.
