Kate Middleton always looks put together and stylish, so it's no surprise that her hair is the stuff shampoo commercial dreams are made of. The new Princess of Wales is known for her brunette waves, which never fail to look perfect every time she's photographed.

Aside from the occasional addition of some highlights, Kate's hair hasn't changed much since she met Prince William. For the most part, she's kept it a little longer than shoulder-length, and it always looks full, thick and shiny. While the bouncy blowout seems to be her preferred style, the royal also experiments with elegant updos, high ponytails and some detailed half-up hairstyles that never fail to impress. Here's a look at Kate Middleton's best hair looks through the years.

Back in 2005, when Kate first started dating William, she went to his graduation ceremony at St. Andrews University. Even before becoming an official member of the British royal family, Kate was sporting effortlessly chic styles. Her low-maintenance look featured a darker shade of brown, side-swept bangs and a flattering shoulder-length cut.

In 2010, when Kate and William stood side-by-side to announce their engagement, Kate kept her hair simple but still enviably gorgeous. She opted for a bouncy blowout (which has since become her signature look) and some longer side bangs and layers.

For her wedding to William in 2011, Kate opted for a classic hairstyle, and, as expected, not a strand was out of place. Her hair was pulled back into a soft and wispy half-up 'do that looked put together without being fussy, along with some loose curls. Kate's now-iconic Cartier halo tiara and a long veil finished off the look.

Photographed during her first official visit to Cambridge, Kate showed off a new cut that proved she was years ahead of the curtain bangs trend. The blonde highlights brightened up her hair, and the overall look was chic and just different enough without being a huge change.

While on their Diamond Jubilee Tour of the Far East in 2012, Kate twisted her hair off of her shoulders and into an elegant braided low bun. She turned the simple look into a head-turning style by embellishing the updo with pearl studs.

Kate rarely wears a hat without doing something interesting to the hair underneath it. While celebrating the 60th anniversary of the Coronation of Queen Elizabeth II at Westminster Abbey in 2013, the future Princess of Wales went with a half-up style with some of her considerably darker locks pulled back into a subtle twist.

While attending the East Anglia's Children's Hospices Norfolk Capital Appeal launch event in 2014, Kate went for a more casual look with a thoughtfully mussed ponytail. With the right amount of volume at the roots and just enough texture throughout, it was the epitome of a perfect pony.

At the 2015 Cricket World Cup event in 2014, Kate kept her hair down and wavy. Instead of just a classic blowout, though, she had some pieces pulled back into a fun twist with some volume at the roots. The result was slightly more casual but still sophisticated.

Kate went with classic voluminous waves while visiting Portsmouth, England in 2015. She kept things sleek up top while the ends of her hair were curled to perfection.

Kate often adds an interesting detail to her updos, and this braided look for the 2015 St. Patrick's Day parade in England was no exception. The twisted bun sat low at the nape of her neck to leave plenty of room for her hat.

While many of Kate's hairstyles appear loose and effortless, her 'do at a reception during a 2016 tour of Canada was polished and sleek. Pulled back into a side chignon, it gave off a more mature and sophisticated look that was just right with her red dress.

Kate's hair is almost always on the longer side, but at the Queen's birthday party in Germany in 2017, she showed off her trendy lob cut. She accentuated her new style with simple shiny curls.

During the 2017 Trooping the Colour parade, Kate skipped the blowout in favor of pulling her hair back into a twisted, voluminous chignon. The style is one of her go-tos, likely because it works so well with a hat.

While making an appearance at the 70th EE British Academy Film Awards in 2017, Kate pulled her hair back into a loose low updo that looked both regal and glamorous. Sleek but not stuffy, the hairstyle put all the attention onto her large statement earrings and off-the-shoulder neckline.

At the wedding of her sister, Pippa Middleton, in 2017, Kate opted for a low chignon with lots of complicated-looking twists and a truly interesting shape. The style perfectly matched her pink fascinator.

Kate was the picture of a princess at the State Banquet at Buckingham Palace in 2018. The future princess paired a gorgeous Alexander McQueen gown with the sparkling Lover's Knot tiara, one of the best-known British royal family tiaras (it was also a favorite of Princess Diana). Kate's simple low bun looked elegant while keeping all eyes on the statement-making piece.

For a Remembrance Sunday Service in London in 2018, Kate put a twist on her staple chignon by adding a thick braid. The hairstyle was appropriately regal for the occasion.

While visiting Cardiff Castle in Wales, Kate took a break from her sophisticated updos and wore her hair in a more casual style. She pulled her loose, shiny curls off her face in a half-up style with some volume on the top.

While visiting Ireland with Prince William, Kate decided to play around with a hair accessory, which she rarely does. The future Princess of Wales went for her usual wavy blowout, but added a chic black velvet headband that showed off her sparkling diamond earrings.

Kate chose a stylish but playful look for an event at Evelina Children's Hospital in London in 2020. Her loose curls were pulled back into a half-updo that featured a fishtail braid at the roots.

During a visit to Ulster University Magee Campus in Northern Ireland, Kate pulled her hair into a voluminous high ponytail. It was the perfect look to complement her sophisticated purple pantsuit.

Kate turned heads for her first look of her Caribbean tour with William in March 2022.

The hairstyle was just right with her shimmering hot pink metallic gown by British brand The Vampire's Wife.

Kate switched things up with a sleek and straight look when handing out an award on behalf of Queen Elizabeth at the Design Museum in London in May 2022. She pulled back her face-framing pieces for a "grown-up chic" 'do, as her personal hairstylist Richard Ward described the style.

Kate debuted a new fall haircut when bringing her three children to school in September 2022. The shorter style featured added layers and some touched-up highlights.
