Kate Middleton, Princess of Wales has officially gone blonde. While we caught glimpses of her lighter toned hair last week while she was on the way to church, it was not possible to confirm the exact shade of the hair as we saw her through the car window. But today, as the royal couple visited the newly renovated gardens at the Natural History Museum in London on 4 September 2025, her brand-new blonde look was on full display.
Her signature long waves looked shiny and voluminous with soft curls towards the ends. It looks like she has opted to go for a muted blonde with shades of soft golds and browns still visible as an undertone.
Photographs of her striking new look certainly took fans by surprise online with several people even speculating if they are extensions or even a wig. Regardless, the her new look if refreshing and the long blonde locks look lovely on the princess.
With her big bouncy curls and thick long lengths, there is no doubt that Kate Middleton's hairstyles always look perfect. Her glossy long locks have got people wondering, does the Princess of Wales wear hair extensions to enhance her natural hair?
A lot of hair experts and stylists have commented on Kate's hair transformations over the years and that her hair can appear thicker and longer in a short space of time.
When comparing her hair from over the years, there's definitely been a huge change in her the thickness and length of her hair. Here she is below in 2007 compared with 2021.
Comparing these two pictures, it's understandable why some hair experts have speculated that the Princess of Wales wears extensions in her hair.
It's worth noting that the first photograph was taken before she and Prince William got married, so it's likely a professional hair stylist has played their part in getting her hair in its best condition to enhance the length and thickness.
Does Kate Middleton wear hair extensions?
While we think it's very unlikely Kate wears hair extensions, any hair pieces or extensions that she might have worn over the years are very subtle and not noticeable and the colour and condition is matched perfectly to her hair.
Anyone who has previously worn hair extensions will know how difficult they are to maintain and how much they can damage your scalp. Not only that, but they can be difficult to hide too. With all the photographs taken of Princess Kate, we find it hard to believe hair extensions have never been spotted in her hair if she does wear them. As well as that, Kate is always attending outdoor events where the wind can fluff up her hair – there's no doubt that in these situations, we'd be able to spot signs of extensions.
Are hair extensions bad for your hair?
While they might make your hair look longer, using hair extensions for long periods of time can damage your natural hair, as the constant tugging on your strands can cause them to snap or fall out.
Whilst hair loss and thinning hair may occur, there are plenty of products and hair growth serums which can help to make your locks look fuller and healthier.
Hair loss can also be caused by several factors, including stress, hormonal imbalance and nutrient deficiencies. Some chemotherapy drugs may lead to hair loss in some people, but not all chemotherapy causes hair loss.
Why has Kate not lost her hair through preventative chemotherapy?
The answer is that not all chemotherapies cause hair loss. For example the type of chemotherapy typically used to treat breast cancer does cause hair loss, but chemos used for treating other cancers like that of the rectum don't always tend to cause hair loss.
Kate may also have used a cooling cap when receiving chemotherapy. This works by creating a cooling effect that then reduces blood flow to the scalp. This also reduces the amount of chemotherapy medication that reaches this area, helping to prevent hair loss.
Kate's scar on her head
Some people have claimed they can see hair extensions taped into Kate's hair and attached to her scalp. Particularly on this image from 2011 where Kate has her hair pulled back.
Clarence House soon put the rumours to rest, confirming that it is actually a scar on her scalp which she got from a surgery in childhood.
This was further confirmed when the other side of her head was photographed at this same event and no tapes or marks could be seen.
