Kate has been in quarantine with Prince William and their three young children, and they have been making royal appearances through video calls.
For her appearance on This Morning, she wore her locks down and curled but brushed through.
She made an appearance to speak her new photography project – the Hold Still 2020.
Fans of the royals have spoken out on Twitter, saying they’re loving the new style.
Sarah Stook said in response to the announcement of Kate’s appearance on This Morning: “Strong hair game from the Duchess of Cambridge.”
Others couldn’t believe that the duchess had done her hair herself.
An account called Lillian The Postmodern Mum vocalised their thoughts that the self-styling may be too good to be true.
They wrote: “Random thought while scrolling through Instagram: Are celebrities and royals doing their own makeup and hair due to social distancing?
“Or are makeup artists ‘key workers’?”
While it’s unclear whether Kate has been able to get a professional to do her hair in lockdown, experts believe she’s styling it herself.
Gary Kavanagh said: “Kate Middleton looks absolutely beautiful.
“Hair looks perfect especially for lockdown.”
Some however are feeling the pain of trying to recreate the style.
User @rosesandpsalms said: I” really thought I would look like Kate Middleton when I cut my hair mid length but what do I look like instead? Trash!”
Celebrity hair stylist James Johnson talked to Femail about the change
James said: “Kate’s hair is usually more full of volume and pristine.
“Here her hair looks more undone, and definitely shows signs of her doing it herself.
“Although we are used to Kate’s perfect locks, Kate’s effort is great and it’s nice to see a more relaxed style on her.
“It’s not easy doing your hair yourself when you’re used to getting it done professionally, so Kate has done well.
“Kate may have even created the blow dry look with a medium tong, which can easily be done at home.”
