He made headlines when he debuted his newly-shorn head at an engagement last week.
But it appears Prince William might already be having second thoughts about his dramatic new look.
The Duke of Cambridge, 35, was spotted sporting longer and thicker hair on his sides at a public engagement today, in a sign he will let the style grow out slightly.
London hairdressers Hershesons recommend trimming a buzzcut every week in order to maintain its optimum length and style.
Growing out? Prince William’s hair appeared noticeably thicker at an event in London today
Shorter style: The prince, 35, debuted his closely shaved look at an event last Thursday
Images taken at the Charity Commission’s annual public meeting in central London today reveal noticeably thicker hair at the side of William’s head.
The third-in-line to the throne, whose hairline has been receding for several years, decided to brave the shave ahead of his visit to the Evelina London Children’s Hospital on Thursday last week.
Prince Harry has been known to tease his older brother about losing his locks; while chatting to a Second World War veteran in Barbados several years ago, Harry remarked that William ‘was already bald aged 12’.
In 2014, the Duchess of Cambridge suggested the perfect solution for her husband’s growing bald patch – an alpaca toupee.
Bookmakers William Hill are now offering odds of 6/4 that William will go for a totally shaved head for Harry’s wedding.
Although the odds are 1/2 that he will stick with his new buzz cut, punters can also place bets on whether the future king will have a hair transplant, with odds of 16/1.
Speaking at the event today, Prince William told how his parents taught him about the importance of charity work while he was growing up.
Outlining the royal family’s deep dedication to charity work, William said: ‘My family have not done this because it looks good – they do it because charity is not an optional extra in society.

He told of how his mother Princess Diana took him to a homeless shelter as a young boy, above
‘We believe that, above anything else, charities nurture, repair, build and sustain our society. Without the work that charities do, society would be an empty shell.’
He spoke of how his mother Diana, Princess of Wales famously took him to homeless shelters as a child and explained to him ‘why people I met there matter’.
But he also said of the Prince of Wales: ‘From my father, I learned how central charity was to his life, his sense of purpose.
‘The Prince’s Trust is not an arms-length organisation for my father. He cares deeply about The Prince’s Trust because it is a living projection of his values.’
‘As a young child, I recall evening after evening my father’s diligence and compassion as he applied himself to answering thousands of letters and reading endless reports in order to stay on top of his ambition to do all he could to help the underprivileged.’

William added: ‘Without my realising it, what my parents were doing was instilling in me and Harry a lifelong habit to put charity at the heart of our lives.’
The Duke also paid tribute to his grandparents, the Duke of Edinburgh and the Queen.
‘My grandfather Prince Philip has been one of the most tireless public servants of this country, deeply committed to helping young people fulfil their potential,’ he said.
‘My grandmother the Queen has never given a Christmas broadcast without paying tribute to charitable organisations, volunteers and people who care for others.’
William said the challenges faced by the charitable sector were not dissimilar to those faced by ‘other age-old institutions such as the Monarchy, always seeking to ensure relevance and public service’.
