Former US president George H. W. Bush shaved his head in solidarity with the young son of a member of his security detail who is suffering from leukaemia.
A photo released by Bush's office shows two-year-old Patrick and the elderly ex-president sporting bald heads and similar blue polo shirts and khakis. A smiling Bush sits in his wheelchair, now his primary mode of mobility, with Patrick on his lap.
The 41st president took the no-hair plunge after noticing that members of his security detail, known as the Bush Protective Division, had done the same.
Another photo shows Bush and two dozen members of his security team, all with shaved heads, with the young patient.
Bush and his wife, Barbara, lost their second child, Robin, to leukaemia 59 years ago when she was four.
Apart from his lack of locks, the former president has made a fashion splash in recent months as his penchant for colourful socks has gained traction in the media.
