Romain Grosjean
Romain Grosjean has thankfully sorted his hair out in the last decade, as the Frenchman was looking more like Shaggy from Scooby Doo than a racing driver in 2009.
'09 was the year when 22-year-old Grosjean made his F1 debut, replacing the outgoing Nelson Piquet Jr. midway through the season.
Grosjean wouldn't be retained for 2010, instead returning to GP2, where he'd win the title in 2011.
RoGro has been in F1 ever since 2012 but has stated he'd like to continue in the series until he's 40, which he turns in the year 2026.
Kevin Magnussen
Kevin Magnussen has lost his braces in the last ten years, and he's gained a decent F1 seat in Haas.
In 2009, when he was 16-years-old, Magnussen was competing in Formula Renault 2.0, a series he'd go on to finish second in the driver's championship.
KMag was made a part of the McLaren young driver programme in 2012, earning his debut two years later. The Dane has been at Haas since 2017 and has established himself well at the American team.
