It's no secret that Israeli Prime Minister Benjamin Netanyahu was quite the looker as a young man: Happy Birthday to @IsraeliPM @netanyahu, who turns 67 years young today! Ad 120 Mr. Prime Minister! pic.twitter.com/cNawRmdpkS — Arsen Ostrovsky (@Ostrov_A) October 21, 2016 It's also no secret that he has aged, sporting a more stately, silver-haired look for the last decade. Thoroughly gray. (GPO) So, it was odd when he appeared last month with the hair color of his much younger self. A darker hairdo for Israel's Prime Minister. (Abir Sultan/AFP) The new tawny 'do was a surprise to many, and prompted media gossip: Netanyahu on his 3rd hair color in 10 days. Started regular late-60s grey; then a leap to bark brown; then gunmetal grey; now mousy chestnut pic.twitter.com/jg1GWzQJuP — Noga Tarnopolsky (@NTarnopolsky) April 24, 2017 Buzzfeed noted that a week later, his hair seemed to be even darker, saying that it 'looked like he was Benjamin Buttoning.' To the Prime Minister's credit, he acknowledged the gaff in a Passover greetings video posted to his Twitter account. 'Look how beautiful it is here in nature, in the Galilee,' he said, gesturing to his surroundings. 'Everything is great, everything is blooming. A little green, a little brown, and I'm not talking about my hair color, okay?' צאו לטייל בארצנו היפה. חג שמח לכם! pic.twitter.com/FSceFYd9ls — Benjamin Netanyahu (@netanyahu) April 16, 2017 'By the way,' he continued, 'they say that brown is the new gray. But I promise within a few weeks and the gray will grow back. Most importantly, may you have a happy holiday. My, what a beautiful land we have.' It appears that his hair has now returned to its natural state. Netanyahu chairs the weekly cabinet meeting in Jerusalem May 3, 2017.
