Daily Mail reports, He's the 5 Seconds of Summer rocker known for his often-changing hair colour.
But on Tuesday, Michael Clifford appeared to be benefiting from laying off the dye as he arrived at The Highlight Room in Hollywood.
The 21-year-old guitarist's blond hair looked thick, healthy and full just a year after he appeared to be balding during a trip to Sydney.
The Australian heartthrob, who joined 5SOS while still in school, was joined at the venue by his longtime girlfriend Crystal Leigh.
Despite wearing a backwards-facing cap, it was clear Michael's hair was looking in a lot better shape than it did 12 months ago.
The musician has been colouring his hair for several years, which may have damaged his hair and caused some thinning last year.

In 2013, Michael opted for a two-toned hairstyle by dying the sides of his hair peroxide blond with a black middle.
Later on, Michael coloured his hair bright blue, before going completely purple.
And when he met Ellen DeGeneres in late 2014, the Sydney-born star was seen with yet another bright shade.
In June 2016, the effects of his peroxide and repeated colouring were clear, with his hair looking patchy and thin at the front while attending an event in Sydney.
Some fans even began questioning if the young rock star was balding prematurely.
However, it appears Michael stopped dying his hair around nine months go and he is enjoying the benefits of a more natural approach.
