Zayn, 30, first began sporting his buzzcut way back in 2015 after he sensationally quit One Direction during their tour.
Zayn is currently growing out his hair and shared a photo of his blond locks to his 50 million followers on Instagram on Friday.
Harry last posted to Instagram in July when he shared a compilation of best bits of himself, his fans, and his staff from Love On Tour.
Harry and Taylor began dating in June 2023 and became official in August.
Since then, the pair have enjoyed various outings together as they take their romance to new heights.
The two have spent some time together in London where he has introduced to her to his famous friends, particularly best pal James Corden.
The Watermelon Sugar singer reportedly ‘sees a future’ and is ‘head over heels for Taylor,’ a source revealed to Us Weekly last month before noting that he ‘loves spending as much time with her as he can.’
While out with Taylor, 29, and a group of friends, the three-time Grammy winner was spotted sans his signature haircut while listening to the Irish rock band perform their greatest hits.
During the concert, Styles wrapped his arm around his lover and reportedly spent the night exchanging ‘a lot of little kisses’ and taking selfies together, according to TMZ.
At one point, their friend group danced in a circle ‘toward the end of the night.’
The singer was previously linked to actress-turned-director Olivia Wilde for two years and the two split due to different priorities.
Zayn is now single but was famously engaged to Little Mix’s Perrie Edwards, a fellow X Factor alum.
The singer revealed this summer that he was single by choice to focus on being a great father to Khai, 3, his daughter with American model Gigi Hadid.
He began an on-again, off-again relationship with Gigi Hadid in late 2015, before splitting for the final time in 2021.
Gigi starred in his music video for his hit debut song ‘Pillowtalk’, and the pair appeared together on the August 2017 cover of Vogue.
They share daughter Khai, born in September 2020.
