It's unclear if the new look is for a role or a whim, but this isn't the first shocking hair-relate change Centineo has made recently. In September he dyed his facial hair blond, causing another online uproar.
Centineo first became an online sensation for his role as Peter in 2018's To All the Boys I've Loved Before. Now he's set to take a turn to action, appearing both in the upcoming Charlie's Angels film and as He-Man in 2021's Masters of the Universe.
"It's a lot of hard work," he told ET's Kevin Frazier of his He-Man training back in June. "It's every single day, but it's really fun."
