The Neighbors 2 star, 28, showed off platinum tips with deep brunet roots on the sides — an everlasting boys' beauty trend popularized by fictional '80s baby Morris. The quippy high schooler worked his reverse ombré locks throughout the hit series' four-year run (plus a spinoff college year).

Efron, meanwhile, rocked his new 'do (and a "hustle kindness" sweatshirt) while visiting a class of preschool students on Thursday. He shared multiple pics of himself posing with the young boys and girls, one of which he captioned, "#Squadgoals." With another, he added, "Thanks to the 'Smiling Sons' class for reminding me what's important in life. Just be yourself and play hard."
