Earlier this month, K18 brought its viral Hair Flip Challenge to New York City’s Grand Central Terminal, turning the iconic transit hub into a buzzing social playground that benefitted HairToStay.

Hosted with Cole Walliser, GlamBOT director, the pop-up invited everyone to flip, pose, and capture fun hair moments for TikTok and Instagram.

While the Guinness World Record™ attempt was a playful challenge, the real win was the impact: K18 donated $100,000.00 to HairToStay, a nonprofit providing low-income cancer patients access to scalp cooling treatments to reduce hair loss caused by chemotherapy.
