Yoo Ah In has been garnering significant attention from the media as he faces drug charges.

All eyes were on Yoo Ah In when he made his appearance at the Seoul Central District Court in Seocho-gu, Seoul, for interrogation for a warrant review prior to a potential arrest.

On this day, the actor was seen swiftly exiting the courthouse under the protection of bodyguards. Despite the intense media presence, Yoo Ah In maintained a composed demeanor, even after being hit with a plastic bottle containing coffee on his way home.

Aside from his tired appearance, netizens couldn't help but notice the sudden presence of strands of white hair on Yoo Ah In's head. The sight of Yoo Ah In with white hair, a departure from his usual appearance, left many surprised.

Netizens in various online communities expressed their shock with comments such as, "Is that white hair on Yoo Ah In?" "Why does he have so much white hair?" "I didn't know he had so much white hair," "Is he at the age where his hair grays?" and"Yoo Ah In must be stressed...his hair..."

If gray hair has increased rapidly over a short period of time, it is most likely due to stress. When an individual is under a lot of stress, the secretion of adrenaline increases, and adrenaline constricts the blood vessels that are in contact with the scalp hair roots, interfering with the supply of nutrients to the hair follicles. Then, the melanin production does not work properly, so instead of black hair, white hair appears.

Meanwhile, after admitting to most of his charges, Yoo Ah In avoided arrest for illegal drug use.
