Hair plays a crucial role in shaping the vibe and concept of K-Pop idols. It's commonly understood that a change in hairstyle, like dyeing or cutting, often signals an upcoming group comeback. Given the numerous hairstyle transformations many idols undergo, which ones do you find most appealing on these idols?

1. Jeon So Mi's appearance shifts dramatically with her hairstyle. With short hair, her features become more defined, lending her a bold, rocker vibe. On the other hand, long hair brings out her feminine allure, giving her a softer and more delicate look. Which hairstyle do you think suits her better?

2. When it comes to BTS' Jungkook, you're either for the short hair and staying loyal, or you're still stuck in the phase of his long hair days. Many have said that with short hair Jungkook looks sharper and younger versus when he has long hair giving him a sexier vibe. So are you for the short hair or the long-haired Jungkook?

3. Girls' Generation's Sooyoung is definitely one who has gone through her fair share of long and short hairstyles. Donning the short hair, her face definitely gets a lot smoother around the edges, in comparison to when she has long hair it's more of a femme fatale persona that comes out. Which do you prefer?

4. One of Suzy's iconic trademarks isn't just her bunny teeth, but her long straight hair. As the nation's "first love" Suzy fits that ideal type of someone who has gorgeous long, straight hair. But there was a moment when she actually went super short upon filming for "While You Were Sleeping," shocking many of her fans with the dramatic change. Which do you prefer?

5. Another idol that got the public talking was IU. Also known for her long hairstyle, when IU chopped her locks off, it definitely brought a new vibe to the beloved idol. From being the cute, adorable idol to a more mature woman full of sophistication. When it comes to IU it's definitely hard to choose which style suits her better, but what do you think?

6. BTS's SUGA and Seventeen's Woozi are among the male idols who truly excel in rocking long hairstyles. Both artists, known for their similar features, have alternated between long and short hair. The long hair lends them an aura of mystery and elegance, adding a distinct flair to their appearance. In contrast, when they opt for shorter hairstyles, they exude a more approachable and 'cinnamon roll' like charm. Which do you prefer?

To be fair, all these idols pull off both short and long hair flawlessly, but which one do you think looks better on them?
