I dont know how true this is but I saw it around a few places so decided to post it up here. The fan account goes like this: the girls were recording for Inkigayo and Yoona’s hair hit her in the eye and Seobaby was so shocked/surprised she cried. It wasn’t too serious but the pain shook Yoona a bit and she stopped dancing. Recording was paused for a bit.
By hair? Maybe the account was lost in translation but I’ll definitely need to find some more confirmations. Here’s a picture though, credits to dorkiiilove. She THINKS this is the picture of Yoona after the accident. Looks like it though since the girls are surrounding her.
SNSD Korean 
It could probably mean someone elses hair that had flicked her in the eye during a dance move since they are swinging around a lot. A flick in the eye hurts and can make you tear up from experience.
ohh someones hair makes more sense. had that happened before too, not fun
=]
Hope our YoonA is a-okay though. =]
The inkigayo performance was brilliant.
Taeyeon + Seohyun hwaiting!
OOH,, poor YoonA.. Thanks God that it wasn’t serious..
Ouch!
WOAH! what a coincidence, same thing happened to me today i was in gym playing volleybal and then my all my hair got into my right eye….
always wear a ponytail during gym, or a bun
well, that’s not what i’ve heard lol…
it turns out that yoona’s hair seems to get caught by seo’s ring..
and some of yoona’s hair come off… that’s make her stop her performance…
it must been really really hurt..
neways, thank God she’s fine…
awww poor Yoona….would it be possible that Seobaby’s hair hit Yoona hence why Seobaby was in shock and crying?

Haha, I wonder which ring was it? The 2000 won ring (YongSeo Engagement Ring) or their SNSD member ring.
Glad that she is unharmed though.
