Shaved eyebrows don't fit the dress code

From Mainichi:

Hishikari Junior High School officials said the four girls had either shaved their eyebrows or cut them too short to be acceptable.

Teachers pointed out the girls on the morning of the April 6 ceremony. The girls were told that their eyebrows were unacceptable.

"In a pre-enrollment meeting, I explained the school's requirements regarding appearance and uniforms, but they did not abide by these instructions, so I decided that it would be difficult for the four to take part," principal Toshinori Hoka said.

Were the eyebrows completely shaved off? Or were they just thinned out, like lots of women do here in the US? Seems like a weird rule either way.
