How do waves relate to this? Please write using simplified Chinese characters.

I've been reading a short story in Chinese, with the task to translate it. Here's the passage I'm having trouble with:


  ‘看了，看了，他的那个女朋友真不像话，见他在报上登了几篇小说就主动爱上了他，课知道了他是一个清洁工，并打算干一辈子，就又甩了人家，真太可恶了。’
  左边的那位留波浪式发的抢看回答。


There are two issues I have with this piece. What I'm having trouble understanding is that last sentence:


  左边的那位留波浪式发的抢看回答。


I understand the meaning of this sentence, which is that the girl on the left was the first to answer. However, what role do the following bits of this sentence have?:


留
波浪 (wave?)
式发


To be honest, it's probably just another Chinese proverb I'm not aware of.

Thanks!
留 means 'maintain' ; 'keep'; 'grew (of hair or beard)'
波浪 means 'wave'
式 means 'style'
发 means 'hair'

波浪式= wavy style
留波浪式发(型) = has wavy hair (style)

It is common to identify someone by something unique in his or her appearance, like hair styles, clothes color, etc.  when we don't know his or her name
