머리카락 보일라 means "Your hair is going to be seen" From http://adventuresinkorean.tumblr.com/post/111905931996/%EC%9C%BC%E3%84%B9%EB%9D%BC ~(으)ㄹ라 This connective ending is similar to the pattern “~(으)ㄹ까 보다.” The first clause contains a worry about a potential future event, and the second clause contains the action that should be done to avoid the situation in the first clause. However, unlike the less restricted ~(으)ㄹ까 보다", the ~(으)ㄹ라 construction is used mainly in cases when a speaker is advising a close friend or younger person. This pattern can also be used as a sentence ending without a second clause, in which case the advice has been previously mentioned, or is implied. Examples: 다칠라 조심해라! You’re going to hurt yourself; watch out! 학교에 늦을라 빨리 일어나라. Get up quickly or you’ll be late for school. 감기 걸릴라 목도리 해라. Put on a scarf or you’ll catch a cold. 서둘러라. 늦을라. Hurry up. You’re gonna be late.
