Getting my eyebrows done = 修眉 (xiū méi); how do I use this?
刮眉毛 is grammatically identical to 修眉毛. They are both an action. The only difference is in the meaning. Therefore, you can use 修眉毛 in the same way as 刮眉毛. Here is some examples:


你好，我想修眉毛。 (Hello, I want to 修眉毛) 
你好，你们这里可以修眉毛吗？ (Hello, do you offer
修眉毛 service?)


The following also make sense grammatically:


你好，我想刮眉毛。 (Hello, I want to 刮眉毛) 
你好，你们这里可以刮眉毛吗？ (Hello, do you offer
刮眉毛 service?)
