Answer 1

The error occurs because you're telling Retrofit that you're expecting a JSONArray but instead you're getting a JSON object. I took a quick look at the result that you're using and it looks like it returns a JSON object and the returned object then contains the list you're interested in accessing. I can help you further if you post your GET call.

Answer 2

You should wrap your list of objects with one more java class
public class Response {
private boolean success;
private int code;
private String message;
private List<Data> data;
}
public class Data {
private List<Hairdresser> hairdressers = new ArrayList<Hairdresser>();
}
to generate this objects automatically you can use service like this one
