itchiness

So I'm not sure how to say without sounding really inexperienced, but the area around my vaginal entrance (labia minora i guess?) seems quite itchy sometimes, not constant all day and not everyday, but it's incredibly itchy, like the kind of itch you have to pinch, and I'm not sure if it's more red than normal, especially since I don't think to check until ive tried to stop the itch. Is it likely to be anything serious developing or just irritation from hair?
