Does hair have that much an effect on passing? Everyday at my job I am being ma'amed from the side, or back by young guys, old women, and more. My job requires me to wear a hairnet now, so that could be a reason why, and I grew my hair longer (but not below my shoulders yet).
When face to face though, I don't get that, except once when a guy said, "Sir.. ma'amed".
