Incorrect quantity and details displayed – cache issue

From Shop archive page, when I went to single product page and clicked Add to cart button, the quantity displayed in Dropdown Cart was correct. But when I clicked Back navigation on top of the browser to go back to Shop archive page, the quantity and details in Dropdown cart returned to last visit number, which is wrong. I had refresh page to get the quantity and details right. Is this cache issue? How can I fix this?
