Yes, there are hair cream removers you can use. Something that would keep the hair away for even longer is having it waxed.
You could also try laser hair removal. It's expensive and a bit painful, but it would significantly reduce the amount of hair permanently. It works best for people with darker hair and lighter skin since the laser looks for the color contrast. If you do laser hair removal, you'll probably use a lidocaine cream 30 minutes before the treatment. It basically feels like a rubber band snapping on your skin. Laser hair removal requires several treatments to work.
Another option is electrolysis. This requires more time per session and the back is a pretty large area to do. This involves sticking a needle into each follicle and electrocuting the follicle to kill it. Electrolysis doesn't require the contrast in color. I would recommend laser hair removal over electrolysis.
