Can you look at the hands to check for anemia?

No, not really. No you can not check for anemia just by looking at your hands. If one is very anemic with a very low hemoglobin, it may be seen more obvious- but you still don't know how low is the hemoglobin. Other people do have somewhat pale complexion- but does not mean they are anemic. Go to see your doc and have a basic blood test.
