Use your fingers or a comb to part your hair. Separate it into two sides. It might help to pin down one of the sides to keep it out of your way. Move this chunk around a little bit so you can see the roots of your hair from a few different angles. Turn on a good light in your bathroom so you can get a good look at your hair. Alternately, have someone hold a lamp or flashlight above your head to give you more light. Your hair density is basically how many strands cover your head. Look at your hair roots and your scalp. How much of your scalp can you see in an area the size of a square inch?  You’re not counting individual strands, but you can get a sense of how dense your hair is by how much skin you can see.  Thick density: If you don’t see much scalp at all, you have thick hair density.  Medium density: If you see some scalp, you have medium density.  Thin density: If you see a lot of scalp, you have thin hair density. Go through this same process at another spot on your scalp. Your hair density may be different at other spots on your head. Get a friend to help you look at the back of your head. Ask them to take a picture so you can see it more clearly.
