Can someone get a hair transplant to increase density?

Hello. So say someone has a full head of hair however they don't have good density on the top of their scalp. Can they get a hair transplant to add more density? For me for example When my hair is oily I can't spike it up as my scalp becomes see through on the top and from the front of my hairline. So can I get a hair transplant to add more density? Thank you.
