Show Curl POST Request Headers? Is there a way to do this?

I’m building a Curl web automation app and am having some issue with not getting the desired outcome of my POST action, I am having some trouble figuring out how I can show the full POST request I am sending over (with headers), I have been searching on this but everything that comes up is the response headers, actually I want these too but also the request, which none of the posts I find on google seem to mention..
