Curl : Read headers from a file and use them in a cURL command

I have a bash script with the following curl command : curl -v -X GET https://example.com -H ~/Desktop/headers.txt -o ~/Desktop/file.txt When i run the bash script i am getting unothorized 401. Obviously i am not reading the header file correctly. My header file looks like that "Authorization: Bearer 40bsafsdgds34234....". My curl version is 7.26
