Thank you for not considering ad spam. I know some people whose work I respect, who have the worst ads on their sites. I'm going to make time to ask them if they're getting paid well for those terrible ads, and if they're aware how bad it makes their sites look.
If you can identify some quality resources for people who are going bald, you might reach out to those people and see if they'll buy an ad spot from you. That's how it used to work, and with a high quality site that's getting views, that approach might work.
