Hair algae is just more persistent, it'll go.
Use a spare toothbrush, spin it in hair algae, remove as much as possible. Be a little careful - don't keep scraping, one lump at a time (don't release little hairs to float about the tank by being impatient in removal, in other words)
Then Excel it. It'll fade, too. Even the daily doses, spot treat them into the algae instead of tank dumping it.
