quick question, how much spironolactone can i apply?

[thinning_dude]

I have thinning all over the top of my head evenly and i want to apply spironolactone 5% Dr Lee's cream all over the top of my head. Is this safe to do so or is there a limit to how much spironolactone you can use at one time?

I've looked on Dr lee's website but all it says is to just apply it but doesn't indicate how much.

I want to apply it all over the top.

Any advice appreciated guys.
