Help! Ponch is still grey!

I dipped a Mr. F and a Luke head several years ago, numerous times. It helped them some, but they slowly went back to gray. I did do it over the summer, so humidity may have been a factor, but if they re-gray like that, I don't see it being something to waste a lot of time on, personally. But that's just me.

So even this is not a permanent fix, then? Is that normal for them to return to gray? Must be something in that dip that rejuvinates the plastci and then seeps away again just like the original?
Basically Mego Botox?
