How long to wait to protein condition?

I permed my hair last night. My hair is almost to bra strap length and I do a spiral curl with Quantum for color treated hair (purple box) I do a perm approx. every 18 months. I don't do it more often due to fear of damage. My hair is slow growing and is a bit naturally wavy so the grow out at the root doesn't look too bad until about 18 months later.  The Quantum perm never falls out for me, it's always just as curly 18 months later. Just need to redo for new growth. My stylist used to perm me, but when I moved I was afraid to let anyone else do my hair so she showed me how.  My hubby helps my apply the waving lotion and neutralizer, but whines and gags the entire time from the smell!

I colored my hair for the first time last October with permanent haircolor so I want to do a protein treatment to correct any damage from using color and perm.  The perm looks pretty good and I have no breakage, but it does feel drier than usual after a perm. When can I use a protein treatment without worry about it pulling out the curl? I have been doing Aphogee about every 3 months and K-Pak every month followed by Loreal Mega Moisture Conditioner for about a year.

Which is best for after a perm, Aphogee or K-Pack? How soon?  Thanks for any advice.
