I'm personally no expert on this but Supergirl started a thread a while back about the use of hard core proteins such as aphogee within 2 weeks of a relaxer and stated it was a bad idea because it may cause the newly relaxed hair to revert. Do a search on hard core protein and/or supergirl and that thread should come up with plenty of good info.
It doesn't make sense to me that yoor hair will revert... if that's the case, then why doesn't your hair revert at all when you do a regular protein treatment?
I also dont think it will necessarily revert your hair. Years ago when I had a bad relaxer experience, aphogee was the only thing that stopped the breakage, and it didnt revert my hair.
