Neleke, I wouldn't be afraid of more protein. I left mine on for half an hour, and I definitely could have used a stronger treatment, longer time, or even some heat. If you didn't notice a difference, try it for longer. I've heard about the bad reactions to protein... but also that it can be fixed through good conditioning after the fact. If your hair seems limp, but not dry, give it a try. That's just how mine was. I think it sounds scarier than it is... And now you know that a bit of gelatin doesn't do anything much, so a little more seems like a safe step. Creep up on it!
