I'm not quite a hair twin, but similar anyway.
+1 on IAGirl's gelatin PT. I love it! However, I found that I needed to add a lot more moisture to it, so it's more like a PT/DT combo for me. It worked better that way rather than following with a DT.
Also, try a sample of Ion Effective Care Treatment as an RO. Sally's sells sample packets of that. I find that if I put it in, put my shower cap on, and let the warm shower water run over my head for a couple minutes, it provides a good dose of protein & slip.
