sfisher...I think you have more uniformity than you think. I just looked at your pics and your hair looks so pretty...and uniform. Maybe try the plopping-mousse-plopping thing I mentioned above. I am not sure of your hair thickness but it may work who knows?
To be really honest with you, I am more excited by the fact that I have shiny hair that doesn't feel like straw more than anything else.
I haven't had hair this shiny since gradeschool. Plus it is softer and I have discovered that after 15 years of dyeing that I really like my natural haircolor. It was a beast growing out but chopping it all off was a blessing in disguise.
