Girlfriend, you know I've tried everything under the sun.
I know your hair is fine and you worry about flatness, greasiness and tangles... Try some of these:
L'anza Protein Plus--old formula
Breakthru
Salon Selectives Completely Drenched
L'oreal Unfrizz Shampoo--has sles
DPL Shampoo (Used to be "Back Alive" shampoo)
Elucence (I think you tried this already...)
AllWays Natural Moisturizing Formula Shampoo--Don't laugh! Shawn likes it!
It has sodium lauryl ether sulfate in it.
Something by Jason Naturals for normal hair or "all hair types".
Something by Aubrey's other than Island Butter or Rose Mosqueta. The JAY might work for you...
Salerm Champu con Proteinas has sles in it, but I like it...
Curl Friends Shampoo--also has sles
Have you tried baby shampoo? What about one of the QP shampoos?
