Sorry you are having issues with thinning hair. It doesn't seem logical that washing with conditioner and massaging one's scalp would cause hair to fall out, but hey anything is possible!
I've been conditioner washing for many years now and it's made my hair so much healthier and happier. I have to fight hair thinning and dryness due to thyroid but my hair is still healthy thanks to CG.
--I'm located in Western PA.
--I found NC in late 2004, CG since 2-2005, started going grey in late 2005.
--My hair is 3B with some 3A, texture-medium/fine, porosity-normal except for the ends which are porous, elasticity-normal.
--My long time favorite products are Suave & VO5 conditioners, LA Looks Sport Gel, oils, honey, vinegar.
--My CG and grey hair progress --
