I tend to shed more at this time of year regardless of what I do, just like my dog... I figure it's just the weather/seasons doing it. I always condition right to my scalp, as I don't have problems with excessive oiliness. Conditioner only makes my scalp itch if I don't get it rinsed well enough or if there is an ingredient in it that my skin is sensitive to. I've never noticed it increasing shedding for me, although I have noticed that sometimes air pollutants (eg - smoke) do seem to increase shedding.
