Hi everyone,

I color my hair every two months or so (from medium brown to a darker brown) and by the fifth or sixth week, it has faded quite a bit and starts to go down brassy lane.

I shampoo with Elucence maybe twice a week, tops, and otherwise wash my scalp with Tresseme naturals conditioner since I have to wet it daily. Any other suggestions to keep my color from fading so quickly? Is this possibly due to the conditioner? Also, it isn't the sun...I am inside all day.
