Hair care for Dark Auburn Hair (colored)

[Bobbi2224]

Hi everyone! 

Every winter I dye my naturally dark brown hair (fine but quite frizzy and fluffy and crimpy) a dark auburn colour. This colour seems to be fade really quick and I am not sure why. Does anyone have any recommendations, especially for shampoo and conditioner to help protect this colour and help it last. Any hair product recommendations help but also looking for a shampoo/conditioner combo. 

Thank you!!!!

@Bobbi2224 I don't wash my hair that often only 2 times per week and use Pureology Smooth Perfection Shampoo  and Pureology Smooth Perfection Conditioner  

I also have color treated hair and noticed my hair color not fading as much.
