Greasy and dirty are not really the same thing .The most popular non professional shampoos and conditioners are loaded with waxes I wouldn't recommend them to anyone before during or after a color . Glad to hear that this does not seem to be an issue for you.I just usually color my hair when it's dirty as does most other stylist I know . I'm sure washing it the day before with no conditioner will be fine . F.Y.I. any one that thinks professional products are to much I have picked up product like Toni and Guy , Chi , Crew and others at Ross and T.J. Max cheaper then I could at the beauty supply whole-seller at times they also have great deals on flat irons and blow dryers that would normally be over $100.00 .
