Re: Should hair be clean or "dirty" when you relax?
"yes and no", IMO.
You don't want to have so much product throughout your hair that it interferes with the processing. But at the same time you don't want to strip all the natural oils that form a barrier on your scalp. That's why I clarify 3-7 days before the relaxer. That gets rid of excess products, but it gives your scalp time to replenish itself. Plus you're less likely to burn because of little microscopic tears on your scalp from washing, if you wait a day or two.
