First of all, I find all of the grammar digs here very amusing - I have an MA in English, but even I accept that electronic communication cannot be held to the same standards as print media.
Now, the real reason I viewed this posting is because I was given a perm yesterday that did not seem to "take", and I wasn't sure how to proceed. The stylist also gave me a vague, "Don't wash it for a couple days," so I was looking for an official ruling. However, the postings on this site have left me with more questions than answers, so I suppose I will have to look elsewhere.
I will leave my own advice for the other hesitators, though: If in doubt, stick with hot rollers. Allow the rollers to cool completely before you remove them, and your curls should last longer.
The salon, by the way, did offer to re-perm my hair in a couple of weeks using tighter rollers. We'll see if that works...
