It's a hair treatment for us curly girls, yes. It's pretty obvious when someone has not been doing them after having been very careful with keeping up the regiment for the better part of the past decade. There are some HQ photos floating around. You have to look to her roots and edges, not the rest of her hair - those can still be sleek and straight - but those baby hairs rarely lie when someone has been skipping treatments. I don't think we should necessarily speculate until there is an official announcement, but let's just say, there are certain 'times' when it is advised against.
So, if my haphazard guess is correct, I reckon we'll be seeing some careful hair manoeuvring and unusual hairstyles until that announcement comes.[...]
