The way I rationalize it is this...
The reason for limiting retwisting is to avoid weakening the roots of your hair. They advise against retwisting hair while it's dry.
I don't think that washing and retwisting my hair at this stage will matter or impact my roots at all.
My hair will be wet.
I don't coil my hair tightly and clip it.
My hair isn't locked yet.
That's my rationale. It may be completely false, but until I see a bud, I'm retwisting weekly. I cannot take going to work looking like this another week. Plus my scalp was itching a lot this week. I briefly considered washing my hair and not retwisting it last time I washed, but with my hair texture it needs as much help/training as possible.
So here we are...tomorrow will officially be 6 weeks!
