my hair is both straight and curly!

[balzamico]

My hair's always been pretty straight with maybe a bit of a wave. Since the menopause (or maybe greyness) it's now curly on the underneath but poker straight on the top - its a nightmare!
I have it in a fairly short bob currently but at the first sign of dampness the underneath goes curly leaving the top layers sticking out over the top.
I'm going back to my lovely hairdresser tomorrow and am hoping she can help - maybe layers on the top parts?
Does anyone else have this issue and has found the perfect cut?
I grew out the grey so its completely natural but at 53 i'm really scared of ending up with a granny cut of some sort

I don't have any answers but the exact same thing has happened to my hair. I don't know what to do with it so I've just ignored it and I tie it up most days, until I can formulate a plan.

I've got curly hair underneath and straight on top, have always had the same.
I had an undercut and got the curls removed, it doesn't show when it's down and it makes my hair so much more manageable.
