Where did this come from?? I've heard it a few times (but never round our family tables); I assume it's just another bribe/threat to make kids eat everything. Fine. But curly hair?? Usually there is some sort of science (or at least folklore, inherited wisdom) behind these things. (Fruit DOES help prevent scurvy!)
Is curly hair a longed-for attribute amongst girls? Or is this a generational thing - the influencer types seem to prefer looooong straight hair in the magazine pics I see.
Anyway, sorry, back to chain-tools and inner-toobs!
