Hm. Funny word it is… ‘Calamistrate‘
Means: ‘to curl or friz, as the hair‘ it does.
Next time someone asks you where you are going when you are off to the hair dressers you can say, “I am off to get my hair calamistrated” you can.
Exact etymology of the word is not widely known it isn’t.
Probably associated with the word ‘calamus‘ meaning ‘straw‘ it is.
Get it wrong and a ‘calamity‘ it would be. 🙂
