Hi Gillian, yes like you i had long hair that I lost after two weeks of chemotherapy, it grew back very curly and grey ( i used to colour it). It.did take a long time  , i can't remember exactly how long, but eventualy the chemotherapy curls went. And I started colouring my hair again  after 6/7mths of ending all my treatments ,8 rounds of chemotherapy, 15 rounds of radiotherapy.  So yes in time your chemotherapy curls should subside. To be honest when the curls started to drop slightly I kinda liked the subtle wave I had  but its been five years now ,and chemotherapy curls are no longer there. Im not saying it took five years ,it was before that,id say around a year and a half after  treatments ended i started to notice curls were no longer  as bad,just a nice wave . So yes you are not stuck with your chemo curls. I hope this helps.
