What is the scientific explanation behind this occurrence? ?

I’ve noticed that a couple curly strands of hair are appearing on both my left and right arms which initially had only straight strands. As a

 biology student, Ik that the curliness/straightness of hair is dependent upon the shape of the hair follicle, but what leaves me quite puzzled is...why is there a *sudden* change in the shape of my hair it due to some random genetic I evolving? It doesn’t matter anyway because I intend to wax it off (for the 1st time) whenever physical classes resume, but I’m just a little intrigued by it.
