It was gradual. I never noticed it in the shower or on my comb in an obvious way.
I just noticed that you had said wavy course hair, mine is curly too. I believe it is more important to make sure that the hair is properly wet. I normally straighten my hair but had it cut shorter during Chemo and went back to curly. As I was told not do blow dry or straighten while going through chemo with cold cap.
I did on occasion blow dry my fringe.
The only other thing that isn't always a good look, was the regrowth if your hair is normally coloured.
I didn't wait too long after chemo to colour my hair. I'd need to look up photos to tell you exactly.
