Sadly, yes it will continue for some time after your last treatment, mine finally stopped coming out a couple months after treatment. I didn’t use a cold cap, but mine started growing back after about 3 months. It seemed to take forever, but once it started, it came I pretty quickly, and white and curly. Bozo the clown curly, lol. I had no hair left so it was easy to tell when it started coming in again.
It did straighten out a little but remained pretty white.
Did you shorten your hair before chemo? Have you been wearing a covering like a wig, or scarf?
