Hair

My hair has always been straight & fine. During chemo I had no hair. It grew back in and was slightly curly until my first haircut. Then it was straight. Then it was suddenly wavy/frizzy a couple of months ago. Odd. I'm on Arimidex which is an estrogen blocker; I'm on Ativan which is an anti depressant. As far as I know Arimidex can make people lose hair but nothing about changing texture. Could this be a good side effect??😄
