Scalp issues on medications

Hi. Just wondering if anyone has any issues while on Abemiciclib and letrozole with scalp dry patches? I’ve always had beautiful healthy hair and skin but since my diagnosis and treatment I’ve had scalp issues. I didn’t have this problem during chemo etc. but have the last 2 months. Any tips on how to resolve it would be very appreciated. I have tried several creams, shampoos etc. X
