Mines too and I am also scare to use anything

Thankyou . So afraid to put anything in my body that is not a
whole food.. the oncologist said
Collagen would not interfere with letrozole. My skin has aged since staring letrozole one year ago

I hope so 😝. But great question! My Onco said Biotin and a Natures Way product called Hair Skin and Nails ok. So I think so.

This answers a lot of my questions. My hair is so thin, I shed constantly. Thanks and Happy Thanksgiving to everyone 🫶
