I was on several different aromatase inhibitors for 4 years and then switched to Tamoxifen hoping my joints would improve. My hair fell out in massive amounts. I ended up getting a "topper" that blended in with my remaining hair. I stopped the Tamoxifen and went back to Letrozole. My hair stopped falling out and slowly grew back in! Still on Letrozole for another 3.5 years. My joints hurt but I have hair!!!
I know that everyone experiences different side effects from AI's 🙁 Minoxidil works to keep your remaining hair from falling out. You must keep using it until you leave this earth.
Dermatologists can help you understand what is available currently. If you can get a few recommendations before you make an appointment, they might really help you navigate this cruel side effect.
