Are you saying that now that i have used letrozole the damage is permanent unless i use estradiol? spironolactone and duta aren;t enough? i am fucked, i regret taking letrozole so much, it is making me feel suicidal knowing i did this to myself, sorry fit that sounds stupid but it's how i feel , my only hope was that my hair would recover in the coming months, right now im below baseline before i even started any treatments. The two months i was on letro wreaked my hair beyond belief. I never should have taken it
