Hi I am new here. I finished chemo (August 2018) and brachytherapy (October 2018) for Endometrial cancer stage 3A. My oncologist wants me to take Arimidex for 2 years. I have read about all the side effects and am concerned about hair thinning and loss since mine is growing in now and I am afraid of losing it again. Are there any shampoos that really prevent hair thinning? I read about topical 5 alpha reductase enzyme inhibitors online. Any information would be greatly appreciated.
