I didn't lose my hair. I've been on HU (2 caps/day) + baby aspirin since 2021, only side effect in year one was gut issue. I'm more afraid of stroke or heart attack, than HU and ET. I never had any symptoms, just elevated platelets....I was a little frozen when I first heard cancer, but I know people who have had lot worse cancers and other conditions. All the best, I hope your journey down this road is as easy as mine has been.
