Indeed, I was on ADT (Eligard) for 12 months. (started it just prior to SBRT radiation x5 treatments) My total testosterone levels were consistently less than 10 while on the Eligard treatment. That’s the main mechanism behind the hair loss, a major decrease of testosterone in your system. I looked like I had gone to a pre- swimming meet party where the whole swim team shaves down before the event. As mentioned previously by another my leg hair, arm hair, chest hair, armpit hair, pubic hair, all almost disappeared completely. Only had to shave every 2 to 3 days…minimal head hair loss. Of note, approximately four months after completion of ADT I restarted low-dose testosterone therapy.(I have a history of testicular cancer(30 years ago) and only have one testicle. As a result of that my endogenous production of T was very low. It took about six months before what I considered to be normal hair growth to return after restarting testosterone. Hang in there, and best of luck in your journey!
