I’ve been on TRT for 3 years.  About 3 months into it, I noticed temporal hair loss, and I developed a prominent widow’s peak.  I  didn’t actually notice any shedding (more on that later), but my hair was thinning.  I started taking finasteride, and the thinning hair stopped and eventually reversed after about 6 months.  I had no negative side effects.  9 months ago, I decided to supplement TRT with nandrolone to see if I could rid myself of pesky joint issues.  I read about nandrolone & stopped finasteride.  I replaced finasteride with Rogaine and a laser cap while on nandrolone.  10 weeks into the nandrolone, my hair started coming out in handfuls.  I had never actually experienced shedding, but there was hair all over the bathroom.  I would run my hand through my hair and have handfuls of hair.  Had never experienced that.  I stopped nandrolone.  Still shedding.  About 6 weeks after stopping nandrolone, I resumed finasteride.  It took about 8 weeks, but the shedding stopped.  At 12 weeks, I think my hair is beginning to thicken back up.  Nandrolone was great for relieving joint pain, but I don’t want to go bald.  Can’t really say if reversing hair loss was due to stopping nandrolone, resuming finasteride, or a little of both.
