Significant hair loss using Minoxidil for beard growth (Photo)

31 y/o male. Last year read about using min 5% for beard growth 2x a day. Used Sep-Nov, the last 4 weeks scalp shedding was so extreme I had to quit. Hairline receded a half inch and temples even worse. Dermatologists i've seen have 0 answers and don't believe me. Bloodwork is normal. Lost 20-30% overall density along with recession. I know this was due to minoxidil. Been seven months since stopping. 1) Is this a min shed? 2) Telogen effluvium? 3) Did I permanently ruin my hair? Thank you!!
