Do telogen effluvium and an itchy scalp go hand in hand?

I am a 20yo male with shedding of approx. 500 scalp hairs per day since january. I have been on mincycline about a year (for acne) before hair loss started, I stopped it as soon as I noticed shedding. 4 months before the shedding started i was febrile for about a week and hence doubled my minocyline dosage. Hair loss is diffuse, eyebrows involved. No AGA in my family. My scalp is itchy and a trichologic exam. showed dandruff, but no seb. dermatitis acc. to the dermatologist. No regrowth yet.
