That would definitely explain it. You probably had some degree of telogen effluvium if it came back without drugs. As of right now, I don’t see much going on in terms of active miniaturization except for a few hairs at the front. Your hairline is clearly defined and seems to have a more or less consistent density all the way across, which to me signifies stability. If you were to lose more though, I would definitely be concerned because it looks like it has already finished maturing. Any further back is headed to Norwood 3 territory,
