Is it possible for hair to become weaker and thinner if it doesn't shed? I thought miniaturization happens when the next hair growth cycle brings weaker and thinner hair than before, but a bunch of people are telling me this isn't always the case and hair can miniaturize right on the scalp. Is this true?

No, hair has to go trough a hair cycle to become weaker the next around due to DHT -

Damn, another thing to be anxious about.Comment

Really? My hair must not have gotten that memo. It thins all the way down the shaft.
...Really though, you think DHT only acts upon hair follicles during the resting phase?

Of course not, but it seems strange to me that DHT would affect already grown hair. How would that work? Would said hair cease to receive whatever nourishment it was receiving before? It really seems odd to me. And I usually hear that even most aggresive forms of MPB need a couple growth cycles, over the course of which the DHT-affected hair sheds and then comes back thinner, shorter, weaker etc.Comment

I'm not sure I fully understand what you're saying.
But doesn't it stand to reason that if DHT (or some other related process) is damaging/shrinking the hair follicle, that it might continue to produce hair (e.g. the hair would continue to grow) even as it shrinks? The result being that the end of the hair shaft near the root is thinner than at the end.
I wish to God it didn't shrink as it grows, but I can tell you from personal experience (just by looking at my own hair) it absolutely does. And I don't just mean the 2-3 weeks shift from catagen to anagen.Comment
