Is thinning hair always miniaturized?

Does miniaturized hair gradually grow shorter with each cycle or can a miniaturized hair be long, say 5-6 inches then fall and stop growing?

At the start of the year my hair was thick but after a stressful couple of months, all my hair turned super thin with bald patches. The hair turned so thin it has very wide partings. Also all my body hair thinned too. Beard, arms, legs and pubic area. It’s like every hair on my body miniaturized.  I can see my scalp now with wet hair. It all happened quickly, this wasn’t a gradual thing. The hair texture feels weird. My beard hair has thinned the same. I had thick hair on arms and legs now it’s all very fine. My pubes are now thin and wispy.  I started taking fin a few months ago. I was prescribed it for prostate. Will this help? I can’t find anything about this when searching the net, only TE but does hair thin during that? At the start of the year I was very stressed, hardly eating or sleeping for a couple of months which I”m sure caused this.

Let’s imagine a hair that grows out for two years and is 12 inches long. If miniaturized started into the second year, the hair closest to the scalp would be thinning then the hair at the end which was made 2 years earlier. So a miniaturized hair can be seen simply by pulling out a long hair and looking at both ends. Another aspect of these miniaturized hairs is that they will grow slower and slower over time, eventually they stop growing and just stay there, falling out with washing, brushing and just the wind.

There is another condition that I just recently defined in the literature called Age Related Thinning. In this situation, all of the scalp hairs become thinner all at once and it is uniform thinning throughout the scalp. Although this is more common in men and women over 50, it does appear in younger men and women. I have seen it in men in their 20s and they make the mistake to think that this is balding because they can see through the hair to the scalp. There is no known treatment for this and neither minoxidil nor finasteride can reverse this as I know it.
