Hey guys, I'm new here. I've been taking testosterone since then age of 19 years old, i'm 23 now and over the last year in particular i have been really thinning on top and hairline is receding/thinning too.
That is not an wildly unusual time for a man to begin going bald. Most of us have gray hairs and some receding hair by our thirties, though it is often is not noticeable to anyone but a barber.

Many transsexual males start balding after the 4 year mark.
Is there documented evidence of this? I'd be very interested in reading this article.

From a genetics point of view transsexual men should be less likely to go bald due to the fact we typically have two XX chromosomes and since the baldness gene is thought to be recessive and carried on the X chromosome. Our other remaining X chromosome should copy out the recessive gene and dominant it. (this is why having two XX chromosomes is a good thing with regard to undesirable recessive genes)
This means that in order for a transsexual male to go bald he would need to have the baldness gene carried twice on both his X chromosomes.
There are several such genes, not all of which are X-linked, and not all of which have been identified. Remember the awful rule of human cellular biology: anything could affect anything else and very often does. Additionally, possible interactions with estrogen-activated pathways may also play a role in FTMs.
The likelihood that this will be empirically investigated in transmen in the foreseeable future is, of course, nil. The cost of genetic engineering research is simply extraordinary; many of the fluids required as media are not synthesizable and must be extracted from such things as amniotic fluids of animals, and the people capable of withstanding the education needed for such research are extremely rare. You should hear some of the crap that my friend Dr. K has to wade through just to install a single gene in a cell line... Some true 'Tales from the Lab' come out of that building.

DHT is the hormone responsible for causing baldness as it converts testosterone to DHT in the hair cells. The presence of DHT in the hair cells causes the bodies immune to attack the cell killing it for those of us genetically predisposed to balding.
The hypothesis that alopecia androgenetica is an autoimmune process sounds very suspicious, to me. I'll check with Dr. K, but I was under the impression that the process does not involve autoimmune responses.

You see even for those cisgendered men who are not genetically predisposed to going bald will go bald regardless if DHT is high in the body. This is certainly true when bodybuilders take testosterone and go from having healthy hair to weak thinning hair. The extra testosterone and DHT triggers the onset of balding.
These sentences seem to contradict each other; you stated that we will go bald regardless of DHT levels, then provide an example of baldness due to DHT levels. Did you miss a qualifier in the first sentence?
I think that your hypothesis, what little I can glean from your post, lacks evidentiary support and may not consistent be with the known mechanisms of human biology. If you could provide a study of this condition (which might be called alopecia pseudoandrogenetica, I suppose), we can proceed from there. Otherwise, you might want to start a survey on the topic; I imagine that you could do so with very little funding through your local university or medical school, if you have academic standing, or you could search for medical researchers on the topic and propose the study to them.
That having been said, the idea that DHT levels in transmen are heightened would account for a great deal, and evidence of this would be easy to collect. If you have some evidence of this, it could make for a very interesting hypothesis, once the biological mechanisms are properly sorted out.
