As the title says,I am trying to connect the dots that causes the hairloss.So I am attaching few pics here:-
Picture 1-Here we can see what are the no of possible causes which tends to combine and cause the hairloss.
We know that genetics play a certain role in balding and thinning of hair and also the androgens present normally for fucktioning of humam body(We can classify them as the precursors for hair miniaturization).
Now one will question,how will it do and what are the steps involved in it..Now lets see the process:-
Androgens(at a certain point) and genetics(mainly) are responsible for:-
Picture 3:-It shows how finasteride and minoxidil attacks and arrest the hairfall.
Clearly we can see here that finasteride attacks the androgen response(dht response) to the inflammation which increases the tgf beta-1 cytokine and then that eventually causes blood vessel calcification,fibrosis and dermal sheath thickening.By attacking the dht it inhibits the tgf beta 1 to reduce it and also stops binding the dht to the scalp follicles and and eventually stops the hairfall and causes some amount of regrowth..
And minoxidil increases the blood flow supply to scalp which increases oxygen and nutrient flow eventually causing new hair growth but still fails to treat the entire cause due untreated androgen response.
Conclusion-I can conclude here that dht plays as the main important factor here.But only the presence of dht cannot cause hair miniaturization,it goes through no of reactions with other signaling proteins,fatty acids derivatives,cytokines,pro-inflammatpry pathways and causes chronic scalp conditions like calcification,fibrosis,over production of sebum etc and eventualy causes miniaturization.We can still stop hairfall at some point(without touching the dht) by inhibiting the process which dht does after binding with the proteins,fatty acis etc(like inhibiting tgf beta-1,stopping blood vessel calcification and also by stopping the fibrosis).

Now one will question,how will it do and what are the steps involved in it..Now lets see the process:-
Androgens(at a certain point) and genetics(mainly) are responsible for:-
- Chronic scalp tension(which includes skull bone growth,chronic contraction etc)
- Now this leads to chronic inflammation(ROS,COX-2,IL-1,TNF-ALPHA and also TGF-BETA 1)
- But mainly the chronic inflammation occurs by increase in tgf beta-1
- Now interestingly,dht also response to this chronic inflammation and also cause increase in tgf beta-1
- Now this dht cause increase in overproduction of sebum where scalp is oily but people also tends to have flakes and dandruff where scalp tends to be dry(These are both caused by overproudction of sebum)
- Ok so now this increase in tgf beta-1 and dht(responding to other pro-inflammatory pathways,proteins,fatty acids etc) causes:-Blood vessel calcification,dermal sheath thickening and perifollicular fibrosis.
- Now this blood vessel calcification causes fat deposition,dermal sheath thickness causes decrease of blood flow which decreases the oxygen supply to the scalp and perifollicular fibrosis occurs due to overproduction of collagen.
- Now this three above factors are influenced by dht and by increase of tgf beta-1(which is also increased by dht)Now this dht response to this pro-inflammatory pathways are caused by chronic scalp tension{chronic scalp tension is due to genetics and the androgens(mainly dht) which is present in our body for normal work function of a body} and by combining all these,miniaturization of hair follicles occur.
