Dramatically increased shedding on bica

Edit time! I have noticed the rate of shedding has decreased. It is still wayyy to soon to talk about if any regrowth is occurring. For people searching through posts about bicalutamide and hair loss, hopefully it stops within a week or two you as well before you make the determination to come off of it.

I'm 18 and I have been on 50mg bica daily for 25 days without estrogen. Starting about 5 days ago, I have noticed a dramatically increased rate of hair shedding in the shower and all over my bed. On strands that fall out, they often appear to have a gradient over about 7 mm where they appear to lose some darkness (I cannot tell if the thickness is reduced or not).

I know this can literally be due to a huge amount of things, but is this loss likely a result of changes in testosterone absorption? If so, would follicles that lost the hair come back after I begin E2 injections in about a month? Could this possibly be due to liver damage (I know its an extreme edge case on bica, let alone on my small dose). I plan on sending bloodwork to an online lab to check my liver function if this continues. Are there any other things that could explain the hair loss?

Sorry for not providing definitive hormone level tests to help figure this out.
