Hairfall caused by vaccine. Please help.

I am 21 years old. Never had covid. After getting covishield there has been a sudden increase in hairfall. It can't be alopecia or a hormonal imbalance. How can I get those two out of the blue at the same time that I got vaccinated.since I never had covid, I did not go through a stressful period which would cause telogen effluvium. Unlike many people I did not even feel weak or had high fever after taking any of the 2 doses.  Therefore it is highly unlikely. Even if it is then it has something to do with the vaccine only. Please help me out. This is getting very disheartening. What was the point of getting vaccinated then, if it will make me bald at such a young age. I haven't developed any patches so from outside it won't look like my hair is falling but it has definitely increased.
