I don't think blood tests would make me change anything in my routine unless bica is destroying my liver, but if that was the case I would be dead already so I think I'm safe. also I don't think you can notice any difference in hair quality with bica in such short periods of time, the only thing it would do is make your scalp less oily so your hair texture could feel different but other than that idk how it would do anything else when you're already on estrogen. I haven't really noticed anything with bica but I will still continue taking cause it should still be beneficial for maximum hair regrowth
