It seems like my hair is falling out a lot more than before. Has anyone tried a scalp booster?

Lately, when I look down the drain after washing my hair, I definitely see more hair than before, which is bothering me for no reason. I thought I always tended to lose a lot of hair, but lately, it seems like more falls onto the floor when I blow-dry, and my parting line feels a bit wider than before, so I find myself constantly looking in the mirror. I don't think my hair loss has progressed severely yet, but I want to start managing it proactively. While searching online, I came across a lot of treatments like scalp boosters and Pantodil, but I don't really understand the exact mechanism behind them. I heard they involve injecting directly into the scalp, so I'm curious if it's very painful and how many sessions are required. I'm also wondering if I should just consider it a treatment that provides nutrients to the scalp, or if it is a procedure that can actually help with hair growth. I am particularly concerned about the crown of my head; I want to know if scalp boosters are commonly used in this case, or if it is better to get a scalp diagnosis or blood test first to identify the cause. I've heard that temporary hair loss can be caused by stress or lack of sleep; would getting treatments be worthwhile in such cases? If anyone has personally tried Pantodil or a scalp booster, please share your honest experience regarding when you felt the effects, how many sessions you underwent, and what the pain or bruising was like!
