Shower hair loss significant

I’ve been on fin for about 6 months now, and haven’t really seen much positive difference. However I am noticing that when I run my hands through my hair I get less loose hairs out, although I also got a haircut recently. My question is, how many loose hairs do you generally get when doing these actions? I get around 20-25 in the shower overall, and between 0-3 when running my hands in my hair/ scratching my scalp.

The average person loses 100-150 hairs per day and a vigorous shower is a good place for a lot of it
