Hairloss over the years

I've always had a lot, and I mean a lot of hair, as you can see on the pictures where I'm a baby/kid. For more or less 3 years I've noticed that I started losing a lot of hair. And now I think I've lost at least half of my hair density since 2020. I've tried many things, like castor oil, beer yeast pills, hair gullies but nothing seems to work and it makes me very sad. I love my hair more than anything, I take good care of it. I oil it everyday with argan oil, sleep with a satin bonnet, wash it twice a week with silicone free shampoo. I desperately want to find my previous hair density. Do you have more tips?
