Are there any good products for severe hair loss?

Right after giving birth, as you all probably know, my hair was just falling out in chunks. But lately, I've been losing so much hair that my daughter told me my head looks completely empty, which is a shock.

Of course, there is also the influence of my mother's genes.

My hair loss is really serious. I've tried everything—hair loss shampoo, hair pack, everything—but it hasn't really helped. My mom recommended brewer's yeast, so I tried that too, but it wasn't that great.

I want to keep the hair I have~

If anyone has seen results with hair loss management methods or functional products, I sincerely ask for your advice.
