Any home remedies/tips/ideas for my hair?

A little bit of background:

I have generally thick, long hair. I come from a family with a heavy amount of Irish ethnicity so it's not too surprising I have such thick hair and so much of it as well.

Anyways, it falls out EVERYWHERE. I have no balding issue or anything. But it's like I shed. When my boyfriend and I are all cuddled up it's so embarrassing when he has to pick long strands off of everything. Even out of our underwear!!!!

So I want to know if anybody experiences the same issue or if they have any tips for me to try like eating some type of food or applying something in particular to my hair. My ears are open to anything to help decrease the amount of my hair that falls out.
