Experiencing hair loss and thinning hair

Hi. I'm experiencing hair loss since the time I got married (3 years) and my hair are gone extremely thin and alot of hair fall. I'm not pregnant yet, not taking any medication and I'm not even stressed out.

I tried alot of home remedies, in the salon the Matrix Biolage treatment in the parlor but nothing seems to work for me. I don't have this problem in my family as well. Please any suggestion?????
