There can be various reasons.
It can be a problem that needs to be treated, so you'd have to go to a physician.
As for me, I noticed a signifcant difference of hair loss when I just changed shampoos.
It can be something simple as you tying your hair in tight knots.
Or lack of minerals, protein, and iron, found in fish, poultry, cheese, and more. Or just a bad diet.
Don't worry, it's a really common issue. If you don't think anything's wrong, you can make your hair look thicker by using serums, volumizing shampoos, getting a body wave, etc.
