You should be using a volume building mascara

To add drama to your eyes and thickness to your lashes, look for mascaras that have thicker formulas containing waxes, silicones, and/or collagen, which will work to coat each lash and give the appearance of thicker lashes.

Try these reader favorites:

L'Oreal Paris Extra Volume Hydra Collagen Plumping Mascara, $7.99

Bare Escentuals Buxom Lash Mascara, $18

If you have problems with mascara flaking off or if you have an oily scalp or face and you can never get mascara to stay on your lashes, opt for a waterproof formula like Dior Diorshow Black Out Waterproof Mascara, $24

And, remember to throw out your mascara after three months of use, says Hezekiah, adding that dried up formulas are prone to clumping.
