The fibers tend to look a lot like actual lashes as they come off. But don't panic, it's not actually damaging or removing any of your natural lashes.

PROS: Thrive's will not smudge or flake on you even if you splash around near water. CONS: Thrive's can feel hard/crunchy and may feel strange to remove chunks off your lashes.

The tubing formula allows the mascara to stay put all day, until you apply some very light pressure with warm water to remove it (more on that later). I first tried the Thrive mascara last November.

Thrive Causemetics Review Summary While I have purchased some products that weren't the best for me, I do find overall that Thrive Causemetics are high-quality products in high-quality packaging and worth their pricepoints.

If you wear mascara and your eyelashes fall out excessively, you may be allergic to the product. Or you may be applying the mascara too roughly. Excessive eyelash loss can also be a sign of an underlying medical condition.

"Mascara can cause your lashes to fall out due to clogging the hair shaft," explains Phillips. "The hair shaft needs to be clean and filled with nutrients to stop it from getting dry or becoming clogged with excessive oil."
