Most mascara reviews test on lashes that are already curled, long, or naturally voluminous. This makes the reviews useless for the significant population of people with straight, downward-pointing lashes that refuse to hold a curl. If your lashes point south within an hour of using an eyelash curler, standard mascara recommendations will not help you.

The problem is formulation. Mascaras that are wet and heavy — and most volumizing mascaras are both — physically weigh down the curl. The water content softens the keratin in your lashes, allowing them to droop back to their natural position. For straight lashes, you need a formula that is dry, lightweight, and quick-setting.

After testing ten mascaras over four weeks on lashes that are notoriously resistant to curling, two clear winners emerged. The Kiss Me Heroine Make Long and Curl Mascara ($14) is a Japanese drugstore hero that has earned cult status for good reason. The quick-drying formula locks a curl in place for a full day without budging. It is not the most volumizing option, but for curl retention alone, it is unmatched.

The second standout is the Lancome L'Extreme Mascara ($28), which provides more volume than the Heroine Make while still maintaining respectable curl hold. It is the better choice if you want a balance of curl, length, and volume, though it does not match the Heroine Make on pure curl endurance.

For straight lashes, the mascara formula matters more than the wand. Wet, heavy formulas will always undo your curl. Go dry and fast-setting.

Curling Technique

No mascara can hold a curl on lashes that were not properly curled to begin with. Heat your eyelash curler with a hair dryer for three seconds (touch it to your wrist first to make sure it is not too hot). Curl at the base, middle, and tips in three separate squeezes. Apply mascara immediately after, while the keratin is still warm and pliable.

Waterproof formulas hold curls better than washable ones because they contain less water. If curl retention is your primary concern, always choose waterproof. Remove with an oil-based cleanser to avoid damaging the lashes.

The Verdict

Straight lashes are not a lost cause. The right formula, applied with the right technique, can create a curl that lasts all day. The Heroine Make is the budget champion; the Lancome is the luxury upgrade.

Our rating: 4.0 out of 5. Curl retention is a specific problem with specific solutions. These two deliver.
