Straight lashes often need less mascara than expected: extra weight can flatten the curl you want. That counterintuitive detail makes the best mascaras for straight eyelashes a category worth comparing closely.
This roundup weighs how different formulas approach lift, definition, length, and wear, so you can see where each one fits. Keep reading for a clear side-by-side starting point.
Key Takeaways
- Choose a lightweight, curling formula if heavy mascara quickly pulls your lashes straight.
- Prioritize a waterproof or water-resistant formula when curl retention matters more than easy removal.
- Look for a slim or precision wand to reach short lashes and separate them before adding volume.
- Select a fiber formula for extra length, but check for clump-control claims if your lashes are fine.
- Consider washable mascara for everyday use and waterproof formulas for humidity, long days, or special events.

Maybelline Sky High Washable Mascara
For straight lashes, this is a strong everyday pick if you want length, definition, and adjustable volume in one tube. The buildable formula lets you add intensity gradually, while the Sky High design targets a visibly extended look.
Because it is washable, removal should be easier than with a waterproof formula. The tradeoff is less resistance to water, humidity, and rubbing, so it may not hold a curl as firmly as a waterproof option.

CLIO Kill Lash Long Curling Mascara
Choose this formula when your straight lashes quickly lose their shape. Its waterproof fiber formula is designed to lengthen, lift, and help maintain a long-curled finish.

L'Oréal Telescopic Lengthening Mascara
This is a sensible choice for a defined, extended lash look rather than dramatic fullness. The Telescopic name and lengthening formula make it especially appealing if you want straight lashes to appear longer and more separated.
Carbon Black adds stronger visual contrast, which can make fine lashes look more noticeable. The main limitation is its length-first focus, so you may want a separate volumizing formula for a fuller appearance.

- Size:0.27 fl oz
- Color:Carbon Black
- Count:1
- Additional Feature:Telescopic lash effect

RMS Beauty Straight Up Mascara
RMS Beauty’s option fits you if you want clean-positioned makeup with a fuller lash effect. Its peptide technology is paired with a formula that lengthens, lifts, and strengthens, making it a good match for lashes that need both volume and structure.
The smudge-free claim supports a polished look through the day. Still, the product is positioned around volumizing performance, so it may not provide the same rigid curl hold as a dedicated waterproof mascara.

L'Oréal Voluminous Curved Brush Mascara
A curved brush makes this a practical option if you want help creating a lifted appearance from naturally straight lashes. The Voluminous Original formula is aimed at a fuller black lash look, while the brush shape supports more upward-looking application.
Its main strengths are straightforward volume and a brush designed around curvature. The limitation is that the listing does not specify a waterproof formula, so curl longevity may vary in moisture or on oily lids.

Its vegan, cruelty-free, paraben-free, and oil-free positioning may appeal if ingredient and brand values matter to you. Since the listing does not identify it as waterproof, it may be less dependable for preserving a curl through moisture.

L'Oréal Extensionist Mascara
This formula suits you if straight lashes need a combined lengthening, volumizing, and curling approach. Its extension-style positioning aims to create a more elongated eye look without relying on actual lash extensions.
The washable blackest-black format is convenient for everyday makeup and gives strong color payoff. Its honest drawback is the washable base, which may not offer the same humidity resistance or curl retention as waterproof mascara.

- Additional Feature:Extension-style lash look
- Additional Feature:Volumizing effect

SHEGLAM Iron Curl Mascara
Straight-lash wearers who prioritize curl retention should look closely at this waterproof formula. Its Iron Curl positioning pairs with long-lasting lengthening, giving you a focused option for lashes that tend to point downward.
Water resistance can make a mascara more dependable through humidity and long workdays. The compromise is more involved removal, and waterproof formulas can feel less forgiving if you prefer a soft, flexible finish.

- Type:Waterproof mascara
- Formula:Lengthening
- Additional Feature:Designed for straight lashes
- Additional Feature:Iron Curl effect
- Additional Feature:Long-lasting formula

e.l.f. Lash 'N Roll Mascara
This is a good fit if you prefer lifted, separated lashes over a thick, heavily layered look. The curling formula is built around visible lift, while its long-lasting design supports a cleaner result during the day.
The vegan and cruelty-free formula adds appeal for values-led shoppers. Because the listing emphasizes curl and separation rather than waterproof wear, you may need another option for swimming, heavy humidity, or maximum curl lock.

- Count:1
- Additional Feature:Visibly lifted lashes

Choose this mascara if you have short or straight lashes that are easy to miss with a bulky brush. Its flexible elastomer wand is designed to reach smaller lashes while building extreme length and volume in layers.
The buildable, no-clump positioning gives you control over the final intensity. The limitation is that the listing does not claim waterproof wear, so curl hold may be less reliable in damp conditions.

- Color:Black, Extra Black
- Formula:Buildable
- Additional Feature:Extreme lengthening
- Additional Feature:Flexible wand
- Additional Feature:Vegan and cruelty free
Frequently Asked Questions
Should you curl straight eyelashes before or after mascara?
Curl your lashes before mascara, never after the formula has dried. Curling coated lashes can make them stick to the tool and may contribute to breakage. Use a clean curler and apply gentle, even pressure. A quick-setting formula will help preserve the shape you create.
Is waterproof mascara best for straight eyelashes?
Waterproof mascara is often the best choice for maximum curl hold, particularly in humid conditions or if your lashes quickly lose their shape. Its tradeoff is a more involved removal routine. If you prefer easier cleansing, choose a water-resistant formula and apply thin coats. It may provide enough hold for everyday wear without requiring an oil-based remover.
Why does my mascara make my curl fall?
A wet, heavy formula can weigh down straight lashes, especially if you apply several coats. Thick waxes and oversized brushes may add volume but reduce lift and separation. Try a lightweight lengthening mascara, wipe excess product from the wand, and focus the first coat near the roots. Avoid layering until the previous coat has partly set.
How can I prevent clumps on straight lashes?
Start with a clean wand and remove excess mascara on the tube opening before applying. A slim, firm brush can separate lashes more effectively than a large, heavily loaded brush. Apply one thin coat, then comb through while the formula is still slightly wet. Add a second coat only where you need extra length or definition.
What mascara is safest for sensitive eyes or contact lenses?
Look for formulas labeled ophthalmologist-tested, fragrance-free, and suitable for contact-lens wearers. Tubing mascaras can also be worth considering because they often remove with warm water and less rubbing. Stop using any product that causes redness, itching, or burning. Keep the wand clean, avoid sharing mascara, and replace old tubes promptly.
