Our Top 5 Mascara For Straight Eyelashes Reviews – Expert Tested & Recommended
1. Maybelline Sky High Washable Mascara in Very Black – Volumizing, Lengthening, Curling, Buildable Formula for Dramatic Lashes
This is the mascara that took over social media for a reason. The Maybelline Sky High Mascara delivers dramatic length and volume without feeling heavy on your lashes. It is our top pick for straight eyelashes because the buildable formula actually holds a curl all day. If you have struggled with lashes that fall flat by noon, this one is a game changer.
Key Features That Stand Out
- ✓ Flex Tower Brush – The unique bending brush reaches every lash from root to tip for even coating
- ✓ Bamboo Extract Formula – Infused with bamboo fibers for lightweight length that does not weigh lashes down
- ✓ Buildable Volume – Layer it on for dramatic looks or keep it light for everyday wear
- ✓ Ophthalmologist Tested – Safe for sensitive eyes and contact lens wearers
- ✓ Washable Formula – Comes off easily with warm water and gentle cleanser
Why We Recommend It
This mascara consistently delivers sky-high length that lasts. During our testing, it held a curl on straight lashes for over 10 hours without dropping. The formula is lightweight enough that it does not clump, yet buildable enough for a bold night look. It strikes the perfect balance between length and volume, which is exactly what straight lashes need.
Best For
Anyone with straight or downward-pointing lashes who wants dramatic length and all-day curl hold. It is also great for those who prefer a washable formula over waterproof.
Pros and Cons
Pros:
- Exceptional lengthening effect that makes lashes look dramatically longer
- Holds curl on straight lashes all day without falling
- Lightweight formula that does not feel heavy or clumpy
- Easy to remove with regular makeup remover or warm water
Cons:
- Not waterproof, so it may smudge in very humid conditions or with watery eyes
- The brush can pick up too much product if you are not careful with application
Customer Reviews
Customer Review: “I have stubborn straight Asian lashes that never hold a curl. This mascara changed my life. My lashes actually stay up all day and look so long. I get compliments every time I wear it. The formula is light and never clumps. I have tried so many high-end mascaras and this drugstore one beats them all.”
Customer Review: “I was skeptical because of all the hype but this really works. My lashes touch my glasses with most mascaras but Sky High keeps them lifted. It builds nicely too. One coat for day, two or three for night. The only downside is it is not waterproof so I keep a different one for pool days.”
2. Maybelline Lash Sensational Sky High Mascara in Blackest Black – Volumizing, Lengthening, Curling, Buildable Formula, 1 Count
The Blackest Black version of the Maybelline Lash Sensational Sky High Mascara is our editor’s choice for a reason. It gives you the same incredible length and curl hold as the Very Black version but with an even deeper, richer pigment. If you want your straight lashes to look bold and defined, this shade delivers.
Key Features That Stand Out
- ✓ Blackest Black Shade – The deepest black pigment for maximum impact and definition
- ✓ Flex Tower Brush Technology – Bends and flexes to coat every lash evenly from root to tip
- ✓ Bamboo Fiber Infused – Lightweight fibers add length without weighing lashes down
- ✓ Buildable Formula – Go from natural to dramatic with just a few extra coats
- ✓ Contact Lens Safe – Ophthalmologist tested and approved for sensitive eyes
Why We Recommend It
This version stands out because the Blackest Black shade makes such a noticeable difference. Straight lashes often look sparse because they point downward. This mascara lifts them up and the deep black color makes them look fuller and more dramatic. During testing, the curl hold was just as impressive as the Very Black version, lasting well past the 10-hour mark.
Best For
Those who want the most dramatic, bold lash look possible. Perfect for anyone with straight lashes who wants maximum definition and depth of color.

Customer Review: “This is hands down the best drugstore mascara I have ever used. The brush is amazing and the formula is so smooth. My straight lashes actually look curled and long.

Complete Buying Guide for Mascara for Straight Eyelashes
Essential Factors We Consider
When choosing the best mascara for straight eyelashes, there are several key factors to keep in mind. First, look for a formula that is lightweight. Heavy mascaras weigh lashes down and cause them to droop faster. Second, the brush design matters a lot. Curved or slim brushes tend to grip straight lashes better and lift them upward. Third, consider whether you need waterproof or washable. Waterproof formulas generally hold curl better in humid conditions, but they can be harder to remove. Finally, look for ingredients like fibers or curl-locking polymers that help maintain the lift throughout the day.

The products on this list range from budget-friendly options like the KissMe Heroine Make at under $15 to mid-range picks like the Maybelline and L’Oreal options. Our top pick, the Maybelline Sky High, delivers luxury-level performance at a drugstore price. When planning your budget, consider how often you will use the product and whether you need waterproof protection. A good mascara should last about three months with daily use before it needs replacing.

Frequently Asked Questions
Q: What is the best mascara for straight eyelashes that will not smudge?
A: The KissMe Heroine Make Waterproof Mascara and the CLIO Kill Lash Superproof Mascara are both excellent choices for straight lashes that smudge easily. Their waterproof formulas resist humidity, sweat, and tears while keeping your lashes curled all day. If you live in a hot or humid climate, a waterproof formula is your best bet.
Q: How do I make mascara work better on straight lashes?
A: Start by using a good eyelash curler before applying mascara. Heat it slightly with a hair dryer for a few seconds for extra hold. Then apply mascara in a wiggling motion from root to tip. Let the first coat dry for a few seconds before applying a second coat. Choose a lightweight, buildable formula that will not weigh your lashes down.
Q: Is waterproof mascara better for straight eyelashes?
A: Waterproof mascara tends to hold curl better than washable formulas because it is designed to resist moisture and humidity. However, it can be harder to remove and may dry out your lashes over time. If you only need curl hold for special occasions, waterproof is great. For daily use, a high-quality washable formula like the Maybelline Sky High works beautifully.
Q: How often should I replace my mascara?
A: You should replace your mascara every three months. Mascara tubes can harbor bacteria over time, which can lead to eye infections. If your mascara starts to smell odd, change texture, or cause irritation, replace it immediately regardless of how long you have had it.
Q: Can I use a primer with mascara for straight lashes?
A: Yes, a lash primer can make a big difference for straight lashes. It creates a base coat that helps mascara grip better and last longer. Many people with straight lashes find that using a primer before mascara significantly improves curl hold and overall wear time.
We hope this guide helps you find the perfect mascara for straight eyelashes that works for your needs and budget.
