Long, full lashes are more than just a beauty trend—they're a confidence boost. But what happens when your lash extensions start falling out too quickly, or your natural lashes seem thinner than usual? Even with extensions, your natural lashes need love. In fact, if you’ve been ignoring them, they may already be screaming for help.
Here are 5 clear signs your lashes are begging for a growth boost, and why a hypoallergenic, oil-free lash growth serum could be the game-changer your routine has been missing.
1. Your Extensions Aren’t Lasting as Long
If you’re noticing your extensions shedding after just 1 or 2 weeks, that’s not normal—it’s a cry for help from your natural lashes. Poor lash health means poor retention. Without a strong base, even the best lash tech can't make extensions stay put.
Why this matters: Natural lashes act as the foundation. Weak lashes = weak hold.
The fix: A lash serum without prostaglandin, like the one by Shigeru Beauty, supports natural lash strength and longevity—extending the life of your extensions while nourishing the lash line.
2. You See Gaps in Your Lash Line
Whether you wear mascara, extensions, or go bare-faced, random bald spots along your lash line are a red flag. Lash fallout can be due to stress, poor cleansing habits, or simply aging.
Why this matters: Gaps make extensions harder to apply and create uneven fullness.
The fix: Use a lash and brow growth serum daily to stimulate regrowth in sparse areas. Shigeru’s oil-free formula ensures it’s completely safe for lash extensions and won’t break down your adhesive.
3. Your Natural Lashes Feel Brittle or Break Easily
Do your lashes snap when you remove makeup or gently rub your eyes? Brittle, dehydrated lashes can’t support extensions and are more prone to damage.
Why this matters: Even high-end extensions will look sparse if the natural lashes beneath them are breaking.
The fix: A top-rated eyelash growth serum like Shigeru’s hydrates with nourishing botanicals—without harsh ingredients like prostaglandins that often cause irritation. It’s ideal for daily use, even for those with sensitive eyes.
4. You're Avoiding Lash Serums Because You Have Sensitive Eyes
So many lash lovers shy away from serums because they’ve had stinging, redness, or darkened eyelids from drugstore brands. We hear you.
Why this matters: Choosing the wrong serum can do more harm than good—especially for sensitive skin.
The fix: Shigeru’s eyelash serum for sensitive eyes is designed to be hypoallergenic, using clean, non-toxic ingredients that support lash health without side effects. You shouldn’t have to choose between beauty and comfort.
5. Your Brows Are Thinning Too
Let’s be honest—lashes and brows go hand in hand when it comes to framing your face. If both are looking sparse, it’s time to invest in a product that does double duty.
Why this matters: Brow thinning can sneak up on you, especially with age, overplucking, or stress. And ignoring it won’t make it go away.
The fix: Shigeru's lash and brow growth serum is designed to restore density where you need it most—whether that’s lashes, brows, or both. It’s oil-free, safe for use with lash extensions, and creates visible improvements in just a few weeks.
Final Thoughts: Don’t Wait Until It’s Too Late
Your lashes are speaking to you—and if they’re showing any of these 5 signs, it’s time to act. Healthy, thriving lashes don’t just happen overnight. But with the right serum, consistency, and care, you can transform your lash game for good.
