No, you cannot curl eyelash extensions. Eyelash extensions are made from synthetic PBT (Polybutylene Terephthalate) material that’s pre-set into a specific curl pattern during manufacturing. Unlike your natural lashes, these synthetic fibers don’t have the protein structure that allows for reshaping with mechanical curlers.
Curling them with traditional or heated tools can cause irreversible damage like breaking fibers, distorting their shape, and weakening the adhesive bond. This leads to premature shedding, uneven appearance, and reduced lifespan.
In this guide, we’ll dive into why curling eyelash extensions is a no-go and what happens if you try. Plus, we’ll explore safer alternatives to enhance your lash look without compromising the health of your extensions.
At Beauty Box, we know how to help you achieve the stunning lash look you desire without risking damage to your extensions or natural lashes.
Trust the experts: knowing what works (and what doesn’t) is the first step to keeping your lashes looking flawless. Let’s get started!
What Happens If You Try to Curl Eyelash Extensions?
Curling eyelash extensions can damage them, causing them to lose their shape and fall out prematurely. The heat from the curler can weaken the adhesive bond, leading to breakage and reducing the lifespan of the extensions.
Let’s dive into what really happens when you attempt to curl eyelash extensions. Trust me – it’s not worth the risk to your lashes or your wallet.
Immediate Damage Risks
Here’s what can happen the moment you try to curl your extensions:
- Breakage and Snapping: The synthetic PBT fibers become brittle under pressure from mechanical curlers, leading to immediate breakage. Unlike natural lashes that have some flexibility, extensions will snap rather than bend.
- Loss of Original Curl Pattern: Even if the extensions don’t break immediately, the pressure from curlers will distort their pre-set shape. Once this happens, there’s no going back – you’ll be left with awkward, misshapen lashes.
- Adhesive Bond Disruption: The physical force from curling can break the delicate adhesive bond between your natural lash and the extension. This leads to premature shedding and possible damage to your natural lashes.
- Heat Damage: Using heated curlers is even worse – the synthetic fibers can literally melt or become permanently deformed, creating a clumpy, unnatural appearance that can’t be fixed.
Impact on Extension Longevity
The reality is that trying to curl your extensions isn’t just ineffective – it’s a fast track to ruining your entire set. If you’re unhappy with your current curl pattern, book an appointment with your lash artist to discuss different options. They can recommend the right curl type to give you the look you want without compromising the integrity of your lashes.
Can You Use a Heated Eyelash Curler on Extensions?
The short answer is no – using a heated eyelash curler on extensions is a recipe for disaster.
Here’s why this seemingly innocent beauty tool can completely ruin your lash investment.
Types of Heated Curlers and Their Impact
Here’s what happens with different types of heated curlers:
| Curler Type | Heat Level | Impact on Extensions | Safety Rating |
| USB Heated Wand | 80-100°C | Immediate melting of PBT fibers | Extremely Unsafe |
| Battery-Powered Curler | 60-80°C | Warping and adhesive breakdown | High Risk |
| Heated Comb Style | 40-60°C | Gradual fiber deterioration | Still Unsafe |
| Mini Heated Curler | Variable | Uneven heat distribution causing patchy damage | Not Recommended |
Why Heated Curlers Are Never Safe for Extensions?
Heated curlers can damage eyelash extensions by weakening the adhesive bond, causing them to lose shape and fall out prematurely. The heat can also lead to breakage and reduce their lifespan.
Let me break this down for you:
- Heat + PBT = Disaster: Think of what happens when you hold a plastic bag too close to a heat source. That’s essentially what you’re doing to your extensions – they’re made of synthetic materials that can’t withstand heat.
- Adhesive Breakdown: Even if you’re super careful, the heat weakens the special adhesive that bonds the extension to your natural lash. Once this bond is compromised, your extensions will start falling out in clumps.
- Irreversible Damage: Unlike natural lashes that can recover from occasional heat styling, extensions are permanently altered by heat exposure. There’s no “fixing” melted or warped extensions.
What To Do Instead
If you’re not happy with your current curl pattern, here are your safe options:
- Book a Removal and Reapplication: Have your lash artist remove the current set and apply new extensions with a curlier pattern.
- Try a Different Curl Type: Consider switching to a more dramatic curl like D or DD curl for your next set.
- Layer Different Curls: Work with your lash artist to create a custom look using multiple curl patterns.
Remember, trying to alter your extensions with heat isn’t just ineffective – it’s a fast track to wasting the money you invested in your lash set. And trust me, replacing a damaged set of extensions costs way more than choosing the right curl pattern from the start.
Why Do Eyelash Extensions Lose Their Curl?
Let’s face it – nothing is more frustrating than watching your perfectly curled extensions start to droop. But there’s usually a clear reason why this happens, and better yet – ways to prevent it.
Environmental Factors
Here’s what’s really causing your extensions to lose their curl:
- Sleep Position: Side and stomach sleeping can literally crush your extensions against the pillow, gradually training them to point in different directions. This is one of the biggest culprits I see with my clients.
- Hot Showers: Prolonged exposure to hot water and steam can soften the PBT fibers. While they’ll eventually return to normal, repeated exposure weakens the curl over time.
- Heat Styling: Using hair dryers, curling irons, or doing your makeup under hot lights exposes your lashes to direct heat that can alter their structure.
- Improper Cleansing: Rubbing or tugging at your extensions while cleaning or using oil-based products that break down the adhesive bond.
- Product Buildup: Heavy mascaras, oil-based serums, or waterproof eye makeup can weigh down the extensions and affect their curl pattern.
Prevention Methods
Here’s your game plan for maintaining that perfect curl:
| Care Aspect | Do’s | Don’ts |
| Sleeping | Use silk pillowcase, sleep on back | Sleep face-down, use cotton pillowcases |
| Cleansing | Gentle brush with lash cleanser | Rub eyes, use oil-based removers |
| Product Use | Water-based, extension-safe products | Oil-based products, waterproof makeup |
| Daily Care | Gentle brushing with clean spoolie | Touching, pulling, or playing with lashes |
| Heat Exposure | Keep face away from heat sources | Direct steam, hot tools near eyes |
The key to maintaining your extension curl isn’t just about what you do – it’s about creating good habits. Think of your lash extensions like an investment. The better you care for them, the longer they’ll maintain that perfect curl you paid for.
And here’s a pro tip: If you notice your extensions starting to lose their curl, book a maintenance appointment with your lash artist sooner rather than later. They can assess whether it’s a care issue or if you might benefit from a different curl type for your next set.
What Are the Safe Alternatives to Curling Extensions?
Instead of risking damage by trying to curl your extensions, let’s look at professional solutions that actually work. After all, getting the right curl from the start is way better than trying to fix it later.
Professional Options Available
Here’s a comprehensive breakdown of your options:
| Curl Type | Lift Angle | Effect | Best For |
| J Curl | 30° | Natural, subtle lift | Straight natural lashes, hooded eyes |
| B Curl | 45° | Gentle uplift | Most eye shapes, natural look |
| C Curl | 60° | Open-eye effect | Universal favorite, medium drama |
| D Curl | 70° | Dramatic lift | Deep-set eyes, special occasions |
| L+ Curl | 90° | Maximum lift | Monolids, downward-pointing lashes |
| CC & DD | 65-75° | Extra volume | Glam looks, photo shoots |
Pro Tip: Consider a “curl mapping” service where your lash artist uses different curl patterns strategically across your eye to create a custom look. For example, using stronger curls on the outer corners for a cat-eye effect, or softer curls near the inner corners for a natural appearance.
If you’re not happy with your current curl pattern, book a consultation with Beauty Box. We can assess your eye shape and natural lash direction to recommend the perfect curl combination for your next set.
How Should You Care for Curled Eyelash Extensions?

Daily Care Routine
Here’s your step-by-step guide to maintaining those perfectly curled extensions:
- Morning Care:
- Wait until lashes are completely dry
- Gently brush through with a clean spoolie brush
- Work from base to tip with light, upward strokes
- Avoid pressing or pulling on the extensions
- Throughout the Day:
- Keep your hands away from your eyes

Frequently Asked Question
Question: How Long Do Eyelash Extension Curls Typically Last?
Answer: On average, a professional lash extension curl will maintain its shape for about 4-6 weeks. However, this depends on several factors like your natural lash growth cycle, lifestyle, and how well you care for them. Think of it like maintaining a blog – consistency is key.
Question: What Type of Pillowcase is Best for Maintaining Extension Curl?
Answer: Silk or satin pillowcases are your secret weapon. They create less friction compared to cotton, which means less wear and tear on your delicate lash extensions. It’s like choosing the right hosting platform for your blog – small details make a big difference.
Question: How Often Should You Clean Eyelash Extensions to Maintain Curl?
Answer: Clean your extensions gently 2-3 times per week using a specialized lash cleanser. Just like you wouldn’t neglect your blog’s maintenance, don’t skimp on lash hygiene. Use a soft brush and avoid rubbing or pulling.
Question: Is It Normal for Extensions to Lose Their Curl Over Time?
Answer: Yes, it’s completely normal. Just like a blog’s engagement can fluctuate, lash extension curls naturally relax. Environmental factors, your natural oils, and daily activities contribute to this gradual change.
Question: Can You Use Mascara on Curled Eyelash Extensions?
Generally, it’s not recommended. Mascara can break down the adhesive and compromise the curl. If you must, use a water-based, extension-friendly mascara sparingly. Think of it like guest posting – do it carefully and strategically.
