Why Your Lash Lifts Look Crooked During Growout (It's Not Overprocessed)
Why Your Lash Lifts Look Crooked During Growout (It's Not Overprocessed) You just got a lash lift. For the first week, they look amazing—lifted, fluffy, exactly what you paid for. Then around week 4, you notice something: your lashes look a little wonky. Maybe they're bent at odd angles. The outer corners seem to point inward. Some look crispy or frizzy. Your first thought? "Did my lash artist mess up? Are my lashes overprocessed?" The answer is almost certainly no. What you're experiencing is called the awkward phase, and it's a completely normal part of lash lift growout. Once you understand what's happening, you'll see it's actually a sign that your lift was applied correctly. Let's break down what's really going on with your lashes—and why that crooked look doesn't mean damage. What the Awkward Phase Actually Is The awkward phase is a 4–9 week period where your lashes gradually shift shape as new, unlifted hair grows in from the root. During this time, the originally lifted portion of your lash moves upward along the hair shaft, creating bends and angles that look uneven or "crimped." Think of it like this: when your lash lift is applied, your lashes are curved at the base (closest to the lash line). That curve is tightest at the root where the hair is most moldable. As your natural lashes grow about 1/8 inch per week, the lifted portion slowly migrates away from the lash line, while fresh, straight hair pushes up from below. This creates a visible bend where the lifted and unlifted portions meet. Your upper lash line experiences this effect most noticeably because those lashes sit closest to the shield during the lift, which means they get the strongest curve at the base. The upper layer doesn't have lashes above it to support its shape, so it's naturally more prone to shifting during the grow-out phase. This is especially true if you sleep on your side or face—lashes are soft and moldable when you're resting, and consistent pressure can train them into new angles. Why It Looks Worse on One Side If your awkward phase is more pronounced on one side, look at where you sleep. Your lashes literally learn the position you rest them in night after night. If you favor sleeping on your left side, expect the left side of your upper lash line to show the most dramatic bending and wonkiness. The lashes get compressed under the pressure of your head and face, creating that slightly crooked appearance. Even if you sleep on your back most nights, occasional side-sleeping can create these patterns. And the outer corners are especially vulnerable because they have less support and more freedom to move. This is why aftercare matters so much during weeks 4–9. Consistently brushing your lashes back into place and avoiding sleeping positions that crush them can minimize how dramatic the awkward phase looks. What Overprocessing Actually Looks Like (And It's Different) Here's the critical distinction: overprocessing happens immediately, not weeks later. If your lash artist over-processed your lashes during the service, you'd know within the first 24 hours. Signs of actual overprocessing include: Lashes feel brittle or crispy to the touch (not just the appearance, but the actual texture) Breakage when you gently touch or brush them (hair snapping off, not bending or falling out naturally) Obvious gaps in your lash line (missing lashes, not just bent ones) Frizziness or frizzy texture throughout the lashes A burnt or chemical smell lingering after the service If you're in week 4 of your growout and your lashes look bent but feel normal, are intact, and don't break when you touch them? You do not have overprocessed lashes. You have the awkward phase. Those are two completely different things. An experienced lash artist can also tell the difference immediately. If overprocessing happened, it would show up right away—not weeks later during growout. And a good artist will adjust the curl strength or processing time on your next appointment if you mention concern about the growout phase, rather than blame you or dismiss your observations. How Sleep Position Affects Lash Lift Shape Your sleep position is one of the biggest factors in how dramatic your awkward phase becomes. Let's be specific about what happens: If you sleep on your side or on your face: The lashes on that side get compressed nightly. Over 8 hours, they're being pressed into a new shape. Your lashes are made of keratin, which is pliable—especially after a lash lift when the protein structure has been temporarily altered. That consistent pressure trains your lashes into a bend or curve that mirrors the position you're sleeping in. When you wake up, the bend stays there until it sheds out with new growth (usually 6–8 weeks). If you sleep on your back: You'll experience the awkward phase, but it's usually more even across both eyes and less dramatic overall. The solution? Protect your lashes while you sleep. Use a silk or satin pillowcase (it reduces friction and helps lashes keep their shape), sleep on your back when possible, or apply a nourishing coating—like vaseline, silk protein treatment, or lash serum—before bed to protect the lashes while they're compressed. How to Minimize the Awkward Phase You can't eliminate the awkward phase entirely—it's a natural part of growout—but you can make it less noticeable: Avoid sleeping on your lashes. Sleep on your back if possible. If you're a side sleeper, try using a face pillow that creates space for your lashes, or a silk eye mask that keeps lashes off your face. Brush your lashes daily. Use a clean lash spoolie to gently brush lashes back into the lifted direction. Do this in the morning and evening. The more consistently you do this, the more the lashes "remember" their shape and the less dramatic the bends look. Apply protective treatments. Use a lash lift aftercare serum, silk protein treatment, or even vaseline before bed. This protects the lashes and helps them stay nourished as they grow out. Healthy lashes are less prone to dramatic bending. Avoid eye makeup. The process of removing mascara, eyeliner, and eyeshadow add weight and friction to your lashes during the growout phase, which can exacerbate bending and shifting. Give your lashes a break or remove the eye makeup gently. Don't rub your eyes. This is self-explanatory but critical. Rubbing creates pressure and changes the shape of your lashes. If you're itchy, use a clean spoolie to gently comb through instead. Consider a softer curl on your next appointment. If your awkward phase was dramatic, mention it to your lash artist on your next visit. Ask for a softer or more subtle curl. Yes, this sacrifices some length, but the growout phase will look far more seamless. It's a legitimate trade-off, and a good artist will understand and adjust accordingly. When to Redo Your Lash Lift Most lash artists won't redo a lash lift during the awkward phase. The standard is to wait until approximately 80% of your natural lashes have grown out (usually around 8–10 weeks). This prevents over-processing and protects the health of your lash line. If you're at the 4–6 week mark and your lashes look wonky, it's almost always the awkward phase, not a failed service. Patience is your best tool here. The lashes that shed will be replaced with fresh, unlifted hair, and the overall look will smooth out naturally. The Bottom Line Your crooked or bent lashes during growout are a sign that your lift was applied correctly—strong enough to hold a visible curl as it migrates upward. Overprocessing would show up immediately with brittleness, breakage, or texture changes. What you're seeing is your lashes doing exactly what they're supposed to do during the natural regrowth cycle. Stay consistent with aftercare, protect your lashes while you sleep, and brush them back into place daily. The awkward phase is temporary, and understanding it helps you manage expectations and feel confident in your lash lift decision.

Learn moreIs Cysteamine Really Gentler Than Thioglycolate? What the Science Says
Is Cysteamine Really Gentler Than Thioglycolate? What the Science Says In the lash and brow industry, cysteamine-based lifting solutions are often marketed as a “gentler” alternative to thioglycolate. But does the science support this claim? The short answer: not really. While cysteamine is a newer reducing agent with some interesting properties, it has not been shown in published research to be gentler, safer, or more effective than thioglycolate. In fact, it performs differently — and not necessarily better. What Are the Differences? Both cysteamine and thioglycolate work by breaking disulfide bonds in keratin so the hair can be reshaped and “locked” into a new configuration during neutralization (Manuszak, 1993; Ghanem et al., 2025). However, the kinetics and effectiveness differ: Thioglycolate acts faster, reducing more disulfide bonds in the same time frame. Cysteamine reacts more slowly and less completely under identical conditions. Thioglycolate follows predictable pseudo-first-order kinetics; cysteamine can exhibit moving-boundary kinetics at lower pH, making it harder to control. Simply put, cysteamine breaks fewer bonds and may leave more hair unprocessed. That’s not necessarily “gentler” — it can also mean inconsistent results. Why Do Brands Call It Gentler? The perception that cysteamine is gentler seems to stem more from marketing than evidence. Because it acts slower and to a lesser degree, it might cause less visible damage if misused — but that hasn’t been demonstrated in controlled studies. Thioglycolate, on the other hand, has decades of research and proven safety when used properly (Manuszak, 1993, p. 79). This is why it remains the gold standard in professional hair, lash, and brow services. Regulatory Perspective: Banned in Japan It’s also worth noting that cysteamine is currently banned for use in cosmetics in Japan. While not uncommon for regulatory bodies to differ, this underscores that cysteamine’s safety and efficacy are not universally accepted. In contrast, thioglycolate continues to be approved and widely used worldwide — a testament to its long-standing track record. Why Professionals Still Trust Thioglycolate The bottom line: while cysteamine is a promising alternative worth studying further, current evidence does not support the claim that it is gentler or safer than thioglycolate. When applied by a trained professional and neutralized correctly, thioglycolate remains the most predictable, effective, and reliable option. References Ghanem, H., et al. (2025). Effects of thioglycolate compounds in an emerging technique in the world of cosmetics—brow lamination. Manuszak, M. A. (1993).

Learn moreIs Thioglycolate Safe in Lash Lifts? What the Research Really Says
Thioglycolate is one of the most trusted and widely used active ingredients in lash lifts, brow laminations, and hair perming — and for good reason. Research shows that thioglycolate works by predictably breaking and reforming disulfide bonds in keratin, allowing the hair to be reshaped safely and effectively. Decades of studies confirm thioglycolate’s excellent safety record when used properly, with minimal risk of long-term damage. It remains the gold standard in professional services thanks to its reliable performance and low allergenic potential. While overprocessing can lead to increased porosity and weakened hair, these risks are minimized under professional application and with proper aftercare. Compared to newer alternatives like cysteamine, thioglycolate is better studied, more predictable in its action, and backed by a much longer history of safe use. For clients and professionals alike, thioglycolate-based lash lifts remain a safe and effective choice when performed correctly.

Can you get your lashes wet after a lash lift?
Can I Get My Lashes Wet After a Lash Lift? If you've ever had a lash lift—or scrolled through TikToks of artists rinsing lashes right after the service—you might’ve had that moment of confusion: Wait... I thought you’re not supposed to get them wet? Let’s clear it up once and for all, based on real chemistry—not lash myths. TLDR: Yes, you can get your lashes wet. However, be careful not to mess up the direction of the lashes in the first 24-48 hours. While water is okay, avoid steam (saunas, hot yoga, hot showers) for up to 48 hours after the lash lift service. Why Do Some Artists Say “Don’t Get Them Wet for 24–48 Hours”? You’ll hear a lot of lash artists tell their clients to avoid water for an entire day (sometimes two). But I personally only ask clients to wait four hours—and here’s the reason why. It all comes down to understanding what actually changes the shape of the lash. Water Alone Doesn’t Break the Curl In the chemistry section of my course, I explain that a lash lift works by breaking and reforming disulfide bonds, which give lashes their natural shape. These can only be changed using chemical reducing agents like thioglycolate or cysteamine. Water doesn’t have the ability to break these bonds. However, it does affect hydrogen bonds—a secondary, temporary bond in the lash. When hair gets wet, hydrogen bonds soften, which is why you can style head hair differently when it’s damp. The same goes for lashes. So, in short: cool water touching the lashes after a lift won’t drop the curl. But that doesn’t mean anything goes right away... Why I Still Say “Wait Four Hours” While water won’t chemically reverse the lash lift, I still recommend avoiding it for the first four hours—not because of bond disruption, but because of lash styling. Right after the lift, lashes are still being set into place. The product used at the end of the service (often called a coating essence) helps lock in direction and shape. If water hits too soon, especially if lashes are touched or rubbed, it can shift the styling—not the curl itself, but how the lashes sit. Steam vs. Water: What’s the Real Concern? Here’s where things get more serious: steam. Steam is different from water because it combines moisture and heat, and that heat speeds up absorption. Let’s break this down: During a lash lift, the cuticle layer of the lash is opened so product can penetrate. After the treatment, the cuticle begins to close, but it takes up to 72 hours to return to its natural state. While the cuticle is still partially open, the lash is more porous, and anything that penetrates—like steam—can cause swelling. Swelling means too much water gets inside the lash, disrupting the setting process. This can weaken the curl or even cause the lash to feel brittle or over-processed. What Happens to the Lash Cuticle After a Lift? Here’s a breakdown of the lash’s porosity: Before lift: Cuticle is about 5–10% open During step one (reduction): Cuticle opens up to 40–60% After step two (neutralization): Cuticle drops to 20–30% 72 hours after lift: Cuticle returns to 10–15%, back to a healthy state The takeaway? The lash is most vulnerable right after the service, especially during that 72-hour reformation window. Why Steam Is More Damaging Than Water Steam isn’t just hot air—it’s water in vapor form that carries a lot more energy than liquid water. When that vapor hits the warm surface of a lash, it condenses back into liquid quickly and deeply penetrates the still-porous cuticle. This combination of sudden heat and moisture can: ✧Disrupt the lash’s structural reformation ✧Soften the shape before it fully sets ✧Cause premature weakening of the curl So while a cool face splash or shower after a few hours is totally fine, hot showers, saunas, and steamy facials should be avoided for at least 48–72 hours. In summary:You can get your lashes wet after a lift, just not right away—and it’s not about water ruining your curl. It’s about giving your lashes time to set, allowing the cuticle to close, and avoiding steam that could cause swelling. Stick to cool water, skip the steam, and your lift will last beautifully.

Why Hydration Matters After a Lash Lift (and Always)
Hydration is a critical part of lash lift aftercare. Just like skin, hair, and nails, lashes need moisture to stay flexible and healthy—especially after a chemical treatment. Dry lashes are brittle and more likely to break, while moisturized lashes can bend and withstand daily friction. Using a nourishing serum or Step 3 solution after a lash lift helps protect the hair structure, maintain your results, and prevent damage. Think of it as conditioner for your lashes: small effort, big difference.
