How to choose a lash tech whose work looks good and lasts

You've booked a lash tech based on a friend's recommendation, but when you scroll their Instagram grid, the photos look drastically different from each other—some wispy and natural, some dramatic and thick. You're wondering: which version actually represents their skill, and more importantly, which will still look good in four weeks?

Choosing a lash tech isn't just about finding someone with a portfolio. It's about identifying whether their technical ability matches what you want, and whether their work holds up over time. The difference between a tech who gets booked weeks in advance and one with perpetual availability often comes down to a few concrete signals.

Portfolio consistency tells you more than one stunning photo

Every lash tech has their best work. The question is whether that best work is a fluke or their baseline. Ask to see a minimum of 10 recent photos—ideally from different clients—taken in natural light. Look for consistency in lash distribution, symmetry, and how the extensions sit along the lash line. Work that varies wildly in quality suggests the tech performs well under ideal conditions but struggles with real clients or different eye shapes.

Don't just assess aesthetic appeal. Notice whether extensions are applied close to the skin (a sign of precision) and whether the bases are visible or hidden under the tech's own lashes. Hidden bases indicate careful, controlled placement. Visible gaps or uneven spacing can mean the tech rushes or hasn't refined their hand positioning yet. Also check whether their portfolio shows a range of looks—natural, medium, dramatic—rather than only one style. A tech who flexes across styles usually has better foundational control.

Retention and aftercare practices reveal real durability

Extensions that fall out after two weeks or look sparse after three are a waste of your money and time. When you contact a tech, ask directly: "What's the typical retention you see in your clients?" Their honest answer matters. Good lash techs report clients keeping extensions for 3 to 4 weeks before needing a fill, and they can explain why—usually a combination of proper application technique, suitable lash weight and length for your natural lashes, and realistic aftercare expectations.

Ask what aftercare routine they recommend and whether they send written instructions or a care sheet. Techs who invest in educating clients about avoiding oil-based products, not rubbing lashes, and gentle cleansing typically see better retention because clients aren't sabotaging the work. If a tech seems vague about aftercare or brushes it off, they may not be invested in your lashes lasting. Request photos of client lashes at the 2-week and 4-week marks if possible—this is the real test of longevity.

How they handle different eye shapes and lash types signals adaptability

Not every eye needs the same extension. A tech who applies the same length, curl, and weight to everyone regardless of natural lash strength, eye shape, or lift is prioritising aesthetics over health. During your consultation (in person or via photos), a skilled tech will assess your natural lashes and suggest what will genuinely work—sometimes that means slightly shorter than you wanted, or a lighter weight, because that's what your lashes can support without stress.

They should ask questions: Do you have a lot of natural lashes or sparse coverage? Are your lashes straight or already curly? Do you have hooded eyes or a lot of lid space? Do you sleep on your face? Their answers shape their application plan. Techs who skip this assessment and jump straight to your aesthetic preference often end up creating lashes that look good for two weeks then deteriorate rapidly or damage your natural lashes.

Responsiveness and professionalism during communication

Your first interaction with a tech—whether via WhatsApp, email, or phone—is diagnostic. Do they answer questions thoroughly or give one-word replies? Do they provide clear information about pricing, appointment length, and booking terms without making you chase them? Do they ask about your preferences and concerns, or do they seem impatient to move forward?

A tech who communicates clearly upfront usually applies the same precision to your lashes. They're organised, detail-oriented, and take the work seriously. They also tend to be honest if they think you're not a good fit—for instance, if your natural lashes are too weak for the look you want—rather than taking your money and delivering a compromised result.

When you're ready to book, platforms like Strove let you compare verified lash techs side by side, read client reviews that mention retention and longevity, and check their qualifications. That layer of vetting removes guesswork from the first phone call.
