In the world of beauty, few trends have redefined eye aesthetics like lash extensions. But beyond the glamour lies a mix of science, skill, and product chemistry that every lash artist should understand. Whether you’re a beginner or an experienced professional, knowing key lash extension facts can help you perfect your technique and elevate your client’s experience.
At Posh Deluxe, knowledge is just as important as quality tools. Let’s uncover the truths behind lash extensions — from how they work to what really affects their retention.
1. Lash Extensions Don’t Damage Natural Lashes — When Applied Correctly
One of the most common myths in the industry is that lash extensions ruin your natural lashes. The truth? Properly applied extensions cause no harm at all.
The key lies in isolation and weight selection. Using lashes that are too heavy or applying multiple extensions to one natural lash can cause breakage. With the right Posh Deluxe isolation tweezers and lightweight lash fans, you can ensure that each natural lash grows and sheds healthily underneath the extensions.
2. Adhesive Curing Depends on Humidity and Temperature
Lash adhesive isn’t a one-size-fits-all product — it’s a formula that reacts to your environment. A common lash extension fact many beginners overlook is that humidity and temperature directly affect curing speed and retention.
For example:
-
Too low humidity = slow curing, poor attachment.
-
Too high humidity = shock curing and brittle bonds.
Always work with a hygrometer and pair your adhesive with the right booster or sealer, such as Posh Deluxe Wrap Perfecto, to optimise performance and retention.
3. Priming Natural Lashes Improves Adhesion
Natural lashes naturally accumulate oil, residue, and dead skin cells — all of which can weaken adhesive bonds. That’s why cleansing and priming are non-negotiable.
A great example is the Posh Deluxe Lash Shampoo, designed for professional use to gently clean natural lashes before application. It removes sebum and debris, ensuring your adhesive bonds to a clean, oil-free surface for longer-lasting extensions.
4. Lash Extension Styles Are About More Than Just Looks
From Classic to Mega Volume, every lash style follows a specific mapping technique that enhances different eye shapes. But beyond aesthetics, lash mapping also affects weight distribution and retention.
Understanding styles like Cat Eye, Doll Eye, or Squirrel ensures you create balanced, comfortable sets that maintain lash health. If you’re just starting out, check out our blog on Lash Mapping 101 — a step-by-step guide using Posh Deluxe lashes for custom, professional looks.
5. Not All Lash Extensions Are Created Equal
One of the most essential lash extension facts is that the quality of your materials directly impacts your results. Cheap synthetic lashes often have uneven curls, stiffness, or poor pigment retention.
At Posh Deluxe, our premium lashes are crafted with precision and tested for consistent curl, softness, and durability — ensuring you get salon-quality results with every set.
6. Proper Aftercare Makes or Breaks Retention
Even the best application won’t last if aftercare is ignored. Educate your clients on how to look after their lash extensions:
-
Avoid oil-based products near the eyes.
-
Brush lashes daily with a clean spoolie.
-
Wash regularly with lash-safe cleansers.
Recommending Posh Deluxe aftercare kits helps your clients maintain retention while keeping their natural lashes healthy and strong.
7. Lash Artists Are Scientists, Too
Behind every beautiful lash set is chemistry, precision, and artistry. Understanding your tools — from adhesive composition to tweezer tension — transforms your craft from routine work into expert artistry.
