A Beginner's Guide to Eyelash Extensions

I never thought I’d be the kind of person who got eyelash extensions. My daily routine was pretty simple: some mascara (if I remembered), a little brow gel, and I was out the door. Honestly, lashes felt like too much effort for someone like me.

But then my best friend invited me to her wedding, and I wanted to look a little more polished without going overboard on makeup. I kept seeing photos of lash extensions online, so I booked an appointment, slightly skeptical and totally unsure of what to expect.

Obsession is an understatement.

I was hooked from the moment I saw my reflection. My eyes seemed brighter, more awake, and effortlessly glam. I felt like I’d just walked out of a photoshoot… every day.

If you have been thinking about getting lash extensions but do not know where to start, this eyelash extension guide is for you. Think of it as your go-to lash guide, whether you're thinking about getting eyelash extensions for the first time or you're a beginner lash tech learning the ropes. Let's dive into the ultimate lash extensions guide for rookies!

What are eyelash extensions?

Eyelash extensions are semi-permanent fibers that a trained technician applies to your natural lashes with a specially formulated adhesive. Unlike strip lashes or mascara, they’re designed to stay in place for several weeks, giving you fuller, longer lashes without daily effort.

They come in various lengths, thicknesses, and curls to create everything from a subtle upgrade to a bold, dramatic look. A skilled lash artist tailors the extensions to your specific eye shape, lash health, and personal style.

This eyelash guide would be incomplete without explaining their growing popularity, particularly among beginners. Extensions boost confidence, cut your beauty routine in half, and allow you to wake up looking flawless. Whether it is for a big event or everyday wear, this lash extension guide has you covered.

What are the benefits of having lash extensions?

Eyelash extensions have brought so many benefits to my routine, especially since I love looking polished without spending hours in front of the mirror. If you're anything like me, here's why you'll probably fall in love with them too:

• Instant volume and length. Get fuller, longer lashes with zero mascara.

• Time-saving. Simplify your beauty routine and wake up ready to go.

• Customizable looks. Choose anything from natural to dramatic depending on your eye shape and mood.

• Water-resistant. No smudging or running, even during workouts or vacations.

• Confidence boost. Highlight your eyes and feel more put together every day.

• Lifted curl effect. The right curl can open up your eyes, giving them a lifted, youthful appearance, similar to a mini non-surgical facelift!

• No need for daily lash products. Goodbye mascara, curlers, and strip lashes!
  
  

When I first discovered eyelash extensions, I had no idea how much they'd change my beauty routine. But honestly, the combination of beauty and convenience is a total game changer.

Are there any downsides to lash extensions?

While lash extensions are generally safe when applied by a certified, experienced technician, it is still important to be aware of the potential risks before scheduling your first appointment.

• Maintenance is key: To keep them looking good, you will need to infill them on a regular basis (usually every 2-3 weeks).

• Initial cost: High-quality lashes aren’t cheap, and the upkeep can add up over time.

• Proper care is a must: Skipping daily cleaning or brushing can cause premature shedding or irritation.

• Allergic reactions: Though rare, some people may react to the adhesive. If this is your first time, a patch test is always recommended to avoid allergic reactions.

Types of eyelash extensions

If you are new to lash extensions, the variety of lash extension types may seem overwhelming. Don’t worry, I’ve put together this beginner lash extension guide to help simplify it, so you can choose what works best for your style, lash health, and daily needs.

Classic lashes

Classic lashes are the go-to choice for beginners and those who prefer a more natural look. One extension is applied to each natural lash to add length and thickness without looking overdone. They’re ideal for enhancing your lashes subtly while still keeping a soft, effortless look.

Volume lashes

Volume lashes differ from classic lashes in the way they’re applied and the overall look they create. Volume lashes create a fuller, fluffier appearance by attaching lightweight fans, usually 2 to 6 ultra-thin extensions, to a single natural lash. This technique is perfect for clients with sparse lashes or those looking to add more drama. Despite their density, volume lashes still feel lightweight and appear soft, not heavy.

Hybrid lashes

Hybrid lashes combine the best of both worlds: classic and volume. This style blends individual extensions with small volume fans to create texture, depth, and a more dynamic look. Hybrids are my go-to when I want something fuller than classic but not as bold as full volume.

Mega volume lashes

Mega volume lashes take fullness to the next level by applying fans with up to 15 extremely fine lashes per natural lash. This results in the most dramatic, dense lash line possible. Perfect for photoshoots, big nights out, or if you're like me and just love a bold lash every day.

Flat or ellipse lashes

Flat lashes (also known as ellipse lashes) have a wider, flatter base that hugs the natural lash for better contact and retention. Despite having a darker, bolder appearance, they are lighter than traditional classics. Perfect for anyone who wants definition and fullness without compromising lash health or comfort.

Wet look lashes

Wet-look lashes are designed to mimic the effect of freshly applied mascara. They use narrow, closed-volume fans to create a smooth, textured lash line. I love how they add a glossy finish that’s dramatic but still sleek, which is great for trend-focused clients or editorial styles.

Kim K lashes

Inspired by Kim Kardashian's wispy, spiked lashes, Kim K lashes have uneven lash lengths and spikes strategically placed along the lash line. The result is a fluttery, textured finish with lots of dimension. It's an excellent choice for clients seeking a more glamorous, eye-catching look.

Russian volume lashes

Russian volume lashes use ultra-fine extensions (typically 0.05 or thinner) to create dense, fluffy fans that are applied to each natural lash. This technique provides impressive fullness without weighing down natural lashes, which makes them one of my favourite styles for a feathered, voluminous effect.

Choosing the right style for your eye shape

Not all lash styles are one-size-fits-all, and that’s where the magic of customization comes into play. I’ve found the best results happen when lash extensions complement your natural eye shape, lash line, and features. This part of the lash extensions guide walks you through the fundamentals so you (and your lash artist) can get it right from the start.

If you are unsure, your lash artist can help you by applying lash mapping techniques specific to your eyes and desired look. (For more information, see our lash mapping styles guide.)

To get started, here are some key factors to consider:

Eyelash extension length

Longer isn’t always better. I quickly learned that choosing extensions too long for your natural lashes can cause premature shedding and discomfort. A good rule is to go only 2–3 mm longer than your natural lash. If you have smaller eyes or wear glasses, slightly shorter lengths may look more appealing and feel more comfortable.

Eyelash extension volume

Volume refers to the number of lashes applied in a fan to each natural lash. For example, classic = 1:1, volume = 2D–6D, and mega volume = 6D–15D. When I want something bolder, volume gives that extra fullness. However, for everyday wear, I often stick with classic or hybrid for a softer vibe.

Eyelash extension curl type

Curl type plays a big role in how lifted and dramatic your lashes appear.

• J curls are very natural and subtle.

• B curls are slightly more lifted than J curls, perfect for clients who want a natural highlighting effect.

• C curls are ideal for a soft, eye-opening effect.

• CC curls are a slightly curlier version of C, adding a bit more drama without going full glam.

• D curls give a dramatic, curled look.

• L curls work well for hooded or downward-angled lashes.

• M curls have a lifted base and a dramatic flick, which creates an instant "eyelid lift" effect for monolids or deeply set eyes.

Just keep in mind: curl names can vary a bit between brands or suppliers, so it’s always a good idea to double-check when trying new lashes.

Choosing the right curl can either accentuate or soften your eye shape. For a more-in-depth look at styles, check out our lash extension styles guide.

What to expect during the lash appointment

I remember feeling a little nervous before my first lash extension appointment, but it turned out to be way more relaxing than I expected. The process begins with a brief consultation in which your lash technician evaluates your natural lashes and discusses the look you want to achieve.

Once you're lying comfortably with your eyes closed, the application begins. It usually takes between 1.5 to 3 hours, depending on the style and number of lashes applied. Honestly, It was so calming that I almost always fall asleep during mine now!

If the lashes are applied properly, you shouldn’t feel any pain or discomfort at all. Your lash artist will walk you through the aftercare instructions at the end, so you’ll know exactly how to keep them looking amazing for as long as possible.

How much are eyelash extensions?

Lash extension prices can vary depending on where you live, the experience of your lash technician, and the style you choose. On average, a full set of classic lashes costs between £60 and £100, while volume or mega volume sets cost £150 or more. Infills, which I usually get every 2 to 3 weeks, are more affordable than getting a full set each time.

While lash extensions are an investment, I’ve found that the time I save on daily makeup and the confidence boost make it well worth it.
