Bette Anne and Tim Duffy

Bette Anne and Tim Duffy are excited and proud to be founding franchise owners of Deka Lash. As a passionate “addict” of eyelash extensions herself for many years as National Champion and World-Ranked competitive ballroom dancer, Bette Anne knows that long, full lashes can make women feel beautiful and powerful. As one of the youngest women in advertising agency history to achieve critical success, she knows brands and how to build a business. Now retired from both ballroom and advertising, Bette Anne is thrilled to partner with her attorney husband, Tim, on her third career: owning and operating the first Deka Lash locations in Illinois. From their first encounter with Deka Lash, the Duffys were impressed with the quality of the corporate organization, the innovative studio design, the best-in-class Lash Artists, the proprietary products, and the unparalleled brand experience. They are looking forward to introducing Deka Lash to the North Shore of Chicago, and instilling inspiration and confidence to all women – customers and employees alike.

General FAQs

What are eyelash extensions?

Lightweight and made from a high-quality synthetic blend, eyelash extensions are either one singular lash or a fan of lashes, and are applied to your natural lashes to enhance the appearance of eyelash length, curl, and density.  Both types of lashes come in a variety of lengths, but fans also come in a variety of options.  A fan consists of multiple lashes that share the same base.  As with a singular lash extension, one fan is applied to one natural lash to create a rich and full lash line.

Most importantly, our eyelash extensions come in a wide variety of lengths, curls, and fans.  In other words, the customization options are endless when it comes to creating your perfect lash look.

What is TrueXpress?

TrueXpress is a new way of applying lashes to give you a fresh, naturally full look in half the time of a standard full-set appointment. Fuller yet lighter-looking than our Classic look, and less dramatic-looking than our TrueVolume look, TrueXpress is perfect for the person on-the-go who doesn’t want to sacrifice their lashes. 

The look is achieved through our innovative lashing technique, available only at Deka Lash, and was created with your busy schedule in mind.  

What is TrueVolume?

TrueVolume is made possible through our wide variety of multi-lash fan options.  By adding a multi-lash fan to each natural lash, TrueVolume adds as much fullness, length, and curl as you want – making it our most customizable service yet.
Perfect for anyone with naturally thin lashes, for anyone who already has naturally full lashes and is looking to add both density and length, and for anyone looking to create a high-drama look.
With its unique ability to be dressed up or dressed down, we'd argue that TrueVolume is perfect for everyone.

What is Classic?

Classic lash extensions add length and curl to your natural eyelashes.  Applied without using multi-lash fans, one Classic lash extension is applied to one natural lash to give a mascara look – without the mascara.
We recommend Classic lash extensions for anyone who is looking to add length without adding fullness.

How many extensions are applied in a full set?

Because extensions are placed on a single natural lash, your lash artist will be applying approximately 70%-80% coverage of your natural lashes during a Classic and a TrueVolume service.

How long does it take to apply a full set of eyelash extensions?

Duration varies depending upon which service you select.

What can I do to make my eyelash extensions last longer?

Use only Deka Lash products on your extensions. Arrive at your lash appointments eye make-up free. Talk to your Lash Artists about proper aftercare and homecare.

How often should I schedule my refill appointment?

Due to the shedding cycle of a natural lash, we lose three lashes per day, on average. To keep your lashes healthy and full-looking, we recommended coming back in for your refill every two weeks.  If you choose to wait longer than two weeks, please know that anther full set is required after three weeks.

Can I swim in eyelash extensions?

After any extension service, you will want to wait 24 hours before getting your extensions wet. After your extensions have set they are water-resistant.

Will eyelash extensions damage my natural eyelashes?

Eyelash extensions, when properly placed by trained professionals using the highest quality products, will not damage your natural eyelashes.  Our Lash Artists go through rigorous and comprehensive training to receive their Deka Lash certification.  This includes weeks of practical training, in addition to theory, and involves a model training period.  We also have continued and advanced training for all of our Lash Artists after they receive their certification.

If you notice your natural lashes fall out while having lash extensions, don't fret – your natural lashes have their own shedding cycle and it's completely normal.  Our extensions are applied so that when your natural lash falls out naturally, the extension will fall out with it.

Why should I choose Deka Lash?

Here at Deka Lash our Lash Artists are highly trained experts in eyelashes and stand behind our work. You will receive a top-quality experience while maintaining your natural lash health.
