about

Extensia by April

April is devoted to creating elevated beauty experiences that empower women to feel confident, refined, and effortlessly radiant. With over 25 years of expertise in Goldwell hair color and premium hair extension services in Green Bay, (and now Coleman, Wisconsin) she approaches each client with intention, artistry, and uncompromising attention to detail. 

April is a Certified Great Lengths Hair Extension Specialist and the owner of Great Lengths Platinum Salon- Extensia. She is also a Goldwell Master Colorist, these distinctions reflect her mastery and commitment to the highest standards in the industry.

Her influence extends well beyond the salon. For several years, April traveled throughout the Midwest as a Goldwell hair color educator, collaborating with top professionals. She continues to stay at the forefront of emerging trends and techniques. This continual immersion in education and trend movement allows her to design modern, sophisticated looks that are meticulously tailored to each client. With a discerning eye for balance and harmony, April enhances natural beauty while subtly diffusing less desirable elements—delivering results that feel timeless, luxurious, and unmistakably personal.

Extensia’s Signature Philosophy

April believes true luxury is never rushed and never mass-produced—it is cultivated with care, intention, and respect for natural beauty. Much like the rhythms of nature she so deeply admires, her work honors balance, patience, and thoughtful design. Every color placement, every extension application, and every finished detail is approached as a custom creation, never replicated and never compromised.

In her private boutique setting, April offers an intimate, elevated experience where clients are seen, heard, and artfully enhanced. Drawing inspiration from organic textures, natural movement, and the effortless elegance found in the world around us, she creates hair that feels lived-in yet refined—polished without being overdone. The result is beauty that grows gracefully, moves naturally, and feels authentically aligned with each woman who wears it.

For April, hair is not simply a service—it is a craft, a collaboration, and a quiet luxury designed to restore confidence and celebrate individuality.

I work closely with you to create a look that will enhance your own natural beauty. My favorite part of each session is when your service is complete and you see the final outcome. You see yourself in a way you never thought possible, you immediately light up and it is then that I can literally see the increase in your self-confidence, it is then that my job is complete.

Often extensions are perceived as a way to give you longer and fuller hair in an eye-catching way. However, there are many ways that extensions can be used to accentuate your hair. Women who prefer a minimalistic and natural look can choose extensions too, as they can be truly subtle, extremely believable, and completely undetectable in the natural hair.

It's not so much about
changing who you are

as it is about enhancing what you have. Extensions are a flexible beauty tool that can help you get the dream look you’ve always wanted, whether that is a natural result, or a bold and dramatic change. As an added benefit, hair extensions simplify your morning routine.

Extension enhanced hair holds a blowout for days and creates a well-made-up appearance. You wake up ready to go!

Will hair extensions damage my hair?
You can be assured that Great Lengths’ Pre-Bonded and Tapes have been scientifically proven not to cause damage to healthy hair when applied correctly and maintained properly. The key to a successful, damage free application lies in the details of the application. There is no “cookie-cutter”, “one size fits all” application technique, as each client has different hair conditions and desired results that must be considered. The skill level of the stylist is crucial for a damage-free application and this is why Great Lengths Certified Stylists are the most sought after by extension clients worldwide.

How can I best care for my hair extensions?
April will provide you with detailed instructions at the end of your service. In general, less is more when caring for your new hair extensions. Be gentle with your hair when brushing and avoid shampooing for 48 hours after your service to give the bonds time to settle. We recommend using the Great Lengths natural boar bristle brush and separating your hair into sections when brushing. Tie your hair back loosely into a ponytail when sleeping to avoid tangles. Use recommended Great Lengths shampoo that does not contain sulfur, silk, or harsh chemicals. Wash gently and tip your head backward to rinse. Use conditioner only from mid-strand to the ends; avoid the scalp area and the bonds.
