Our collection was founded with the mission to develop a creative, high performance hair care line that runs parallel to fashion, science, art, music and industrial design creative cycles.

By combining nature’s greatest ingredients, forward-edge technology and innovation, we make your hair be what it should be — the ultimate look that defines new stylistic territories. We use the highest quality essential oils and extracts to repair damage, keep hair young, supple and color new. We gently cleanse with no harsh sulfates and we style with no stripping alcohols.

We exclude all ingredients potentially toxic to humans, rare vintage couture, and our dear environment; 100% Vegan, Sulfate & Sodium Chloride Free, Gluten Free, Bad Taste and Paraben Free formulas are never ever tested on any animal.

Our Liquid Complex Culture™ defines our products and ensures nothing less than a hair miracle. They draw upon water — the spring of health and eternal youth, and an advanced delivery system that takes beneficial botanical ingredients and creates tiny molecules from that material to infuse unique anti-aging, strengthening, color preserving and purifying “I can’t believe I fit in this dress” results.

Number 4™ Style Bureau™ collaborates with and supports talented hairstylists, artists, environmentalist, fashion designers, musicians, taste- makers, writers, landscapers and scientists to not only decide where Number 4 goes next but to actively improve the state of our planet — each season.

That’s what we believe in. That’s what we live for.

Butterfly Loft Salon

American Salon Magazine recently wrote: “David and Alexis Thurston are truly innovators – perhaps more accurately, trailblazers – as they rethink industry tradition across business models, education, marketing, and management.  They are in many ways turning parts of the traditional salon model on its head – in the best ways and with genuinely empowering intentions.”

David and Alexis Thurston are the founders of Butterfly Loft, a beauty company whose mission is to provide education, inspiration, and innovative solutions to beauty professionals.

Since 2010, their salon Butterfly Loft, has served as the anchor for their operational base of their company.  The salon is one of the few green-certified salons in the county, and was named, “World’s Eco-friendly Model Salon” by Wella.

In 2014 and 2015, David and Alexis expanded their operations, creating two new salons under their new brand Ubungalows, which enables stylists to work in luxury, private salon suites, but to also have incredible access to education, inspiration, and collaborative opportunities.   

In 2015, David and Alexis Thurston founded Butterfly Loft Academy, which is a hands-on education institution that teaches the latest color trends and techniques.  In 2015, they also created Butterfly Circus, a new educational format that brings together top educators to work together to provide a fast-paced, inspirational, and educational hair show.  Butterfly Loft Academy and Butterfly Circus events have quickly become high profile events that attract stylists from across North America.

Combined, Butterfly Loft and Ubungalows make up 10,000 square feet of salon space and are home to 85 full-time beauty professionals in Los Angeles.  However, due to the social media revolution, David and Alexis’ influence reaches far beyond the walls of their salons, and because of this, they’ve played a key role in the global proliferation of the newest color techniques and trends.  They’ve also used their platform to become a symbol of collaborative teamwork, to become advocates for gender equality in the beauty industry, and to raise money for diabetes research.

Before creating Butterfly Loft, David co-founded Level6, a salon-exclusive, nationally sold hair product line.  Alexis is an award-winning stylist, educator, and salon owner.
