Barbara Spakowski

Vice President, Packaging Development

Responsible for: every aspect of the beautiful, custom packages you know and love us for.

What that entails, in her own words: Two of our biggest concerns are package compatibility and package functionality. Can the materials chosen for the packaging components stand up the product formulation maintaining product integrity and freshness? Does the method of dispensing the product from the package (lotion pump, flip top cap, aerosol valve) allow the product to be evacuated consistently from the first use to the last use. That’s why we do so much testing. Is the customer delighted every time she uses the pack?

CV highlights: Over 25 years (!) developing packaging innovations on a global stage.

The inspiration behind our bottles: No Frizz is meant to be reminiscent of a test tube—it’s a subtle and sophisticated nod to science. Full is a line for people who want bigger, fuller hair, so we created bottles that were round, full, and had a wide presence. Restore is meant to invoke health—it’s inspired by the shape of a milk bottle. Perfect hair Day packaging gives a nod toward Erlenmeyer flasks.

Michelle Brett

Senior Vice President, Sales

Hometown: Queens

Responsible for: Closing the deal and managing sales across retail, salons, and broadcast.

Why she works here: way back when (2008, before we even sold products) we gave her an unlabeled bottle of an early formulation to recruit her. She was hooked. At that point, the only way to get more product was to work here. She’s been at Living Proof ever since.
