Phase Theory Beauty Co.™ grew from a simple question: what if hair care helped people understand their hair as well as care for it?
What began with Baby Hair® has evolved into a broader beauty-science platform connecting thoughtful formulation, ingredient transparency, hair and scalp education, research and products designed for real people in every phase of their hair journey.
Better hair care begins with better understanding.
The Beginning
Baby Hair® began in 2015 with a focus on caring for hair across textures, routines and generations.
Building the brand created something just as important as products: questions.
Questions about growth.
Questions about breakage.
Questions about scalp care.
Questions about ingredients.
Questions about what actually works — and why.
Those questions eventually became bigger than Baby Hair. They became Phase Theory.

Questions Create Curiosity
Curiosity Creates a Bigger Mission
Phase Theory Beauty Co.™
Products + Science + Education + Research

Founder & CEO
Dr. Bre Hayward founded Phase Theory Beauty Co.™ after years of building Baby Hair® and listening closely to the questions consumers asked about their hair.
Why does hair break even when it's growing?
What does the scalp actually need?
What do ingredients really do?
Which claims are supported by evidence — and which ones are simply repeated because they sound scientific?
Those questions became the foundation for something larger than a product company.
Phase Theory Beauty Co.™ was created to connect products with understanding — bringing formulation thinking, ingredient transparency, hair and scalp science, research and practical education into one ecosystem.
The Name
Hair moves through phases.
Growth.
Transition.
Rest.
Shedding.
Renewal.
But people move through phases too.
Childhood.
Changing routines.
Protective styles.
Damage and repair.
Growth goals.
New seasons.
New beginnings.
Phase Theory reflects our belief that hair care should meet people where they are — with products, information and understanding appropriate to the phase they're in.
We use science to ask better questions.
That means distinguishing established cosmetic function from emerging evidence, traditional use from clinical proof, and ingredient research from finished-formula performance.
We would rather explain what is known, acknowledge what is still being studied and update our understanding as better evidence becomes available than make science say more than it does.
Evidence before hype.
Today
Phase Theory has grown into an interconnected beauty-science and education ecosystem.
Formulation + Ingredients
Education
Learning Lab by Dr. Bre — Coming Soon
Phase Theory University now offers structured learning across Scalp Health, Hair Growth & Retention, Children's Hair, Ingredients & Formulation, Protective Styles & Hair Protection, Healthy Hair Habits and Beard & Facial Hair Science — because education became part of the company's mission, not an accessory to it.

Baby Hair® began with textured hair at its center, and that heritage remains part of who we are.
As Phase Theory grows, our commitment is broader: thoughtful products and credible education that recognize differences in texture, age, grooming practices, routines and needs without treating one kind of hair as the standard everyone else should fit.

"I didn't build Phase Theory because the beauty industry needed another product.
I built it because people deserve to understand the products they use, the hair they care for and the science behind the promises they're asked to believe.
We started with hair care.
We're building understanding."
