Head Shape Matters
Hair Education by Kim Moore
Haircutting IS Mathematics. Understanding It Changes Everything.
Haircutting Doesn’t Just Involve Mathematics. It IS Mathematics.
Every haircut is the result of mathematical relationships between head shape, hair length, and geometry. Those relationships have always existed, whether we recognized them or not.
Head Shape Matters® is a patented haircutting methodology developed by Kim Moore that transforms these mathematical principles into a practical, measurable approach to haircut formulation.
Rather than relying solely on memorized techniques or visual estimation, HSM teaches hairstylists to harness mathematics to formulate haircuts with accuracy, precision, and confidence.
What If You Could Calculate a Haircut Before You Cut It?
Imagine knowing the exact angles needed to create a haircut shape before making the first cut.
Imagine knowing the exact length of hair at every level.
Imagine being able to calculate a precise haircut formula specifically for your client’s unique head shape, density, texture, and growth patterns.
With Head Shape Matters®, mathematics becomes a practical tool for haircut formulation.
Measure. Calculate. Cut.
A different way of approaching haircutting — because creativity can wax and wane, but math never lies.
A Little About ME
Dear Fellow Hairstylists,
In 2008, I had an eye-opening experience behind the chair.
Two clients came in back-to-back with the same photograph, requesting the same haircut. I gave them both the exact same cut, yet the results were completely different.
The difference? Their head shapes.
That experience changed the course of my career. I realized that if I wanted to truly master my craft, I needed to understand the mathematics behind haircutting on different head shapes.
What began as a question became years of research, experimentation, and discovery. I eventually returned to college to study mathematics, physics, and statistics, determined to find the answers I was looking for.
Today, Head Shape Matters® is a patented haircutting methodology that has evolved far beyond my original discovery. My continued research has led to new advancements in haircut formulation, making the mathematics more accessible and practical for hairstylists.
And now, I’m sharing that knowledge with hairstylists around the world.
Because I believe that creativity knows what it wants. Mathematics knows how to get there.
Sincerely,
