The Origin Of The Discipline
Before AAHSD was established in 2018, there was no structured discipline connecting scalp patterns to the body’s internal burden.
No framework.
No methodology.
No standard.
We built the field.
We named the field.
We defined the work.
The American Academy of Hair & Scalp Diseases exists for professionals who require more than surface-level answers—and demand a level of education worthy of the clients they serve.
Where Hair And Health Converge
Hair loss is rising.
Client complexity is rising.
And traditional instruction stops at the scalp.
Functional Trichology™ goes deeper.
At AAHSD, you learn to understand how internal systems shape what you see on the scalp— using Physiology Mapping™ and the Triangle to Recovery™ to interpret the what, the why, and the how behind every case.
Hair Loss Is Health Loss™ isn’t a concept here.
It’s the foundation of the discipline.
This is not an extension of cosmetology.
This is the evolution of it.
THIS IS FUNCTIONAL TRICHOLOGY™
Built on the Triangle to Recovery™ and powered by Physiology Mapping™ and whole-body restoration.
Functional Trichology™ is the discipline AAHSD created to connect what appears on the scalp to the body’s internal burden.
It moves beyond topical theory and into clinical interpretation using two proprietary frameworks:
• The Triangle to Recovery™
– the structure that determines the what, the why, and the how behind every case
• Physiology Mapping™
– the process of reading patterns, systems, and internal strain through observable scalp changes
Functional Trichology™ restores the body first, knowing the hair will follow.
It is a whole-body, clinically informed discipline that redefines the way hair loss is understood and addressed.
THE INDUSTRY IS EVOLVING. WE ARE THE EVOLUTION.
Traditional trichology studies hair and scalp.
Functional Trichology™ studies the systems that shape them.
Where conventional training stops at symptoms,
AAHSD trains practitioners to interpret the internal burdens driving those symptoms— using clinical reasoning, structured methodology, and physiology-based assessment.
Most programs can teach what hair loss looks like.
We teach why it’s happening, where it originates, and how to correct it.
This is the shift defining the next era of hair and health.
And AAHSD is the institution leading it.
