SCALP HEALTH INSTITUTE
SCALP HEALTH INSTITUTE
ISHI trains beauty professionals to understand the scalp as the foundation of healthy hair — through science-based education built for the salon floor, not the laboratory.
For decades, hair care has been treated as a surface concern — product, style, technique. ISHI exists because the scalp deserves the same rigor: an independent field of professional knowledge, not an afterthought to hair.
I moved from Japan to the United States, bringing with me the discipline of Japanese Head Spa. As a stylist, I met many clients struggling with hair loss, dandruff, irritation, sensitivity, and other scalp concerns — and I wanted to actually help them.
I quickly realized that experience alone wasn't enough. I wanted a stronger scientific foundation, so I could guide clients based on knowledge rather than assumption. That led me to study trichology and continue my clinical education in the United States. But when I returned to the salon floor, I found a gap between scientific knowledge and practical, everyday application. ISHI exists to close that gap.
The Leaf. Biologically, hair is made of dead cells — it is a result, not a cause. You cannot fix a plant by polishing its leaves.
The Soil. It is a living organ — a mirror of your client's inner health, and the environment everything else grows from.
By optimizing the soil today, we protect a client's hair — and their confidence — for years to come.
A professional credential for beauty industry practitioners who want to bring structured, science-based scalp assessment into their existing work — without stepping outside their scope.
Three capabilities, built in sequence across the program.
The biological foundation — scalp structure, hair growth cycles, and how the two relate.
A trained eye for reading scalp conditions accurately and consistently, in Module 10.
Translating assessment into client guidance, care recommendations, and confident referral.
Each module builds on the last, bridging trichology and real-world scalp care one layer at a time.
