CERTIFIED SCALP HEALTH SPECIALIST · CSHS

Bridging Trichology and Scalp Wellness.

ISHI trains beauty professionals, product specialists, and anyone passionate about scalp health to understand the scalp as the foundation of healthy hair — through science-based education built for the salon floor, not the laboratory.

01 — ABOUT ISHI

Scalp health, treated as its own field.

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.

  • Why scalp health, specifically Hair condition is a downstream result. The scalp — its balance, its barrier, its follicular environment — is the variable that actually determines long-term hair health.
  • Where trichology meets the salon ISHI connects trichology, hair science, and scalp wellness into a single practical framework — built to be used at the chair, not just in a textbook.

Certified Trichologist · Founder of ISHI

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.

ISHI PHILOSOPHY

Heal the Soil, Protect the Future.

HAIR

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.

SCALP

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.

02 — THE CREDENTIAL

CSHS Certification

CSHS Certified Scalp Health Specialist

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.

  • —Not a medical certification, and does not license the holder to diagnose or treat medical conditions.
  • —A professional-education credential recognized within the beauty and wellness industry.
  • —Focused on informed observation, client guidance, and knowing when to refer out.
  • —More structured and science-grounded than a typical head spa certification — but scoped to salon practice, not clinical trichology.

Doctors

Diagnose and treat medical disease — pathology.

Traditional Professionals

Focus on external appearance and temporary relaxation.

You — The CSHS

Assess visible scalp conditions, guide clients toward appropriate care, and recognize when to refer to a physician or dermatologist.

Superficial beauty wins a client for a single visit. Foundational care wins a lifetime of trust.

07 — SCOPE OF PRACTICE

Where a CSHS's judgment applies

The full working protocol is a course resource. Here is the overview that underlies the credential's trustworthiness.

Green

  • Assess and advise on common, non-medical scalp conditions
  • Recommend at-home and in-salon care routines
  • Educate clients on prevention and maintenance

Yellow

  • Monitor conditions that may need closer observation over time
  • Flag ambiguous presentations for further attention
  • Adjust guidance as a condition evolves

Red

  • Diagnose any medical condition
  • Treat conditions requiring dermatological or medical care
  • Delay referring a client whose presentation warrants one
08 — EDUCATIONAL DISCLAIMER

What CSHS does not license

  • —CSHS is an educational credential, not a medical license. It does not qualify the holder to diagnose, treat, or prescribe for any medical condition.
  • —CSHS is a knowledge credential, not a service license. What you're permitted to actually perform on a client — even shampooing, in states like California — still depends on your own cosmetology, barbering, or esthetics license (if any) and local regulations. Without such a license, the CSHS supports education and product guidance, not hands-on services.
  • —Any condition outside the Green/Yellow scope should be referred to a physician or dermatologist, not treated in-salon.
09 — CERTIFICATION REQUIREMENTS

Frequently asked questions

About the program

What is the CSHS?+
The Certified Scalp Health Specialist (CSHS) is an online certification from ISHI Scalp Health Institute. It teaches the science of the scalp and hair, how to recognize what you see, how to support clients within your scope, and when to recommend a medical evaluation.

Most students are hair stylists, barbers, estheticians, head spa professionals, and salon owners, but the program is also a good fit for people who sell or recommend scalp care products, and anyone passionate about scalp health. No license is required to enroll. Keep in mind that the CSHS does not license hands-on services: what you may do on a client still depends on your own license and local rules.
Is the CSHS a license or a medical certification?+

Will I become a trichologist?+
