The International Association of Trichologists (IAT)
is a non-profit corporation founded in California in
1974 to promote the study, research and legitimate
practice in all aspects of the treatment and care of
the human hair a

nd scalp in health and disease. The trichology course was developed at the
University of Southern California during 1974-75
under the guidance of trichologist David Salinger. The course was designed as a home-study
(correspondence) course and, additionally, one
hundred hours of clinical training must be under-
taken under the supervision of an IAT-approved
trichologist. Students can presently undertake
clinical training in Sydney (Australia), Sao Paulo (Brazil), Manchester (U.K.), Mumbai or Chandigarh, India and Riga (Latvia). Initially the course was taught throughout North America
but, in 1979, Government colleges in Australia and
New Zealand contacted the IAT about introducing the trichology course. Teachers were trained and colleges in these countries began teaching the course in 1981. Since that time, IAT has trained students in several other countries including India, Singapore, China, South Africa,South Korea, U.K., Malaysia, Vietnam, Latvia, Nigeria, Kenya, Botswana, Brazil, Chile, Mauritius, Indonesia, Sri Lanka, Taiwan,Japan, Israel,
Mongolia, Bangladesh, Mexico
and the West Indies.

Trichology is the science of the structure, function and diseases of human hair.

It goes far beyond what we can see on the surface. Understanding the science behind hair and scalp disorders allows us to better recognise what may be happening, understand the factors involved and know when further investigation or medical referral may be required.

For allied health or hair professionals wanting to take their knowledge further, trichology can open an entirely new direction in their career.

Some legacies are inherited.
Others are built through a lifetime of dedication and then passed on.

For the Salinger family, trichology has been both.

Beginning with Ronald Salinger in the United Kingdom, carried forward by David and Sue, and continuing today through Chelcey's leadership of the International Association of Trichologists, generations of the Salinger family have devoted their lives to advancing the science, education and professionalism of trichology.

Over the past five decades, that commitment has grown into a global community of students, graduates and members across more than 94 countries—united by a shared passion for improving the lives of people experiencing hair and scalp disorders.

This photograph represents more than a family. It represents a legacy of knowledge, integrity and service that continues to shape the future of our profession.

Thank you, David, Sue and Chelcey, for your unwavering dedication to the International Association of Trichologists and to the global trichology community.

Please join us in recognising the dedication of the Salinger family and the incredible legacy they continue to build.
We'd love to see the comments filled with messages of appreciation from our global IAT family.

Researchers increasingly believe that successful hair loss management will rely on personalised medicine rather than a single approach for every patient.

This is an approach Trichologists have always taken!

Future care may combine:
• Clinical assessment
• Biomarkers
• Targeted therapies
• Lifestyle interventions
• Individual risk factors

As our understanding of hair biology continues to grow, personalised treatment strategies are likely to become increasingly important.
This is a view that trichologists have long supported.

This is more than "just dandruff."

For many people living with severe scalp psoriasis, the symptoms can be relentless.

Persistent itching. Burning. Pain. Tightness of the scalp. Thick scale that sheds onto clothing and bedding. Bleeding from scratching. Difficulty sleeping. Embarrassment and self-consciousness.

The constant worry that others will notice.

The physical symptoms are only part of the story. The emotional impact can be just as significant, affecting confidence, social interactions and overall quality of life.

Scalp psoriasis is a chronic, immune-mediated inflammatory condition that often presents with well-defined red plaques covered by thick, silvery-white scale. While it doesn't typically cause permanent hair loss, ongoing inflammation and scratching may contribute to temporary shedding.
Recognising scalp psoriasis early and understanding its impact allows practitioners to provide informed advice, appropriate referrals and compassionate care.

Behind every scalp condition is a person—and every person deserves to feel heard.

Hair loss is rarely "just hair loss."

Did you know that secondary syphilis can present with a distinctive form of hair loss known as syphilitic alopecia?

Often described as a "moth-eaten" pattern, this condition can sometimes be one of the first visible signs of systemic disease.
While relatively uncommon, it highlights why a thorough history, clinical examination and appropriate referral are essential in trichology.

As trichologists, recognising patterns—and knowing when to refer—is just as important as understanding hair itself.

Have you ever seen a case of syphilitic alopecia in clinical practice? Share your experience below, or tell us what trichology topic you'd like us to cover next.
