Certified Trichologist

Trichology is a paramedical field and the scientific study of the hair, hair loss and associated scalp problems. This field is commonly referred to as the “bridge between cosmetology and dermatology.” It encompasses the study of diseases of the human hair and scalp, as well as the assessment of the cause(s) and treatment of these disorders.

This course is designed to provide students a greater depth of understanding of body chemistry, study of the anatomy & physiology, genetic influences, microscopy and nutrition and how it all relates to hair growth.

Our Certified Trichologist program allows students, seeking certification, to specialize in all things related to hair and scalp health. Trichologists take a holistic approach in assisting people with their hair and scalp problems, while examining the possibility of the contributing factors, such as, but not limited to:

  • Lifestyle
  • Symptoms/Signs
  • Diet/Nutrition
  • Mental Health/Wellbeing
  • Stress Factors
  • Physical Health
  • Medications
  • Environmental Influences  
  • And much more.…

Hair loss can be an early indicator of internal problems, such as:

  • Thyroid Problems
  • Cushing’s Syndrome
  • Anemia
  • Hormonal Imbalances
  • Mineral Deficiency
  • Lupus
  • Bariatric Weight Loss
  • And many more….

A Certified Trichologist may see clients complaining of sudden, excessive hair loss all over the scalp, bald patches which have suddenly appeared, or itching and excessive scaling of the scalp. You will learn how to carefully question each new client and examine the scalp thoroughly to assess the problem and its cause. A microscopic examination of the hair might be required to aid in the diagnosis and management of the problem.

The Certified Trichologist must then decide if treatment is necessary and whether the problem is within his or her scope of practice. There will be times when it is necessary to refer the client to a physician or other type of specialist.

The Certified Trichologist program teaches students how to manage both the medical and cosmetic side of the hair and scalp issues, while maintaining the integrity of both. The types of problems that a Certified Trichologist will encounter in their clinic can range from:

  • Maintaining general hair and scalp health
  • Chemical damage of the hair and scalp
  • Mechanical damage of the hair and scalp
  • Traction Alopecia
  • Scarring Alopecia
  • Alopecia Areata
  • Trichotillomania 
  • Scaly Scalp Problems
  • Psoriasis
  • And much more….

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 and scalp in health and disease. IAT was founded with the principal purpose of developing an educational course which would supply the necessary training to becoming a qualified trichologist.

IAT has been training students for 40 years. 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), India, Sao Paulo (Brazil), the U.S.A., Manchester (U.K.) and Riga (Latvia). Online lectures are also included. Medical doctors can undertake a shorter version of the trichology course.

Initially the trichology 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, Russia, Sweden, Argentina, Mongolia, Bangladesh, Mexico, Germany and the West Indies.

IAT is truly an international organization and they hold World Trichology conferences in many countries, which allows for great networking. The 2018 USA conference will be held in Washington, DC.
