Trichology is the paramedical science that studies the structure, function and diseases of the human hair and scalp.

Trichology explained

It was born in London in 1902 and as well as treating hair and scalp related disorders, searches for the cause(s) behind the hair loss. A trichologist will focus on the process of naturally regrowing hair by analyzing the scalp and gaining a thorough client history


William Gaunitz WTS

Certified trichologist.

He has trained in London, France and Australia, as well as being the founder of the Evolution Hair loss Institute in Phoenix, Arizona.

He has been a pioneer of Laser Light Therapy for hair loss which he uses in conjunction with other treatments, and is the mastermind behind the most comprehensive multi-therapeutic complete system for hair growth available today.


Trichology Designed
to Deliver Results

The modern world has created the perfect environment for hair loss. With the increase of pharmaceutical usage, hormone replacement therapy, stress, poor diet, mineral deficiencies, and sedentary lifestyles, we are seeing more and more people dealing with this condition.

Stopping hair loss is not as easy and as simply applying a different product to your hair for a short period of time. It requires understanding and blocking the reasons that caused hair loss in the first place.

Most products or treatments on the market focus solely on one specific type of hair loss. But… our  unprecedented research and experience has taught us that multiple reasons for hair loss can manifest themselves at the same time. 

Thus to reverse hair loss and be successful at natural hair growth, you must use a complete multi-therapeutic trichological system that blocks all reasons for loss.

Developed over a 16 year period, our methodology has produced the most impressive results of any non-surgical hair loss treatment program. Within the Evolution Hair Loss Institute after working with thousands of clients, William Gaunitz WTS was able to refine a totally unique hair growth philosophy to create a system that is simple and easy to understand. This process is known as the Gaunitz Trichology Method (GTM).

GTM approved products are used in clinics all around the world to successfully treat multiple types of Alopecias. When used correctly, this multi-therapeutic system allows both men and women to typically regrow hair that has been lost in the previous 3 to 5 years in as little as 60 days.

Gaunitz Trichology Method in Action

If I hadn’t found William Gaunitz, I probably would be bald right now… I have more hair now than before the hair loss started! William figured out my hair loss after my first assessment.  I had previously seen two dermatologists with no solution.

William just really saved my hair. I am simply a happy person because of it! When my hair started falling out, I was devastated. For women our hair is our crowning glory. I was too young to lose my hair. When I found William, he spent the time to figure out what was going on… I am thrilled with my results and this really does work!

My hair was not growing back on its own after spending time in the hospital and being very sick. I had given it time to recover, but I knew it was time to do something more. I am very pleased with the results and with the staff. My hair hasn’t been this thick and full in years!
