Three different reasons for hair loss. Three different treatment strategies.
The Gaunitz Trichology Method separates hair loss into three primary reasons—genetics and DHT, nutrition, and inflammation. Each affects a different area of the hair-growth system, so each one must be identified and treated individually.
One person may have one, two, or all three reasons at the same time. They can overlap, but they should not be treated as if they are the same problem. Each requires its own assessment and targeted treatment plan.
Understand what each reason affects—and how treatment differs.
The visible pattern is only one part of the story. GTM separates the underlying reasons so the treatment plan can address each one individually.
Genetic and hormonal hair loss
Inherited follicle sensitivity—especially sensitivity to dihydrotestosterone (DHT)—can gradually shorten the growth phase and miniaturize susceptible follicles.
Often noticed at the temples, part, crown, or top of the scalp.
Nutritional hair loss
Hair growth depends on adequate energy, protein, vitamins, minerals, and healthy body reserves. A deficiency or major nutritional disruption may contribute to diffuse shedding.
Often appears as increased shedding or reduced density across the scalp.
Inflammatory hair loss
Inflammation involving the scalp, follicles, or immune system may disturb growth—and some inflammatory or scarring disorders require prompt medical evaluation.
May include itching, burning, redness, scale, tenderness, patches, or rapid change.
Separate the reasons. Treat each one individually.
Identify the hair-loss pattern
Document where the loss is occurring, how quickly it is changing, and whether scalp symptoms are present.
Determine which reasons apply
Assess genetics and DHT, nutritional status, and inflammation separately. Do not assume that one finding explains everything.
Treat each reason directly
Build a targeted treatment plan for every identified reason and coordinate medical care when diagnosis or prescription treatment is required.
Important: GTM is an organizational framework, not a diagnosis. Some forms of hair loss are temporary, some are progressive, and some can permanently damage follicles without timely medical care.
What does the hair loss look like?
Use these visual pathways to learn about common presentations. Appearance alone cannot confirm a condition.
Gradual pattern changes
Receding temples, widening part, or progressive crown thinning.
See androgenetic alopecia →Diffuse shedding
More hair in the shower or brush, with reduced density across the scalp.

A verified trichologist can document the visible pattern, review relevant contributors, and help coordinate an appropriate plan.
