Male Hair Loss
Most men’s hair loss begins in Zone 1—the hormonal zone, where elevated DHT levels shrink hair follicles at the crown, mid-scalp, and temples. This type of genetic hair loss often starts in your 20s or 30s and worsens over time if not addressed. But hormones aren’t the only factor. Zone 2—nutritional hair loss—is also common, especially when levels of key nutrients like zinc, iron, and vitamin D3 are below optimal. Then there’s Zone 3—inflammatory hair loss. Often overlooked, this type of hair loss can be triggered by immune imbalances, stress, or scalp conditions that disrupt the growth cycle and contribute to shedding. At Advanced Trichology, we don’t just treat symptoms. We identify and target the underlying causes using the Zone Hair Pull Test™—a proven system for delivering real, lasting results.
Understanding The Science
Hair loss isn’t random—it follows a pattern.
At Advanced Trichology, we’ve identified three scientifically validated root causes of hair thinning:
hormonal (DHT), nutritional deficiencies, and inflammation. These underlying causes show up in predictable
zones on the scalp, allowing us to pinpoint the true source of your hair loss—and treat it with precision.
When testosterone is converted into DHT (dihydrotestosterone), it can shrink follicles and shorten the hair growth cycle. This hormonal imbalance is most often seen at the temples and crown—and is the leading cause of hair loss in both men and women. Our DHT-focused solutions help block this conversion and protect follicles over time.

Evans, Nguyen, Fernande, 2024Lack of essential vitamins and minerals like iron, D3, and biotin can silently starve hair follicles—leading to excessive shedding and slow regrowth. Nutritional deficiencies are often reflected in thinning along the sides and back of the scalp. Our targeted nutraceuticals are designed to restore these critical nutrients at clinical strength.

Evans, Nguyen, Fernande, 2024Scalp imbalance can disrupt healthy hair growth at the root. When the scalp becomes irritated—due to stress, immune changes, or product buildup—it can reduce blood flow and compromise follicle health, leading to shedding or thinning. At Advanced Trichology, we address this using a combination of calming botanicals, probiotics, and targeted nutrients that help support your body’s natural inflammatory and immune responses—both topically and internally—to promote a healthier scalp environment.
