Understanding The Science

This Product Targets Zone 1 Hair Loss^TM

Not sure if this product is right for you?

Take the Zone Hair Pull Test^™

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.

Zone 1^TM

DHT Hair Loss

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.

Zone 2^TM

Nutritional Hair Loss

Lack 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.

Zone 3^TM

Inflammatory Hair Loss

Scalp 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.
