Zone 1^TM

DHT Blocker Maximum Strength

Concentrated DHT Blocker Support

The First and Only Nutraceutical Brand Accepted by the American Hair Loss Association

Built around SEREVELLE™ — an advanced, clinically studied, pharmaceutical-grade saw palmetto extract known for its uniquely rich profile of bioactive free fatty acids — this formula provides robust, natural support for fuller-looking hair in a convenient once-daily single softgel. SEREVELLE™ is produced using a specialized refinement process that yields up to 75× more concentrated bioactive fatty acids than typical saw palmetto powders, offering a level of purity and consistency that sets it apart.

This next-generation extract anchors a multi-therapeutic blend of green tea extract, pumpkin seed oil, pygeum, and nettle root—ingredients traditionally used to help maintain healthy hormonal balance, support normal shedding rhythms, and promote a calm, nourished scalp environment. With added Vitamin D3 to reinforce healthy follicle signaling, the formula delivers comprehensive, long-term support for strong, resilient, healthier-looking hair—naturally.*

Before

After 90 days

“I had tried everything and given up when I found Advanced Trichology. At first I thought nothing was happening, but I stuck to the plan and my hair actually grew back!”

Before

After 180 days

“Hair loss is stressful, scary, and heartbreaking so I wanted to provide an early review so others, like myself, can have a bit of a sigh of relief. I’m happy with my experience.

“I was losing confidence along with my hair, but after a few months on the Advanced Trichology routine, I started seeing new growth. My before-and-after photos still surprise me.”

“My shedding slowed down first, then I noticed baby hairs coming in. It’s the first time in years I feel hopeful about my hair.”

“I used to avoid bright lighting because my scalp showed so much. Now my hair looks fuller and healthier, and friends keep asking what I changed.”

“I followed the plan exactly and the results were worth it. My hair feels stronger, my part looks smaller, and I finally see real regrowth.”

“I bought the products out of desperation, but they exceeded my expectations. My hair is thicker, my scalp feels better, and my confidence is up.”

“I could see my hair thinning in photos, which was heartbreaking. After sticking with Advanced Trichology for a few months, the change has been dramatic.”

“My stylist noticed the improvement before I did. She said my hair looked fuller and healthier — and now I can see the difference in every picture.”

“I wasn’t expecting fast results, but consistency really paid off. My hair is growing again, and my scalp isn’t irritated anymore.”

“The transformation has been incredible. I went from visible thinning to a fuller head of hair, and I’m more confident going out without hats.”

“I was skeptical because I’d tried so many things, but this is the first routine that made a visible difference. My hair looks fuller and feels healthier than it has in years.”

“I used to dread washing my hair because of how much I’d lose. Now the shedding has slowed down, and I’m actually seeing new growth in the spots that worried me the most.”

“I didn’t expect my before-and-after photos to look this different. My hair feels thicker, my part has filled in, and I finally feel like myself again.”

“My confidence took a hit when my hair started thinning, but sticking with the plan changed everything. My scalp isn’t showing anymore, and my hair looks strong and full.”

“I had patchy thinning around my temples, and now those areas are filling back in. It feels amazing to finally see progress.”

“My thinning was getting worse every month, and it really scared me. After staying consistent, I started seeing small improvements that turned into big ones.”

“I kept seeing progress month after month — less shedding, healthier strands, and now actual regrowth. I’m honestly thrilled with the results.”

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.
