Through personalized Advanced Trichology treatments, thousands have achieved real hair growth—even after everything else failed.

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 90 days

“Everywhere I go people cannot believe how great that my hair looks and how much thicker that it's grown back because it fell out to literally you can see my scalp and I was so embarrassed.”

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.

Understanding The Science

This Product Targets Zone 1 Hair LossTM

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 1TM
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 2TM
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 3TM
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.

How to use

Step 1: Apply to wet hair and lather, ensuring complete scalp coverage. Let sit for 30 seconds to 1 minute, then rinse thoroughly.
Step 2: Apply a second application to wet hair and lather again. Gently massage the product into the scalp using your fingertips. Ensure thorough coverage of areas where you want to see hair regrowth. Leave on for 3-5 minutes, then rinse.
Note: Results may vary, and this product is intended to improve hair health and prevent hair loss.
