Real Results from Real People

After 4 months, my hairdresser mentioned that my hair changed and was stronger. He told me it had changed enough that I could change my hairstyle. Each hair had strengthened and thickened and was growing longer.

Zohar

I definitely am shedding less — my shirts used to be covered with my hair all of the time and now they aren't. I also have a whole new row of hair up front.

Alisa

I suffer from Alopecia. Instead of going a drastic route that cost me literally $4,000 at the Hair Club, I tested all brands of Biotin, then Keratin which was worse. Then Amazon introduced me to this product. That was indeed a great decision.

Dr. Linda Jenkins

Going through PANDEMIC STRESS, along with other family issues, I found myself actually seeing my hair fall out... in the drain, in the comb and brush, on our white floors. The Root Co. helped tremendously.

Diane

I'm an African American woman with relaxed hair. I'm getting older and my hair density isn't the same. My hair is getting thicker and it's growing.

Ivanete

For many years my hair would stop growing when it reached just past shoulder length. Since using The Root Co. my hair has suddenly grown several inches longer and everyone tells me how great it looks!

Common Questions

How long until I see results?

By Month 1: Shedding slows significantly. By Month 2: Baby hairs appear. By Month 3: 88% of clinical trial participants saw visible regrowth. By Month 4: Up to 2x increase in hair count. These are clinical averages from the independent 300-person study.
Why does this work when other supplements failed?

Other supplements target only 1 of 4 causes of hair loss. The Root Co. addresses DHT hormones, nutritional deficiencies, scalp inflammation, and stress damage simultaneously. US Patent #11,160,750 validates this four-cause mechanism.
Why is it biotin-free?

Biotin interferes with cardiac blood tests — a documented medical safety concern. The Root Co. uses targeted ingredients that address the actual biological causes of hair loss. Biotin-free is a safety advantage, not a gap.
How does this compare to Nutrafol?

Same 4-cause science — $240 less per year. Nutrafol requires 4 pills daily; we require 2. Nutrafol uses proprietary blends; we name every ingredient and amount. Their studies are company-funded; ours was independent, presented to the ISHRS. And we have a US patent.
Is it safe to take with my medications?

8 clean, fully disclosed ingredients with no known contraindications. Developed by a Harvard pharmacologist, reviewed by a board-certified physician. Vegan, non-GMO, GMP certified, FDA-registered facility. Consult your physician if taking medications or managing a medical condition.
What is the 90-day guarantee?

Full money-back guarantee within 90 days, no questions asked. Cancel your subscription anytime. We believe in the clinical data enough to guarantee your results.
How do I take it?

2 capsules per day — 1 in the morning, 1 in the evening. Each bottle contains 60 capsules (30-day supply). Take with food. Consistency is key: clinical results are based on daily use over 4-9 months.
Does it work for severe hair loss or alopecia?

The 300-person clinical study included participants with significant hair loss. The formula was designed for real hair loss, not wellness maintenance. For severe conditions including alopecia, consult your physician.
