Frequently Asked Questions

Premium Hair Complex is a physician-formulated hair growth supplement designed to target the root causes of thinning hair and support visibly thicker, fuller, and stronger hair. It uses a clinically proven, science-backed formula with standardized ingredients to address key internal triggers — including hormones, stress, lifestyle, metabolism, nutrition, and aging.
-
Premium Hair Complex targets six key root causes of hair thinning from within. By supporting hormonal balance, reducing stress-related shedding, optimizing metabolism, improving nutrition, and combating age-related hair weakening, it helps restore a healthy hair growth cycle. The result: visibly improved hair volume, coverage, and strength.
-
Premium Hair Complex is one of the most advanced and comprehensive formulas available. It is so complete that it could not fit into a single capsule, which is why it comes in two bottles (Part 1 and Part 2). Physician-formulated and clinically proven, it uses standardized, science-backed ingredients to deliver targeted, superior results — unlike generic hair vitamins or simple biotin-based products.
-
Our formula is so advanced and comprehensive that it requires two different capsules to deliver the full range of active ingredients effectively. You take 2 capsules from Part 1 and 2 capsules from Part 2 each day to ensure maximum impact.
-
Take 4 capsules daily — 2 capsules from Part 1 and 2 capsules from Part 2. For best results, take them together with food. This simple routine seamlessly fits into your daily wellness habits and ensures optimal absorption.

It targets the internal root causes of thinning that affect everyone, including hormonal changes, stress, metabolism, nutrition, lifestyle, and aging.

This leads to increased shedding, thinning, and reduced volume. Premium Hair Complex is designed to help balance these hormonal changes and support healthy hair growth.
-
No. Facial and body hair growth are triggered by different hormonal and local factors than scalp hair. Premium Hair Complex is formulated to support scalp hair follicles specifically and will not stimulate hair growth elsewhere.
