Does Lustriva Work for Hair Growth? What Clinical Studies Show

Why Most People Struggling With Hair Thinning Never See Results

Hair thinning affects millions of women and can be caused by any number of factors, including stress, menopause, genetics, or nutritional gaps. Yet most people who try to address it never actually see a meaningful difference. They cycle through shampoos, serums, and supplements, spending hundreds of dollars with little to show for it. The problem usually isn't effort. It's information.

The supplement aisle is especially confusing. Products promise thicker, fuller, healthier hair, but few explain what their ingredients actually do, whether the doses are meaningful, or whether any real science backs up the claims. The result? Most people end up reaching for products built around one or two popular nutrients — usually biotin — without knowing that standard biotin may not be as effective as it sounds.

Biotin has been marketed as a hair growth staple for decades. But the research behind standard biotin supplementation for healthy individuals with no deficiency is surprisingly thin. That's where a newer, patented ingredient called Lustriva® changes the conversation.

What Is Lustriva?

Lustriva is a patented ingredient complex developed by Nutrition21, a science-driven ingredient company known for their clinically studied nutritional compounds. It combines two key components:

• Inositol-stabilized Arginine Silicate

• Magnesium Biotinate (a superior, highly soluble form of biotin)

Together, these two components form a complex designed to deliver biotin and silicon to the body more effectively than standard biotin supplements. 

This is meaningfully different from the basic biotin found in most hair supplements. Standard biotin (also called D-biotin or free biotin) has known effectiveness limitations, particularly at the high doses commonly used in hair supplements. Lustriva's Magnesium Biotinate form was designed to address those limitations.

Here’s What the Science Says

The clinical study behind Lustriva — Kalman et al. (2021) — is a randomized, double-blind, placebo-controlled trial, which is the gold standard for evaluating supplement efficacy. It was conducted over 12 weeks on 90 women with self-reported hair thinning, and it measured outcomes objectively, not through self-reported survey responses alone.

Key findings from the study:

• Significant increase in hair thickness in the Lustriva group vs. placebo at week 3, which remained significant throughout the 12 week study

• A statistically significant increase in the percent of terminal (thick, pigmented) hair and a statistically significant decrease in the percent of vellus (wispy, fine) hair.

• Reduction in the appearance of fine lines and wrinkles in the Lustriva group

Why does silicon matter for hair? Silicon (delivered here through arginine silicate) plays a role in collagen synthesis and the structural integrity of hair strands. It's found naturally in hair, skin, and nails, and is considered an important trace mineral for connective tissue health. The stabilized, highly soluble form used in Lustriva is designed to be better absorbed by the body.

Why does the form of biotin matter? Biotin is water-soluble, and standard biotin at high doses may not be efficiently absorbed, particularly in individuals who already have adequate levels. The Magnesium Biotinate form used in Lustriva is formulated for better absorption, meaning more of it may reach the tissues where it's needed.

Lustriva has also been shown to support skin health. In the same clinical study, participants using Lustriva showed a reduction in the appearance of fine lines and wrinkles — making it relevant beyond hair alone.

How Force Factor Hair Growth Accelerator Uses Lustriva

Force Factor Hair Growth Accelerator is one of a small number of consumer hair supplements formulated with Lustriva at the clinically studied 160mg dose. It's available in two formats:

• Soft Chews (Mixed Berry) — 60 soft chews per package, 2 chews daily. Individually wrapped, no refrigeration needed, and formulated with Vitamins C and E alongside Lustriva, which provides 10,000mcg biotin per serving.

• Capsules — 90 capsules per package, 3 capsules daily. A hair growth multivitamin that includes Vitamins A, B12, C, D, and E, plus hydrolyzed marine collagen, saw palmetto, ashwagandha, and horsetail — all alongside Lustriva at the clinically studied dose.

Both formats are manufactured in the United States in GMP-compliant facilities, and every batch is third-party tested for identity, purity, and quality.

Hair Growth Accelerator Soft Chews are particularly popular for their format innovation — individually wrapped, flavored chews that make a daily supplement ritual enjoyable and easy to stick with. The capsule formula offers a broader nutritional profile for those seeking a more comprehensive hair and wellness supplement.

How Does Hair Growth Accelerator Compare?

With a growing number of hair supplements on the market, it's worth understanding how they differ — particularly on the question of whether their key ingredients have direct clinical backing.

The table below compares Force Factor Hair Growth Accelerator to two other commonly purchased hair supplements:

What to Expect — And When

Managing expectations is one of the most important things a hair supplement brand can do — and one of the least commonly done well. Here's a realistic breakdown of what the research and the hair growth cycle suggest. Hair grows in four phases: anagen (active growth), catagen (transition), telogen (rest), and exogen (shedding). At any given time, most scalp hairs are in the anagen phase, but the entire hair growth cycle can span years. This is why hair supplements typically take time before visible results appear — our biology requires it.

Week 3: This is where the Lustriva clinical data stands out. Most hair supplements on the market make no specific timeline claims because their ingredients haven't been studied with that kind of precision. Lustriva's clinical study showed a statistically significant increase in hair thickness at week 3* — earlier than many competing products claim to work.

3 months: For fuller, denser-looking hair across the scalp, most experts and clinical frameworks measure/review hair growth and thickness results at the 90-day mark. At this point, a sufficient number of hair follicles have had time to progress through growth cycles, and the cumulative benefit of consistent supplementation becomes more apparent.

Frequently Asked Questions

What is Lustriva?

Lustriva is a patented ingredient complex that combines Inositol-stabilized Arginine Silicate with Magnesium Biotinate — a superior form of biotin and silicon. It is clinically studied and designed to support hair thickness.

Is Lustriva safe?

Lustriva has been evaluated in a randomized, double-blind clinical study with no safety concerns reported in the study population. As with any supplement, consult a healthcare professional before use if you are pregnant, nursing, have a medical condition, or take prescription medications. Individuals taking biotin doses above 2,000mcg per day should consult a doctor first, as biotin can interfere with certain lab tests and may cause adverse reactions in some individuals. If any adverse reactions occur, stop use and consult your doctor..

How is Lustriva different from regular biotin?

Standard biotin (D-biotin) has known effectiveness limitations, particularly in individuals without a deficiency. Lustriva's Magnesium Biotinate form is clinically studied to support the growth of thicker, fuller hair. It also includes Inositol-stabilized Arginine Silicate, a form of silicon that supports hair and skin health — something standard biotin supplements don't provide.

How long until I see results from Force Factor Hair Growth Accelerator?

In the clinical study for Lustriva, the key ingredient in Hair Growth Accelerator, participants saw a statistically significant increase in hair thickness as early as week 3.* With consistent supplementation, these results in hair thickness and fullness continued throughout the 3 month study.*

Is Force Factor Hair Growth Accelerator third-party tested?

Yes. Both the soft chew and capsule formulas are manufactured in GMP-compliant facilities in the United States, and every batch is third-party tested for identity, purity, and potency.

Which format is right for me — soft chews or capsules?

Both formats include Lustriva at the clinically studied dose. The soft chews (Mixed Berry flavored) are a focused formula with Lustriva, biotin, and vitamins C and E — ideal for those who want a simple, targeted daily routine. The capsule formula is a hair growth multivitamin that adds collagen, saw palmetto, ashwagandha, and a vitamin panel for broader daily nutrition support.
