Most Hair Supplements Only Address Half the Problem
Dr. Gene Bruno, DBM, MS, RH(AHG) · Nutra Spotlight · June 2026
Two Ingredients. Two Pathways. One Science-Backed Approach to Hair Health.
A lot of people are interested in taking supplements that might help with their hair health. But what it really comes down to are the ingredients — and whether they have any science to support them.
There are actually two ingredients that work really well. One is saw palmetto extract and the other is a specialized combination of biotin and silicon. What makes them especially interesting is that they work by completely different mechanisms — which means together, they address hair health more completely than either one could alone.*
Why two pathways matter: Hair thinning has multiple contributing factors — hormonal, structural, and nutritional. An ingredient that targets only one mechanism leaves the others unaddressed. Using two complementary pathways simultaneously gives your hair the most complete support possible.*
Two Ingredients, Two Pathways
Serevelle™ supports the hormonal pathway. Lustriva® supports the structural pathway. Together, one formula.*
Ingredient 1
Serevelle™ — The Saw Palmetto Extract Backed by a Randomized Controlled Trial
Saw palmetto extract helps modulate certain hormones, and that can be beneficial for hair. But not all saw palmetto extracts are created equal. Serevelle™ is a trademarked, standardized form — and it's the one with the clinical research behind it.
In a randomized, double-blind, placebo-controlled study, Serevelle™ improved hair growth and hair thickness while reducing hair shedding. Most strikingly, hair counts in the Serevelle™ group were approximately 7 to 12 times greater than those in the placebo group.*
Serevelle™
Follicle environment + growth cycle support, clinically studied to support hair density and thickness.*
Serevelle™ Clinical Study Findings*
Hair Growth
Clinically shown to improve hair growth in a randomized, double-blind, placebo-controlled study*
Hair Thickness
Improved hair thickness versus placebo in the same controlled trial*
Reduced Shedding
Participants experienced meaningful reductions in hair shedding with consistent use*
7–12x Hair Counts
Hair counts in the Serevelle™ group were approximately 7 to 12 times greater than those in the placebo group*
The mechanism? Saw palmetto extract helps modulate certain hormones related to the hair growth cycle. By supporting healthy hormone balance, Serevelle™ may help address one of the underlying factors associated with thinning hair.*
"Hair counts in the saw palmetto group were about 7 to 12 times greater than those in the placebo group. Serevelle™ as the saw palmetto extract is a really good way to go."

Ingredient 2
Lustriva® (MB40X™) — A Specialized Biotin-Silicon Combination
Biotin is everywhere in hair supplements — and for good reason. Biotin helps with an enzyme that stimulates keratin production, and keratin is the structural protein that makes up your hair.
But there's a special form of biotin — magnesium biotinate — that's combined with a form of silicon called inositol stabilized arginine silicate. This combination is the science behind Lustriva® (MB40X™).
Lustriva® (MB40X™)
↑ Thickness
Increased hair thickness in clinical studies*
The Lustriva® blend was shown to increase measurable hair thickness with consistent daily use.*
Lustriva® (MB40X™)
↓ Shedding
Improved hair growth and reduced hair shedding*
Participants also experienced improvements in hair growth alongside meaningful reductions in shedding.*
Why not regular biotin? Standard biotin is water-soluble and excreted quickly. Magnesium biotinate (the biotin form in Lustriva®) offers enhanced stability and utilization, while the inositol stabilized arginine silicate component supports the structural integrity of the hair shaft itself.*
The Dual-Pathway Approach
Why They Work Better Together
It really makes sense to use both of them together because they work by different mechanisms. Serevelle™ works at the hormonal level — helping modulate hormones related to the hair growth cycle. Lustriva® works at the structural level — supporting keratin production and hair shaft integrity.*
One addresses why hair thins. The other supports how hair grows. Together, they form a more complete approach to hair wellness than either ingredient could provide alone.*
Two Mechanisms, One Hair Shaft
Lustriva® supports structure. Serevelle™ supports the follicle and growth cycle. Different jobs, same goal.*
Two Pathways, One Formula
Serevelle™ — Hormonal Pathway
Helps modulate hormones related to the hair growth cycle*
Lustriva® — Structural Pathway
Supports keratin production and hair shaft structure for thicker, fuller-looking hair*
The Product
Putting the Science Into Practice: MyBiotin® Growth+™
MyBiotin® Growth+™ by Purity Products® is a next-generation hair wellness formula that brings both ingredients together in one daily supplement — Serevelle™ saw palmetto extract and Lustriva® (MB40X™) — designed for women experiencing thinning due to stress, aging, or hormonal shifts.*
Unlike basic biotin supplements that address only one piece of the puzzle, MyBiotin® Growth+™ supports both hair structure and the hair growth cycle for more complete, visible results — while also supporting brows and skin from within.*
Serevelle™ Saw Palmetto Extract
The clinically studied saw palmetto extract featured in Dr. Bruno's video — shown in a randomized controlled trial to support hair growth and thickness, and help reduce shedding.*
Lustriva® (MB40X™)
A specialized combination of magnesium biotinate and inositol stabilized arginine silicate — shown to increase hair thickness, improve hair growth, and reduce hair shedding.*
- ✓Supports thicker, fuller-looking hair*
- ✓Helps reduce hair shedding*
