Noticing a little less hair around your hairline or crown? You’re not alone! Changes in hair fullness are something many men notice over time, and they can inspire a closer look at their everyday hair care routine.
From shampoos and styling products to hair vitamins for men, there are plenty of options to explore. But when it comes to supplements, what makes one ingredient different from another?
Meet Serevelle®, the clinically studied ingredient at the heart of MaryRuth’s Hair Growth Max for Men. Let’s get to know this unique form of saw palmetto and the science behind it.
Why Do Men Notice Changes in Hair Fullness?
Hair can change with age, and two areas where men commonly notice those changes are the hairline and crown.
Some men may notice their hair looks less full than it used to, while others become more aware of how much their scalp is visible.
These changes can influence what men look for in their hair care routines, including products designed to support hair growth and fullness.
What Is Saw Palmetto?
You may have heard of saw palmetto before, but what exactly is it?
Saw palmetto is a palm plant native to the southeastern United States. Its berries contain naturally occurring fatty acids and other plant compounds, and extracts from the plant are used in certain dietary supplements.
One reason that saw palmetto has attracted interest in men’s hair research is its relationship to an enzyme called 5-alpha reductase. This enzyme helps convert testosterone into dihydrotestosterone, or DHT, a hormone associated with age-related hair thinning in men.
Saw palmetto extracts have been studied for their potential to influence this process. However, not all saw palmetto extracts are the same, and research on one specific extract doesn’t necessarily apply to every saw palmetto supplement.
What Is Serevelle®?
Serevelle is a clinically studied, concentrated bioactive fatty acids extract derived from saw palmetto.
What makes it different from standard saw palmetto? It’s a specialized, patented ingredient developed with hair health in mind, with clinical research evaluating its effects on hair growth and fullness.
In a clinical study involving adults with self-perceived hair thinning, Serevelle was shown to increase hair counts at specific measurement sites around the hairline and crown.
And the results offer an interesting look at what continued use may support!
What Did the Serevelle Clinical Study Show?
The study evaluated Serevelle with continued daily use, with results measured at 90 and 180 days.

After 90 Days: Hairline & Crown Support
After 90 days of continued use, Serevelle was clinically shown to improve hair counts at the hairline and near the crown.
After 180 Days: Fuller-Looking Hair
After 180 days of continued use, Serevelle was clinically shown to improve scalp coverage by increasing hair density and volume.
In the study, researchers also observed that men using Serevelle had:
3x greater improvement in hair density compared to placebo.
+28 hairs/cm2 with Serevelle vs. -30 hairs/cm2 with placebo.*
2.5x greater improvement in thicker terminal hairs compared to placebo.
+14 hairs/ cm2 with Serevelle vs. -25 terminal hairs/ cm2 with placebo.*
2x greater improvement in follicle density compared to placebo.
+11 follicular units/ cm2 with Serevelle vs. -20 follicular units/ cm2 with placebo.*
218% greater improvement in hairline hair density compared to placebo after 180 days.
176% greater improvement in crown hair density compared to placebo after 180 days.
Plus, 62% of Serevelle users reported that their hair looked thicker after 180 days of continued use.
These findings reflect the average results seen by men in a clinical study on Serevelle and don’t mean everyone will experience the same results.
