Polyamines Promote Hair Growth and Strengthen the Follicle–Here’s How to Incorporate Them

When it comes to super ingredients we take notice, especially when they’re clinically proven. There’s a newcomer in town that’s buzzing through the hair set: polyamines. Touted to repair and refine hair cuticles, promote hair growth and strength the hair follicle, we knew we had to take a closer look.

To get the 411 on all things polyamines–including how to incorporate them into our own hair routines–we checked in with Brian Oh, CEO and co-founder of VENN to break down what polyamines are and how they can help out our distressed tresses.

What are Polyamines?

Polyamines are actually all around us. They are natural compounds that are found in all living organisms, including humans and plants. “They contain spermidine, putrescine and spermine, which have been linked to having antioxidant and anti-inflammatory properties,” shares Brian.

Polyamines play a significant role in cell growth, survival and proliferation. “Their levels decline continuously with age, while studies have shown that their supplementation increases the life span in model organisms. When it comes to hair, polyamine is clinically shown to repair and refine hair cuticles, promote hair growth (measured efficacy similar to minoxidil) and strengthen scalp and hair follicles,” he continues.

Where Do They Come From?

Being classified as organic compounds, polyamines are naturally occurring. While they are prevalent in all domains of life, they can be found at highest concentrations in soybeans and green tea (especially matcha), fermented products, nuts and seeds, and so on. The polyamines in VENN products are derived from soybeans.

Benefits for the Scalp and Hair

“Studies show that due to the cell-stimulating properties of polyamines, they can be a powerful tool in supporting hair growth. More specifically, they activate the hair follicle keratinocyte to elongate the hair growth phase and thereby strengthen the hair shaft. They also increase the hyaluronic acid production,” says Brian, noting that VENN’s Synbiotic Polyamine Shampoo deeply nourishes and strengthens the hair and scalp.

The best delivery

Polyamines in all forms are good for you; most studies are focused on the topical application and reveal benefits for both the hair and skin. There are also studies that demonstrate the exogenous/supplementary administration of polyamines (including through food and water) “increased endogenous levels and increased the life span in model organisms.”

Clinical results

VENN’s Synbiotic Polyamine Shampoo was clinically tested to significantly improve scalp elasticity, reduce scalp sebum, reduce dandruff (dead skin cells), and cleanse hair to remove dirt and impurities. Brian shares the results from a recent study: 

  • Clinical Test #1: Assessment of Scalp Elasticity Improving Effect
    • After using VENN Synbiotic Polyamine Shampoo once every day, for 28 days, scalp elasticity increased on average by 18.16% and 47.78% after 2 weeks and 4 weeks, respectively (27 participants, statistically significant at p<0.001).
  • Clinical Test #2: Assessment of Scalp Sebum Removal Effect 
    • After using VENN Synbiotic Polyamine Shampoo once every day, for 28 days, scalp sebum reduced on average by 17.76% and 18.6% after 2 weeks and 4 weeks, respectively (27 participants, statistically significant at p<0.001)
  • Clinical Test #3: Assessment of Scalp Dead-Skin Improving Effect 
    • After using VENN Synbiotic Polyamine Shampoo once every day, for 28 days, scalp dead skin reduced on average by 1.29% and 9.10% after 2 weeks and 4 weeks, respectively (27 participants, statistically significant at p<0.001)
  • Clinical Test #4: Assessment of Hair Cleansing Effect 
    • 5 times more effective than regular soap at cleansing and removing dirt and impurities from hair (25 participants, statistically significant at p<0.001)

According to another study on polyamines and hair growth, polyamines have been found crucial to hair growth as they help to rapidly regenerate tissues like the hair follicle, one of the most highly proliferative organs in biology. “Essentially, they help the hair follicle to do its job better!” he adds.

Results take about 28 days to notice, on average. In the meantime, the hair and scalp will increasingly feel and look healthier.

Polyamines plus synbiotics

The VENN Synbiotic Polyamine Shampoo combines polyamine with synbiotics—which are a combination of probiotics and prebiotic. The products are also cruelty-free and formulated without synthetic fragrance, parabens, phenoxyethanol, silicones, phthalates, mineral oil, sulfates (SLS/SLES), and colorants.
