Why use Poly-GRO?

If you're serious about regrowing hair, you need more than just hope—you need science-backed ingredients that actually work.

Poly-GRO is powered by apple-derived procyanidin B2, a plant compound shown in clinical trials to stimulate hair follicles and promote thicker, healthier growth in those with pattern baldness. Unlike harsh treatments that rely on synthetic hormones or irritating chemicals, Poly-GRO taps into the natural regenerative power of polyphenols to extend the hair growth phase and improve follicle density.

But we didn’t stop there. We fortified Poly-GRO with caffeine anhydrous to wake up sluggish follicles. Ascorbic acid (Vitamin C) and quercetin helps defend against oxidative stress. Propylene glycol ensures deep absorption of every active ingredient, while melatonin promotes hair regeneration, increases anagen growth rate, and significantly increases hair density in clinical trials.

Procyanidin B2

Procyanidin B2 is a polyphenol (most highly concentrated in apple skins) that helps protect your body from oxidative stress that damages cells and tissues. It plays a key role in protecting your heart and blood vessels by reducing harmful fats in the blood. This polyphenol also supports healthy skin by promoting collagen production and protecting against UV damage. In clinical studies, Procyanidin B2 has shown promise in stimulating hair regrowth by boosting the activity of hair follicles, making it a powerful natural aid for reversing hair loss.

FAQs

In addition to Procyanidin B2, Procyanidin B3, and Procyanidin C1, Poly-GRO Topical contains Ascorbic Acid (Vitamin C), Caffeine Anhydrous, Propylene Glycol, Quercetin, and Melatonin to further enhance the delivery and absorption of those polyphenols for your hair regrowth.

Vitamin C protects hair follicles from oxidative stress while supporting collagen production, strengthening the scalp and hair structure.

Caffeine anhydrous stimulates blood circulation to hair follicles, prolonging the growth phase (known as anagen.)

Propylene glycol functions as a penetration enhancer, helping active ingredients like procyanidin B2 and caffeine absorb more effectively into the scalp.

We recommend applying Poly-GRO after showering, so the serum remains exposed to hair follicles.

We recommend 2 pumps twice daily for best absorption and results.
