A 6-pack of the only hair growth serum with clinically relevant amounts of genuine apple Procyanidin B2. A higher concentration of the successful formula used in multiple male pattern baldness trials. Plus added polyphenols and select regrowth agents. Drug free. No side effects. No unpleasant odor. No irritation. Promotes the health of your skin and scalp. Discreetly packaged in a pump spray for ease of application.

Spray 2 pumps twice daily and massage into your scalp (ideally after showering, so the serum remains exposed to hair follicles.)

  • Contains clinically relevant amounts of Procyanidin B2 (the specific apple polyphenol shown to regrow hair in pattern baldness trials)
  • Contains the supporting polyphenols Procyanidin B3 and Procyanidin C1, which also show hair regrowth properties
  • Contains ascorbic acid (Vitamin C) which protects hair follicles from oxidative stress while supporting collagen production, strengthening the scalp and hair structure
  • Contains caffeine anhydrous, which stimulates blood circulation to hair follicles, prolonging the growth phase (known as anagen)
  • Contains propylene glycol, which functions as a penetration enhancer, helping active ingredients like procyanidin B2 and caffeine absorb more effectively into the scalp.

Each batch of Poly-GRO is standardized and concentrated to 400% strength from the formula used in pattern baldness clinical trials.

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) helps defend against oxidative stress, while propylene glycol ensures deep absorption of every active ingredient.

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.Quercetin and Melatonin are powerful antioxidants that both show strong hair growth promotion in recent studies.

We recommend applying Poly-GRO to the scalp once or twice daily, and after showering when pores are open. Most clinical trials feature twice daily application. Apply Poly-GRO before using any oil-based hair or scalp treatment. Important: massage gently for 60 seconds to enhance absorption.

A 1 (one) ml draw with the pipette (included with your order), or 5 (five) full spray pumps, equals the recommended amount for one application.

Poly-GRO topical serum remains viable for 12 months, properly stored, from the date of purchase.

Yes––for lasting potency, it is best to store Poly-GRO in a cabinet or drawer away from light.

    Stronger Thicker Hair

    I've been using Poly-GRO for a few years now, along with the ApplePoly capsules. I can tell a significant difference between with I am using them vs not. My hair and fingernails grow much thicker and stronger while using these products. I've personally noticed that the capsules also have a host of other benefits to immune system and skin health. I put myself on a monthly subscription, and it's great to have it delivered on a regular basis - no worries about remembering to reorder. It's great. Highly recommended.

    I've seen my hair grow back

    This stuff really works. I've seen my hair grow back. I'm highly allergic and very sensitive to chemicals, and I lose hair when I have an allergic reaction. When I use Poly-GRO, my hair grows back in thicker.

    I've bought a lot of different products in the past

    This really works! I've bought a lot of different products in the past and this is the only stuff I'd ever spend money on for hair re-growth. I now have hair covering my forehead and freckles, where I had not had hair for a long time.

    I didn't really expect it to work

    I’ve been using your Procyanidin B-2 product. I'm 81 years old. I didn't really expect it to work, but I've got a bunch of new growth on top. It's like new stubble, it hasn't gotten long yet, but I'm hoping that's next.
