Men’s Re:GRO Anti-Thinning Scalp Serum 3-Pack

Suitable for all hair types
9.0 oz / 255 g

We were tired of pricey treatments, harsh ingredients, and sticky serums — so we made something better.

Men’s Re:GRO™ Anti-Thinning Scalp Serum is a clean, concentrated serum with 5% Capixyl®, a clinically studied peptide complex shown to enhance hair density over time.* No toxins, no scary side effects — just real results powered by proven ingredients like caffeine, biotin, rosemary, and saw palmetto.

This non-sticky, non-greasy serum glides on with a breezy, cooling finish that’s easy to apply and doesn’t weigh hair down. This trio gives you a full 12-week supply — the amount recommended for visible results.

Benefits

  • Builds visible thickness and fuller hair over time
  • Reduces shedding and helps fight receding areas
  • Energizes and strengthens hair follicles with no mystery chemicals
  • Adds instant lift at the roots
  • For best results, incorporate Men’s Re:GRO™ Anti-Thinning Scalp Serum into your routine 4x per week for 12 weeks. (3 bottles will get you there.)

Key Ingredients

  • 5% Capixyl® – Clinically shown to spark new growth and strengthen thinning hair.*
  • Caffeine – Like coffee for your scalp — wakes up follicles and boosts circulation.
  • Biotin – Strengthens strands and reduces brittleness for healthier hair.
  • Botanical Oils – Rosemary, Castor, and Pumpkin Seed nourish the scalp and promote fullness.
  • Saw Palmetto – Helps block DHT (the shedding hormone) to keep hair stronger, longer.
  • Silica (from rice) – Helps lift roots and give you an instant thickness boost.

Hair loss is personal—
so we made the solution personal, too.

Our founder, Shelby, created Re:GRO™ after seeing too many people struggle with thinning hair - including herself. The solutions out there were either expensive, limited, packed with sketchy ingredients, or simply didn't deliver.

She turned to her garden—mixing herbs with clean oils—and for the first time, saw real change. That simple blend became our Re:GRO Collections. Shop the full Men’s Re:GRO Anti-Thinning Collection now:
