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

Benefits

  • Strengthens hair from root to tip

  • Supports healthy hair renewal with no mystery chemicals

  • For best results, incorporate Re:GRO Anti-Thinning Scalp Serum into your routine 4x per week for 12 weeks for best results. (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 (shedding hormone) to keep hair stronger, longer.

Good for:

  • Thinning hair and early signs of hair loss

  • Weak, brittle, or breakage-prone strands

  • Dry, oily, or unbalanced scalp conditions

  • Tension from tight or protective hairstyles like braids, buns, weaves or ponytails.

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

Our founder, Shelby, was inspired to create our Re:GRO™ Anti-Thinning Scalp Serum by her struggles with postpartum hair loss. Everything she tried was either expensive, full of sketchy ingredients, or just didn't work.

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.

    Changed my hairline!!!

    I've struggled with hair thinning & loss around my hairline, and using this a few times per week has completely changed the game for my hair growth around my hairline. It's thicker, and I've seen re-growth even in the bald spots! Having something affordable and effective is SO hard to find and this actually worked. Be sure to keep up with it and you will see results!

    I love the way it smells, and the way it makes my hair feel. I have used it 4 times and feel like my hair is falling out less already.
