🧠 What Is Rosemary CO₂ Extract?

Rosemary CO₂ extract is a highly concentrated botanical extract obtained through supercritical carbon dioxide extraction — a eco-friendly, non-toxic, low-temperature method that preserves the full spectrum of rosemary’s bioactive compounds without the need for heat or chemical solvents.

Compared to rosemary essential oil or infusions, the CO₂ version is more stable, potent, and gentle, making it ideal for those with sensitive skin or scalp issues. Rich in carnosic acid, rosmarinic acid, and antioxidants, it provides therapeutic-grade benefits with no synthetic additives.

💧 Hair & Scalp Benefits of Rosemary CO₂ Extract

  • Stimulates Hair Growth
     Enhances scalp circulation and promotes oxygen and nutrient delivery to hair follicles — encouraging fuller, faster growth.
  • Reduces Hair Thinning & Loss
     Shown to reduce DHT buildup around hair follicles, which can be a contributing factor in androgenic hair thinning.
  • Fights Scalp Inflammation
     Anti-inflammatory compounds calm irritated, flaky, or itchy scalps, supporting a healthy microbiome and hair ecosystem.
  • Antioxidant Shield
     Packed with powerful antioxidants that protect follicles from oxidative stress caused by pollution, UV exposure, and styling damage.
  • Natural Preservative Properties
     Its antimicrobial and antifungal qualities help keep formulations fresh without synthetic preservatives.

🔬 The Science Behind It

A 2015 study published in SKINmed Journal showed that rosemary extract was as effective as 2% minoxidil in promoting hair growth over a six-month period — without the side effects like itching or scalp dryness.

Rosemary CO₂ extract’s ability to inhibit 5-alpha-reductase (the enzyme that converts testosterone to DHT) is well-documented in pharmacological literature. Additionally, its carnosic acid has been shown to repair nerve damage in the scalp, potentially reactivating dormant hair follicles.
