Follicium XR™ – The World’s First Max Strength RU58841 Hair Spray Serum!
The Core Objective of Follicium XR™
✔ Maintain follicles in active anagen
✔ Reduce androgen-driven miniaturisation
✔ Improve scalp circulation and metabolic activity
✔ Enhance hair fibre anchorage and thickness
ROK Medical proudly introduces Follicium XR™, a lighter, sprayable evolution of our breakthrough Follicium™ Serum.
Developed for anytime, anywhere use, Follicium XR™ makes max-strength RU58841 science accessible in a refreshing daily spray.
Together, Follicium™ Serum + Follicium XR™ Spray can be used for round-the-clock treatment, or either may be used individually depending on lifestyle and preference.
Building on the foundation of Follicium™ Serum, Follicium XR™ includes the same clinically proven actives as Follicium™ Serum with an additional growth factor in the form of AHK-Cu.
The Science Behind Follicium XR™
🔬 RU58841 (5% w/v) – At the foundation of Follicium XR™ is topical anti-androgen protection. RU58841 works by locally blocking androgen receptor activation in the scalp, preventing DHT from triggering follicle miniaturisation — without systemic hormonal disruption.
🔬 AHK-Cu – (1%), is the hero peptide of Follicium XR™ — chosen specifically for its role in IGF-1 signalling, follicle thickening, and density optimisation.
🔬 GHK-Cu Peptide (1%) – Enhances circulation, repairs follicle tissue, and reduces inflammation for stronger, healthier regrowth.
🔬 Caffeine (2%) – Stimulates follicle activity, prolongs the growth phase, and increases hair density.
🔬 D-Biotin (1%) – Essential for keratin production, improving strength, shine, and resilience.
🔬 Methylene Blue (Oxidised) (0.1%) – Mitochondrial antioxidant that restores cellular energy and follicle vitality.
🔬 Keratin (1%) – Strengthens shafts, reduces breakage, and thickens hair fibres.
🔬 Spermidine (1%) – A polyamine linked to autophagy and cellular renewal, shown to stimulate follicle stem cells, extend the anagen (growth) phase, and promote visibly denser, healthier hair.
The AcCELLer8™ Matrix — The Hidden Advantage
Beyond headline actives, Follicium XR™, like all Follicium™ products, is built on the AcCELLer8™ Matrix — a proprietary support system of vitamins, minerals, humectants, and metabolic cofactors.
The AcCELLer8™ Matrix:
Optimises follicular energy availability
Supports keratin synthesis and cell turnover
Maintains barrier integrity
Reduces oxidative and inflammatory stress
This ensures that every signalling molecule has the cellular infrastructure it needs to work effectively, transforming isolated actives into a coherent biological system.
