Seller's description

Follicle Activation Complex
A multi-pathway, peptide-driven scalp serum designed to support hair density, strength, and overall scalp health. SIGNAL-CU™ combines advanced copper peptide technology with clinically supported growth and support actives to target the key pathways involved in the hair growth cycle.

Formulated with a synergistic blend of peptides, adenosine, melatonin, and circulation-support ingredients, this lightweight system helps promote a healthier scalp environment while supporting the appearance of fuller, stronger hair over time. Barrier-support ingredients like ectoine and panthenol help reduce irritation and maintain hydration, making it suitable for consistent, daily use.

Unlike single-focus formulas, SIGNAL-CU™ is built to support follicle signaling, scalp balance, and growth-cycle optimization—without heaviness or buildup.

Key Active Benefits

• Adenosine — Clinically studied to support hair growth and improve thickness over time
• Caffeine — Stimulates scalp circulation and helps energize hair follicles
• Niacinamide (Vitamin B3) — Supports scalp health, improves circulation, and helps balance oil production
• Panthenol (Pro-Vitamin B5) — Hydrates, strengthens, and improves hair shaft elasticity and shine
• Ectoine — Protects the scalp barrier, reduces irritation, and supports long-term scalp health
• Green Tea Extract — Provides antioxidant support and helps reduce inflammation and DHT-related stress
• Zinc PCA — Helps regulate oil, supports scalp balance, and contributes to a healthier follicle environment..
• AHK-Cu (Copper Tripeptide-3) — Supports follicle signaling pathways, helping improve hair density, strengthen follicles, and promote a healthier scalp environment
• Melatonin — Supports the hair growth cycle by promoting the anagen (growth) phase and reducing shedding.
