Key Features

Targeted Multi-Layer Technology

This hair density serum works in sophisticated layers: water-based ingredients hydrate the scalp's surface, while deeper actives, such as acetyl tetrapeptide-3 and caffeine, penetrate to support follicle vitality and long-term regrowth. Each use supports stronger, healthier-looking hair - from root to tip.

• Biotin Complex (Biotin & Biotinyl Tripeptide-1): Reinforces hair structure, encouraging robustness and resilience starting at the root.
• Caffeine & Plant Flavonoids (Apigenin): Revitalises and energises any tired scalp, supporting a balanced, extended hair growth cycle for visible density and strength.
• Advanced Peptides (Acetyl Tetrapeptide-3): Help promote a healthy scalp environment, soothing irritation and supporting regrowth.
• Moisture Blend: Glycerin, propylene glycol, and butylene glycol combine for lightweight hydration and scalp comfort, locking in moisture without heavy residue.
• Clean, Non-Comedogenic, Silicone-Free Formula: PH-balanced at 5.5, vegan-friendly, and suitable for daily use, even on sensitive skin.
• Fast-Absorbing, Non-Greasy: Optimised for daily application so you immediately style your hair after use - no wait, no mess.
• Antimicrobial Support (Biota Orientalis Leaf): Provides additional care for scalp health.
