Description: Start reversing hair age in 3 months to reduce shedding, greying and scalp ageing. Lightweight serum is clinically proven to deliver up to 19,000 more hairs, fewer greys, and improved scalp barrier, powered by proprietary MultiVital™ technology

Key Benefits:

  • Reduces hair shedding and increases density by strengthening root anchorage and protecting proteins that keep hair anchored in place
  • Delays and reverses premature greying by supporting melanin transport and synthesis pathways, helping reduce the appearance of greys by up to 70%
  • Fortifies scalp health and barrier function with targeted oxidative defence against environmental stressors, UV, and lifestyle factors
  • Lightweight and non-greasy, with zero heavy buildup or oily residue, making it ideal for nightly use on both wet and dry scalps

How to Use: Apply 4 droppers, filled to the line, directly to a damp or dry scalp, using one dropper each at the middle part, side part, and hairline, then distribute evenly and massage in from the hairline toward the crown and nape until fully absorbed. Do not rinse. PRO tip: put hair up for easier application.
