Key Benefits

This 100ml serum delivers clinically proven results:

  • Reduces hair loss by targeting the root causes of thinning and breakage
  • Increases hair density — 94% of users showed improvement after 60 days of daily use
  • Strengthens from the scalp using biomimetic peptides (Acetyl Tetrapeptide-3) that revitalise follicles
  • Lightweight and non-greasy — absorbs quickly without weighing hair down
  • Warm floriental fragrance with notes of mandarin, jasmine, and vanilla

How to Use

For best results, use daily as part of your hair care routine:

  1. Apply to clean, towel-dried scalp — section hair and apply directly to the scalp
  2. Massage gently to stimulate circulation and help absorption
  3. Do not rinse — leave in and style as usual
  4. Use consistently for at least 60 days to see visible improvements in density and strength

Pairs beautifully with Keune Long & Strong Shampoo and Conditioner for a complete strengthening routine.

Who It's For

Ideal for anyone experiencing:

  • Thinning or fine hair that lacks volume and body
  • Fragile hair prone to breakage from colouring, heat styling, or everyday wear
  • Visible hair loss or slower growth over time
  • All hair types — the lightweight formula suits everyone

This serum is perfect if you're looking for a professional solution to support healthier, fuller-looking hair without salon visits between appointments. Your stylist at Honeys Hair & Beauty in Taunton can advise on how to integrate this into your routine.

Active Ingredients

The formula combines science-backed actives for visible results:

  • Biomimetic Peptides (Acetyl Tetrapeptide-3) — mimic natural growth signals to extend the hair cycle
  • Biotin — essential vitamin for hair strength and health
  • Caffeine — stimulates the scalp and improves microcirculation
  • Panax Ginseng Root Extract — energises and revitalises
  • Trifolium Pratense (Clover) Flower Extract — supports a healthy scalp environment
  • Hydrolyzed Soy Protein — reinforces hair fibres

Please note: Contains alcohol denat., which may be drying for very sensitive scalps. A patch test is recommended if you have scalp sensitivities.
