WHY WE LOVE IT

  • Proprietary Signature Keratin helps to repair hair damage by sealing and smoothing the cuticle for healthy, frizz-free results.
  • Reinforces the hair’s structural proteins and amino acids to naturally increase hair’s strength and elasticity after just one use.
  • Reconstructs frayed hair cuticles and brittle ends by reinforcing broken keratin protein within the hair’s core.
  • Arnica Montana flower water delivers moisture and shine.

 

HOW TO USE

Shake the bottle well. Pump a small amount of serum into the palm of your hand and gently rub hands together. Apply the serum evenly, brushing hands through hair. Style as desired.
