WHAT IT IS

This intense hair repair serum improves the hair’s strength and resilience while reducing breakage and split ends. Safe for color-treated hair. Contains no added sulfates or parabens. 

WHO IT'S FOR

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.

Q&A

Is this used on damp or dry hair? All over, or just the ends? Thx.
Hi Donna, This can be used on damp or dry hair, and can be applied midshaft to ends.
Do I use this on wet or dry hair? The instructions don't really give much detail.
Hi JM, You can use this on wet hair before you blow dry, or you can also use it on your hair after it is dry to help smooth split ends.
