TENSTAR
TENSTAR - Hena Color Treatment Soft Black
A hair color treatment containing original henna extract to make gray hairs less noticeable. The micro-color coat formula is gentle on the hair and scalp, and the permeating pigment settles inside the gray hairs to give it a natural tint while a moisturizing coating covers the hair's surface to prevent fading and maintains a beautiful color.

Why This Works for Your Specific Profile
Damage Index:
Healthy to moderately damaged hair experiences over-conditioning or protein overload causing limpness or rigidity
Water Quality:
Hair with breakage or thinning needs protein emphasis that moisture-heavy formula lacks
Hair:
Closed cuticles resist product penetration causing surface buildup without internal benefits
Active Lifestyle:
High activity and frequent washing rapidly strip product benefits requiring excessive reapplication
