Strand Strong Strengthening Conditioner

A rich, strengthening conditioner that hydrates, smooths, and helps protect against breakage — leaving every strand stronger and softer.
  • Cruelty-free | Hypoallergenic | Dermatologist Tested | Refillable

Think of Strand Strong as your hair’s daily defense system. This creamy, revitalizing formula wraps each strand in lasting hydration, smoothing frizz while improving elasticity with quinoa and rice proteins. Infused with green tea, peppermint, and bergamot, it restores softness and shine while helping to strengthen weak or damaged hair. The result: resilient strands that look as healthy as they feel.

Amount: 500 ml

Instructions: After shampooing, apply to wet hair, focusing on mid-lengths to ends. Leave on for 1–3 minutes, then rinse thoroughly.

Store in a cool, dry place.

“I wanted a conditioner that didn’t just smooth my hair but actually made it stronger over time. Strand Strong keeps my curls hydrated, soft, and manageable, while also giving me the confidence that my hair is getting the nutrients it needs to stay healthy.” – Sloane Stephens

  • • Hydrolyzed Quinoa & Rice – Boost elasticity and resilience while reducing breakage
