EO Grapefruit & Mint Shampoo Refill is a 1-gallon, sulfate- and paraben-free hydrating shampoo formulated with grapefruit and peppermint essential oils to gently cleanse and moisturize all hair types.

This concentrated 1-gallon refill offers the bright citrus of grapefruit paired with cooling peppermint for an uplifting scent profile while delivering moisture from nutrient-rich botanicals.

The formula is free from sulfates and parabens and aims to maintain hair softness and manageability without stripping natural oils.

How do I use the 1-gallon refill at home without waste?

Pour the refill into smaller pump or squeeze bottles to reduce spills and make daily use convenient. Use warm water to open the hair cuticle, apply a quarter-size amount (more for longer hair), lather from roots to ends, then rinse with cool water to help seal the hair surface.

• Refill into 8–16 oz pump bottles for easy dispensing.
• Use warm water first, then cool rinse to preserve shine.
• Apply scalp massage for improved cleansing and relaxation.
• Store out of direct sun to protect essential oils.

What scent and sensory experience can I expect?

The fragrance blends bright grapefruit top notes with sharp, cooling peppermint to create an awakening citrus-herbal aroma. It’s designed to feel refreshing at the scalp and leave hair smelling clean without an overpowering perfume finish.
