Hair Oils

Choose a hair oil by when you plan to use it and the finish you want.

Choose by routine

• Before shampooing: Mermaid Nourishing Prewash is a rich oil for dry-feeling lengths and ends before washing. See all pre-wash hair oils.
• Finish damp or dry hair: Ocean Breeze, Golden Siren, Desert Queen, Mermaid Melon, Atlas Amber and Mermaid Hair Shine are lightweight finishing oils for softness, shine and a smoother-looking finish.
• Two-step routine: Mermaid Hair Duo pairs a pre-shampoo oil with a finishing oil.
• Single-ingredient, fragrance-free care: Pure Castor Oil is a richer, multi-use option for lengths, ends and targeted dry areas.

Each option is available in 30 ml and 60 ml. Product pages show published directions, scent information and formula details when available.

Looking for shine? Lightweight finishing oils in this collection are made for damp or dry hair when you want softness and a smoother-looking finish—not a heavy pre-wash treatment.
