Pre-Wash vs Leave-In Hair Oil

Pre-wash hair oil and leave-in finishing oil solve different moments in a wash day. Mixing them up is the most common reason a hair oil feels too heavy or does nothing.

Pre-wash (before shampoo)

Apply to dry hair, leave on for the time on the product page, then shampoo out. Use the pre-wash hair oils collection for batana and rosemary options such as Mermaid Batana & Rosemary Pre-Wash Oil.

Leave-in / finishing oil

Use a few drops on damp or dry lengths and ends after washing. Mermaid Hair Shine is the finishing pathway for soft, shiny-looking lengths.

Quick chooser

• Hair feels dry before wash day → pre-wash oil
• Ends look dull after washing → finishing shine oil
• Want both → Mermaid Hair Duo
