Mermaid Hair Duo – Pre-Wash & Nourishing Hair Oil Set

The Mermaid Hair Duo is wash day, covered: the Batana & Rosemary pre-wash oil (60 ml), plus a lighter Argan & Camellia oil (30 ml) for after you rinse. Soften first, then smooth and shine — without buying two bottles separately.

What's in the set

• 60 ml Batana & Rosemary Pre-Wash Oil. On dry hair before shampoo. Leave 30–120 minutes, then wash. Softens dry lengths and makes hair easier to manage.
• 30 ml Argan & Camellia Nourishing Hair Oil. A few drops on damp or dry ends after washing for softness and shine that doesn't feel heavy.

How we use it

1. Warm a little pre-wash oil and work through dry mid-lengths and ends (scalp too, if you like).
2. Leave 30–120 minutes — overnight is fine for very dry hair.
3. Shampoo thoroughly (two lathers if needed).
4. After washing, smooth a few drops of the Argan & Camellia oil through ends.

Most people use the pre-wash 1–2 times a week.

What you'll notice

• Softer, smoother-feeling hair after wash day
• Less of that rough, snapped-looking feel on dry lengths
• A light shine from the finishing oil — not a greasy coat

Key ingredients

• Batana + rosemary in the pre-wash (with jojoba, grapeseed, argan, black seed, vitamin E)
