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
- Warm a little pre-wash oil and work through dry mid-lengths and ends (scalp too, if you like).
- Leave 30–120 minutes — overnight is fine for very dry hair.
- Shampoo thoroughly (two lathers if needed).
- 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)
- Argan + camellia in the finishing oil
Before you buy
Which oil goes first?
Pre-wash on dry hair before shampoo. Finishing oil after you rinse — damp or dry ends.
Will it grow my hair?
We don't make growth claims. This set is for softness, manageability, and shine — and helping reduce the look of breakage so you keep the length you have.
Just want the pre-wash?
You can buy the Mermaid Batana & Rosemary Pre-Wash on its own ($23.99).
What about Free shipping CA$75 / US$100. At $44.99, add a small oil (like castor) and a lotion to clear it in one order.
External use only. Patch test first.
