Why we like it
The Moda Team Review
OLAPLEX is carried at Moda because clients ask for it by name. The 1000ml duo is for committed OLAPLEX wash routine users who want the system covered at better value.
Read full stylist notes
The client with waist-length colour-treated hair who goes through a standard Nº.4 in 5 or 6 weeks and finds it inconvenient to keep reordering. The 1000ml duo lasts her 4 to 5 months and the per-wash cost drops meaningfully. OLAPLEX pioneered bond building. The 1000ml duo is the professional-scale version of the brand’s most used wash system for clients who have made OLAPLEX their daily routine.

How to use
Use it the way we would.
- Shampoo: Apply a small amount to wet hair, lather with water, rinse.
- Conditioner: Apply through mid-lengths and ends, leave briefly, rinse well.
Moda stylist tipKeep conditioner focused through the mid-lengths and ends unless the directions say otherwise. Softness belongs where hair needs it most.
Reviews
Questions? We get them.
Good to know.
The questions we hear most about this product. If yours isn’t here, a real stylist will answer.
Ask ModaIs the 1000ml formula identical to the standard size?
Yes — identical formula. The larger size exists for value and convenience, not a different formula. If the standard Nº.4 and Nº.5 are working well for you, the 1000ml delivers the same result with better per-wash cost.
How long does the 1000ml duo last with regular washing?
Yes — with 3–4 washes per week on medium-length hair, the 1000ml bottles typically last 4–6 months each. Exact usage depends on hair length, thickness, and how much product is used per wash.
Should I try the standard sizes before committing to 1000ml?
Yes — if you haven't used OLAPLEX Nº.4 and Nº.5 before, start with the standard duo to confirm the system suits your hair before committing to the larger size.
Do I need a pump dispenser for the 1000ml bottles?
Yes — a pump dispenser is highly recommended for 1000ml bottles for consistent dosing and to avoid over-dispensing. Contact us at hello@modasalon.ca for pump availability.
Is the 1000ml duo suitable for fine hair?
No — for fine hair, Nº.4 FINE and Nº.5 FINE are the correct products. The standard Nº.4 and Nº.5 (in any size) have a richer moisture profile that can weigh fine hair down.
