Why we like it
The Moda Team Review
OLAPLEX is carried at Moda because clients ask for it by name. It pioneered the bond-building category and Nº.0 is the product that elevates the at-home treatment for clients with heavily processed hair. For those clients, Nº.0 + Nº.3 together is the correct protocol, not just the shampoo and conditioner.
Read full stylist notes
The client with bleached hair who has been using Nº.3 weekly but still notices significant breakage and brittleness between appointments. We move her to Nº.0 + Nº.3 together. After four to six weeks she reports noticeably less mid-length snapping during detangling and more elasticity through damp hair — the benchmark we use to assess structural improvement. OLAPLEX created the bond-building category. Before it existed, there was no at-home option for reconnecting broken disulfide bonds. Moda carries OLAPLEX because our clients ask for it by name and trust the science. We recommend Nº.0 when the hair genuinely needs more than Nº.3 alone can deliver.

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 ModaDo I actually need Nº.0 if I'm already using Nº.3?
No — Nº.3 alone delivers meaningful bond repair. Nº.0 is a primer that opens the hair cuticle before Nº.3 to allow deeper penetration. It's the right step up when Nº.3 alone isn't delivering enough for heavily bleached or repeatedly processed hair.
How long does Nº.0 need to sit before I apply Nº.3?
Yes — apply Nº.0 to dry hair, leave for 10 minutes, then apply Nº.3 on top without rinsing in between. The two products work together in the same application window.
Can I use Nº.0 every week, or is it too intense for regular use?
Yes — weekly use is appropriate and the intended protocol. OLAPLEX bond-building technology works cumulatively; consistent weekly use delivers progressively better results over time rather than a single-use fix.
My hair is already pretty healthy — would Nº.0 do anything for me?
No — if your hair is only mildly processed and Nº.3 is already delivering visible improvement, Nº.0 adds limited benefit. It's designed for hair that has been significantly compromised and isn't responding enough to Nº.3 alone.
Can I use Nº.0 before a colour appointment to protect my hair?
No — Nº.0 is a pre-wash at-home treatment, not a pre-colour in-salon step. Do not apply Nº.0 immediately before a colour service. Your stylist uses OLAPLEX in the colour formula itself. Use Nº.0 + Nº.3 in your home routine in the weeks around your appointment.
