Why we like it
The Moda Team Review
Once confirmed the system works, the litre is the smart upgrade. Same Organic Oat Milk and Avocado Oil formulas, fewer reorders, better economy.
Read full stylist notes
The client who comes back after two months and says she has already gone through the Killer Curls Rinse — she has long, thick curls, washes twice a week, and uses a generous amount each time. We put her straight on the Pro Duo. The per-wash cost drops significantly and she stops running out at the worst possible moment. Kevin Murphy was built by a session stylist on a skincare-for-hair philosophy — high-performance ingredients, lightweight formulas, sustainable packaging made from recycled ocean plastic. Moda holds White Haven status, the highest ranking Kevin Murphy awards. We carry this brand because the ingredient-first thinking matches how our team approaches every client's hair health.

Moda stylist tipGet the pumps. A 1000ml bottle without a pump in the shower wastes product and patience.
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 Pro Duo the same formula as the 250ml Duo?
Yes — identical formulas. The 1000ml is purely a volume upgrade. Same results at better value per wash.
With pumps or without?
With pumps. Tipping a 1000ml bottle wastes product. Choose without only if you already have Kevin Murphy litre pumps.
How long will the 1000ml Pro Duo last?
For medium-length curly hair washed twice weekly, typically four to six months per bottle. Dense coily hair uses more per wash; fine wavy hair uses less.
Is the Pro Duo colour-safe?
Yes — sulphate-free and colour-safe throughout both formulas.
Should I try the 250ml Duo first before buying the litre?
Yes — confirm the formulas work for your curl type with the 250ml first. Once confirmed, upgrade to the litre Pro Duo for better value per wash.
