Why we like it

The Moda Team Review

As a White Haven Kevin Murphy salon, the Smooth Again Duo is the starting point for every thick or frizz-prone client. Both products work in sequence with Monoi Oil at every step — the Wash deposits it, the Rinse’s Biomimetic Keratin adds structural smoothing on top. The cool water final rinse locks in both.

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 Moda
Should I get this duo or the Pro Duo in 1000 ml?

Start with the 250 ml if you have not used the SMOOTH AGAIN system before. Use it for 6 to 8 weeks to confirm the formulas work for your hair. If you love them, the Pro Duo is significantly better value per wash.

Do I also need Smooth Again Treatment or is this duo enough?

The duo is a complete shower routine. Add the Treatment if your frizz returns between styling sessions — it creates a humidity barrier that protects the smooth result through the day. Most thick-haired clients in humid conditions benefit from all three steps.

I have thick colour-treated hair. Is this duo safe post-colour?

Yes — both are sulphate-free and colour-safe. Sulphate-free shampoo is what your stylist recommends post-colour to extend the service. The frizz control in Smooth Again Wash and the Biomimetic Keratin in Smooth Again Rinse are compatible with colour-treated thick or wavy hair.

How long will the 250 ml duo last?

Most clients with thick shoulder-length hair get 5 to 7 weeks from each 250 ml bottle. Thick hair typically uses more product per wash than fine hair. The Rinse may last slightly longer since it is applied mid-lengths to ends only.

Does the cool water rinse really make a difference on thick hair?

Yes, measurably. Cool water closes the cuticle scales after the Biomimetic Keratin and Monoi Oil have smoothed them, locking in the result. Hot water re-lifts the cuticle. 10 to 15 seconds of cool water at the end of the Rinse step extends how long the smooth result holds through the day.
