Dyson Define & Refresh Styling Duo — 2‑Piece Travel Hair Set with Strengthening Leave‑In & Chitosan Styling Spray, Heat Protection

Dyson Define & Refresh Styling Duo is a two-piece luxury hair set with a strengthening leave-in conditioning spray and a chitosan-based multi-use styling spray to nourish, protect and hold styles for all hair types.

This compact pair combines targeted hair repair with reliable style memory so you can protect strands while finishing or refreshing your look. The collection pairs Dyson Omega™ Leave-in conditioning spray — formulated with a blend of omega-rich oils to reduce breakage and guard against heat up to 450°F — with Dyson Chitosan™ Multi-use styling spray, designed to define finishes and revive second-day hair without stiffness. Both offer signature fresh fragrances and are travel-friendly for on-the-go touchups.

How does the leave-in conditioning spray strengthen and protect my hair?

The Dyson Omega leave-in uses a concentrated Oli7 oil blend to feed weakened keratin and help reduce breakage when styling. It also provides heat protection that supports styling tools up to 450°F, so strands are better shielded during blow-drying or thermal styling.

• Oli7: seven omega-rich oils including sunflower seed oil sourced from Dyson Farms.
• Reduces breakage compared with untreated hair, helping hair look healthier and shinier.
• Formulated to protect against heat up to 450°F for safer styling sessions.

What does the chitosan styling spray do for finished looks or day-two hair?

Dyson Chitosan multi-use spray contains chitosan derived from oyster mushrooms plus amino acids and bamboo extract to lock in shape and smooth the hair surface. It holds and defines the end style, or refreshes and reworks hair between washes without a crunchy finish.

• Chitosan and amino acids provide flexible hold and definition.
• Bamboo extract helps smooth and control frizz, even in humid conditions.
• Works to revive styles for second-day hair without heavy residue.

Will this duo weigh my hair down or make it greasy?

Both formulas are tuned for lightweight performance: the leave-in conditions and strengthens without coating strands, and the styling spray delivers hold without stiffness. They were developed to maintain shine and manageability across fine to coarse hair types.

• Lightweight leave-in oil blend absorbs without heavy buildup.
• Styling spray provides flexible hold rather than a hard film.
• Suitable for routine use and convenient travel sizes for touchups.

Who this set is for: If you want a compact, salon-quality pairing that repairs, protects from heat, fights humidity and keeps styles looking fresh, this duo is built for you. It’s ideal for anyone who uses heat tools, needs a fast midday refresh, or prefers products that combine nourishing ingredients with styling performance. The travel-ready sizes and refined fragrances make it a practical addition for commuters, frequent flyers, and anyone seeking consistent, resilient results between washes.
