Dyson Omega™ leave-in conditioning spray 165mL — lightweight 8-in-1 heat protection to 450°F, frizz control & cuticle sealing

Dyson Omega™ Leave-in Conditioning Spray is an 8-in-1 leave-in treatment that nourishes, seals the cuticle, reduces breakage and protects hair from heat up to 450°F for stronger, shinier-looking hair.

This lightweight, refillable 165mL formula combines a concentrated blend of seven omega-rich oils (Dyson Oli7) with a fermented complex to help hair absorb nourishment without weighing it down. Designed to work on all hair types, the spray claims measurable improvements in strength, frizz control and cuticle sealing based on laboratory testing. It also offers multi-factor protection against thermal styling, humidity, UV and mechanical damage from brushing or styling.

How does Dyson Omega™ protect hair from heat and styling damage?

The spray forms a protective barrier that helps shield strands when you use hot tools, resisting breakdown at temperatures up to 450°F. Because it seals the cuticle and reduces friction, it also helps limit mechanical breakage during combing and styling.

• Heat protection rated up to 450°F for thermal styling tools.
• Seals cuticle to reduce breakage by up to 73% versus untreated hair.²
• Lightweight fermented complex improves ingredient absorption without heaviness.
• Reduces frizz for enhanced shine and manageability.²

What benefits will I see with regular use?

With consistent application, the formula is intended to strengthen hair over time and improve surface smoothness for a shinier finish. Laboratory testing reported increased tensile strength and less visible damage when the product was used as directed.

• Nourishes now and supports strength gains—up to 94% stronger hair in tests.¹
• Improves shine by smoothing the hair surface and reducing frizz.²
• Helps reduce split ends and breakage with cuticle sealing action.²
• Fresh, delicate citrus fragrance with bergamot and mandarin notes.

How do I use Dyson Omega™ leave-in spray in my routine?

Use this spray on towel-dried or dry hair before combing, heat styling, or finishing. A few spritzes distributed along mid-lengths and ends is usually enough—focus on areas prone to dryness and breakage.

• Spritz on damp hair before blow-drying for protection and easier detangling.
• Apply to dry hair before straightening or curling to minimize thermal damage.
• Use as a daily leave-in to maintain moisture balance and reduce frizz.
