The SWE Annual Conference & Career Fair is a place where women, nonbinary individuals, and men as allies of all backgrounds can support the overall persistence and success for the engineering and technology profession of those underrepresented in the field. Those who think otherwise should reconsider attending.

Dyson is best known for revolutionising the way we style our hair with the Airwrap and Supersonic, but since moving more into the haircare space with their Chitosan styling products, it seems they are keen to expand this area of their expertise. I have been testing out the new Dyson Omega nourishing haircare range which includes the Dyson Omega Leave-In Conditioning Spray and the Dyson Omega Hydrating Hair Oil. Here’s what you need to know.
What is in the Dyson Omega Haircare Range?
There are two new haircare products in the Dyson Omega nourishing range:
The Dyson Oli7 blend combines seven omega-rich oils:

How Dyson Haircare is Made: Farming & Innovation
Dyson says, “We’ve brought together two completely different worlds – farming and beauty – to develop a product that unlocks healthy hair with natural ingredients.”
Dyson have spent over 10 years investing in and developing their precision and biodiverse farming practices. Omega is Dyson’s first product to feature an ingredient that is actually grown on the Dyson farms.
The Sunflower seed oil used in the Omega range is extracted from Dyson sunflowers seeds. They were chosen because the oil is rich in essential fatty acids, particularly omegas 6 and 9, which help to deeply moisturise the hair, smooth the cuticle, and reduce frizz. It also boasts a lightweight molecular structure, which means that the oil absorbs quickly into the hair shaft without accumulating build-up.
Additionally, a range of strategies were developed to ensure the harvested seeds contain an optimal balance of beneficial compounds. They trialled over 60 varieties of sunflower to identify those richest in natural ceramides and farmed them to optimise quality.
Hydrating Hair Oil
Dyson Omega Hydrating Hair Oil
This is a silicone-free, concentrated oil that is formulated to condition, smooth, and provide a protective moisture seal for softer, more manageable hair. It uses the Dyson Oli7 blend and is activated by a biotechnology fermented oil complex to deliver nourishment without weighing down the hair.
It is also rich in antioxidants and uses ingredients to protect against heat and mechanical damage.
Leave-in conditioning spray
Dyson Omega Leave-In Conditioning Spray
This is designed to be an 8-in-1 multitasker that:
Nourishes
Detangles
Smooths
Reduces frizz
Protects from heat
Protects from UV damage
Minimises breakage
Moisturises hair
It works to nourishes and restore dry, brittle, fragile hair and is also infused with Panthenol for added strength benefits. It comes in a fluid cream and the spray mechanism disperses it into a lightweight mist for even, controlled coverage on wet and dry hair.
My Review of the Dyson Omega Nourishing Range
First Impressions
Dyson has nailed it with packaging once again. The Leave-In Conditioning Spray is refillable (big sustainability win) and feels satisfyingly luxe in the hand. It delivers a creamy yet lightweight mist and is nourishing without ever weighing the hair down.
The Hydrating Hair Oil feels just as chic. It’s silky, absorbs quickly, and smells fresh and clean. It’s perfect for that “just-washed” vibe even on day two hair.
Dyson Omega Leave-In Conditioning Spray
Texture: A creamy formula delivered as a fine mist
How I Use It: I spritz it evenly through damp hair before brushing and styling. It makes post-wash brushing effortless and preps the hair beautifully for my Dyson Airwrap Coanda 2.0.
The Results: Once blow-dried, my hair feels soft, smooth, and hydrated without any heaviness.
The consistency of this product is really interesting as it is a thicker, more gel-like cream and quite different to a lot of leave-in sprays. The delivery system transforms this texture into a lighter mist, which I think is really clever. But clever is always what I expect from Dyson!
I love that it has heat protection and a UV shield. Also loving the refill element.
Dyson Omega Leave-In Conditioning Spray Refill
Dyson Omega Hydrating Hair Oil
If you love multi-tasking oils, this could be your new best friend.
On Damp Hair: I like to layer this over the Conditioning Spray, focusing on the ends where my hair tends to be driest.
On Dry Hair: It’s brilliant for adding softness, shine, and nourishment. I also use it to break up waves or curls post-styling for that effortless, undone finish.
This is so nice because it adds softness without being heavy and smells so fresh and clean. Again, I love that there’s heat protection in there, as I heat style my hair a lot.
Dyson Omega FAQs
Is the Dyson Omega Leave-In Spray good for fine hair?
Yes! The mist is light and creamy but never heavy. It has been formulated to work on all hair types.
Can I use the Hydrating Hair Oil on oily-prone hair?
Yes. This is a lightweight and won’t leave hair greasy. Focus application on mid-lengths to ends.
Do both products protect against heat?
Yes, both the spray and oil include heat protection as well as a UV shield.
Are the Dyson Omega products refillable?
The Leave-In Conditioning Spray is refillable.
Do they have a fragrance?
Yes, both have a subtle, fresh clean scent that feels uplifting but not overpowering.
Final Thoughts
The Dyson Omega range is a clever extension of Dyson’s haircare expertise. The Leave-In Conditioning Spray makes detangling and prep effortless, while the Hydrating Hair Oil is perfect for hydration, shine, and styling versatility. Both deliver heat and UV protection, making them hardworking essentials in any routine.
I’ve been loving them alongside my Airwrap styling sessions.
