Dyson Chitosan™ hair styling products frequently asked questions

Dyson Chitosan™ hair styling products are designed to prime and define your styles, for flexible all-day hold.* You can use the products together or separately, depending on your styling routine.

Use Dyson Chitosan™ Pre-style cream before styling, on towel-dried hair, to prime, hold and condition. Dyson Chitosan™ Post-style serum is designed for use on dry, styled hair to define, hold and hydrate your look.

Dyson Chitosan™ Pre-style cream has four formulations, precisely blended for each hair type. Dyson Chitosan™ Post-style serum is blended for all hair types.

The Pre-style cream is the foundation product for style retention. You can choose between four formulas depending on your natural hair shape and texture. When you apply to wet hair prior to styling, it will give your hair 2x longer hold* with a natural look and feel.

The Post-style serum is great for finishing your styles. You can use it to reduce frizz for a smooth finish* on straighter styles, or on natural curls to add definition.

Our Dyson Chitosan™ products are compatible with all styling routines, no matter the tool you’re using. 

However, Dyson Chitosan™ Pre-style cream and Post-style serum are the only styling products specifically designed and tested to work with Dyson hair care devices, following the same engineering mindset.

Less is more with our Dyson Chitosan™ products. We recommend starting with 2-5 pumps, building more as needed for your hair texture and length. Our Dyson-engineered applicator is rigorously tested to deliver 0.23ml every time, pump after pump, so once you’ve established the right amount for your hair, you can count on your dosage, every time. 

Identify your hair type by thinking about what shape it dries in naturally. There are four main hair types:

Type 1

Very straight hair or hair with some loose bends and waves.

Type 2

Wavy hair with a more defined S-shape.

Type 3

Curly hair with loose curls to tighter ringlets.

Type 4

Curly to coily hair with tighter corkscrew curls or closely-coiled Z-patterns.

Each hair type has different conditioning needs. The conditioning level that's right for you may depend on hair texture, chemical or color treatments, and styling routine. Visit our hair science page to learn more about identifying your hair type.

Dyson Chitosan™ products have been engineered to achieve great results on their own or when used together in your styling routine to prime and define your style for flexible all-day hold,* shiny hair, and natural movement.

Chitosan is the hero ingredient in our Dyson Chitosan™ hair styling products. Chitosan is a complex macromolecule derived from oyster mushrooms. This complex macromolecule helps create flexible bonds that support hair strand by strand, for flexible all-day hold.* It’s the foundation of our Dyson Triodetic™ technology. Our key ingredient is also supported by unique oil blends, to help condition the hair surface, reducing frizz and giving a soft, shiny finish.*

Yes, we have two variants specifically blended for curly and coily hair, depending on conditioning need.

Our light conditioning formula contains grapeseed oil to condition and enhance softness without adding excess weight to the hair.

Our rich conditioning formula contains more intensely nourishing ingredients like castor seed oil for deeper conditioning for soft and shiny styles.

Yes, Dyson Chitosan™ Pre-style cream and Post-style serum are engineered for all hair types and styles.

Your Pre-style cream should be based on your natural hair type, not the end style you're looking to achieve. You can use the same Pre-style cream to prime each time you style from wet, no matter what end style you're hoping to achieve.

 Our Post-style serum is designed for use after styling and can be used on all your favorite styles. How you apply the Post-style serum may vary slightly based on the styles you’re looking to achieve.

Our Pre-style cream has been engineered to prime your hair before drying and styling wet hair for touchable, 2x longer hold,* with a lightweight natural feel. We have formulated four variants for different hair types and conditioning preferences. 

Dyson Chitosan™ Pre-style cream should be applied to damp, towel-dried hair, before drying and styling.

Each formula contains the same level of our hero ingredient, chitosan, to create flexible hold in your hair.

In addition to chitosan, each variant has been precisely blended with different levels of other key ingredients - including emollients, conditioners, and emulsifiers - to suit different hair shapes and textures.

Our light conditioning formulas use grapeseed oil to nourish and enhance softness and hold, without adding excess weight to the hair.

Our rich conditioning formulas use more intensely nourishing ingredients, such as castor seed oil, to condition for soft, long-lasting styles on hair that needs more intense hair nourishment.

Choosing the right Pre-style cream variant for your hair comes down to two key factors and is based on your natural hair shape and texture, rather than the end style you're looking to achieve.

First, determine your hair shape. Our Pre-style cream is tailored to two groups of hair shapes: straight to wavy, and curly to coily. To find which applies to you, imagine your hair has been washed and left to air-dry. What shape do the majority of the strands take?

Second, decide your conditioning preference. If your hair strands are finer, or your overall hair density thinner, choose a light conditioning formula. If your hair is thicker, in strand diameter and/or density, or is more dry or damaged, you may prefer a rich conditioning formula.

The amount of Pre-style cream that’s right for you will vary depending on factors such as your hair length, density, thickness and condition.

Less is more with our Pre-style cream. We recommend starting with 2-5 pumps, building as needed for your hair.
