Which hair dryer is the most energy efficient?

• Dry hair efficiently to help reduce running time.
• Offer multiple airflow and temperature settings.
• Allow users to tailor drying and styling to their hair type.
• Combine drying and styling functions in a single device.
• Support everyday styling routines without relying on excessive heat.

For people exploring alternatives to traditional hair dryers, devices that combine drying and styling in one routine can also be worth considering. The Dyson Airwrap Co-anda2x™ multi-styler and dryer is designed to bring together drying and styling within a single device, with attachments for drying, curling, smoothing, volumising and creating straighter styles.

Quick answer: what determines how much energy a hair dryer uses?

The energy efficiency of a hair dryer depends on more than wattage alone. In most cases, overall energy use is influenced by a combination of power consumption, drying time, airflow performance and styling efficiency.
 

Hair dryers that help users achieve their desired result efficiently may use less energy during a styling session than devices that require longer drying and styling times.

• The wattage of the device.
• How long the dryer is used.
• Airflow performance.
• Heat and airflow settings.
• Hair length, density and texture.
• Whether separate styling tools are needed after drying.

For many people, the most energy-conscious approach is to look for a hair dryer or styling device that supports an efficient routine from start to finish, rather than focusing on power ratings alone.
 

This guide explains the key factors that influence hair dryer energy efficiency, what to look for when comparing models, and how to make a more informed purchasing decision.

When evaluating an energy efficient hair dryer, focus on how efficiently it turns electrical energy into effective drying and styling. A hair dryer that dries hair quickly and allows you to achieve your desired style in fewer steps may ultimately use less energy during each styling routine.

Look beyond wattage

Many people assume that a lower-wattage hair dryer automatically uses less energy. In reality, efficiency is often influenced by:

• Drying speed.
• Airflow performance.
• Heat settings.
• Styling time.
• Hair length and thickness.
• How often the device is used.
   

For example:

• A lower-powered dryer may require a longer drying session.
• A more powerful dryer may complete drying more quickly.
• Total energy consumption depends on both power usage and running time.

This is why wattage alone should not determine which hair dryer you buy.

Assess airflow performance

Airflow plays a crucial role in drying hair.
 

An effective airflow system can help remove moisture efficiently, reducing the amount of time required for drying and styling.

• Airflow control.
• Multiple airflow settings.
• Targeted airflow attachments.
• Drying functions that suit your hair type.

Good airflow can help you achieve your desired style more efficiently without relying solely on higher heat settings.

Check for adjustable settings

Different hair types require different drying approaches.

• Multiple heat settings.
• Adjustable airflow settings.
• Cool shot functionality.
• Settings suitable for different styling tasks.

This flexibility allows you to tailor your routine to your hair's specific needs rather than always using maximum heat or airflow.

Consider drying and styling together

1. A hair dryer.
2. A styling brush.
3. A curling tool or straightener.

Each device consumes additional energy.
 

Some modern styling devices combine multiple functions into a single routine, reducing the need to switch between several appliances during styling.
 

If you regularly dry and style your hair, consolidating steps may create a more streamlined routine.

Think about your hair type

The most suitable energy efficient hair dryer for one person may not be the best choice for another.
 

Different hair types have different requirements.

Fine hair

• Lower heat settings.
• Controlled airflow.
• Lightweight styling routines.

Thick hair

• Greater airflow.
• Efficient drying attachments.
• More targeted styling tools.

Curly and coily hair

• Diffuser attachments.
• Controlled drying.
• Styling routines that help maintain natural definition.

Choosing a device suited to your hair type can help make styling sessions more efficient overall.

An energy efficient hair dryer generally combines effective drying with thoughtful energy use.

Faster drying can reduce overall energy consumption

Energy use is not simply about how much power a device draws at a given moment.

• How long the device is used.
• How many styling steps are required.
• How frequently styling tools are used.

If hair can be dried and prepared for styling more quickly, overall energy consumption per styling session may be reduced.

Efficient styling routines matter

Your styling habits contribute significantly to energy use.

• Removing excess moisture with a towel first.
• Detangling before drying.
• Using appropriate heat settings.
• Working in sections.
• Avoiding repeated styling passes.

Small improvements throughout the process can make a meaningful difference over time.

The role of attachments

Attachments can help focus airflow where it is needed.

• Concentrators.
• Diffusers.
• Smoothing attachments.
• Volumising brushes.

Using the right attachment for the desired result may help create a more efficient styling experience and potentially shorten styling time.

Many people want to know exactly how much electricity a hair dryer uses.
 

The calculation is relatively straightforward: Energy consumed = Power (kW) × Time used (hours)
 

For example, a hair dryer used for a short period each day may consume less electricity overall than a lower-powered model that requires significantly longer drying sessions.

• Hair length.
• Hair density.
• Styling goals.
• Environmental conditions.
• Drying technique.

For this reason, practical efficiency should be considered alongside power ratings.

If you're not planning to replace your hair dryer immediately, there are several ways to improve efficiency.

Remove excess water before drying

• Gently squeeze excess moisture from the hair.
• Use a microfibre towel where possible.
• Avoid vigorous rubbing.

The less water remaining in the hair, the less drying work is required.

Choose the right heat setting

The highest heat setting isn't always necessary.

• Starting with moderate settings.
• Adjusting according to hair type.
• Using cooler settings for finishing.

Style strategically

• Sectioning hair.
• Drying methodically.
• Avoiding repeated passes over the same area.
• Planning your desired finished look before you begin.

Maintain your device

Follow manufacturer guidance for:

• Filter cleaning.
• Attachment care.
• Storage.

A well-maintained appliance can support consistent airflow and performance.

How styling routines can influence energy use

When choosing an energy efficient hair dryer, it can be useful to look beyond power consumption alone. The way you dry and style your hair can also influence the overall energy used during a styling session.
 

Many people use several tools to achieve their desired look, moving from a hair dryer to additional styling devices. Others may prefer a styling routine that combines multiple steps within a single device.
 

The Dyson Airwrap Co-anda2x™ multi-styler and dryer is designed for a range of styling routines, with attachments for drying, curling, smoothing, volumising and creating straighter styles. It can also connect to the MyDyson™ app, allowing you to personalise your styling experience.
 

When researching an energy efficient hair dryer, consider not only the wattage of a device, but also how it fits into your overall routine. A styling tool that supports multiple styling needs may help simplify the journey from wet hair to a finished style, making it easier to create the look you want with a single styling system.
