The Dyson Supersonic hair dryer has revolutionized the haircare industry with its innovative technology and sleek design. One of its touted features is its “cold shot” function, designed to set hairstyles and provide a blast of cool air. However, many users wonder just how cold this “cold air” truly is. Does it deliver a genuinely chilling experience, or is it merely lukewarm air masquerading as cold? This article delves into the reality of the Dyson Supersonic’s cold air function, exploring its purpose, effectiveness, and how it compares to other hair dryers on the market.
Understanding the Cold Shot Function
The cold shot button on a hair dryer serves a crucial purpose in the styling process. Heat is used to mold and shape the hair, making it pliable and receptive to styling. Once the desired style is achieved, a blast of cold air is applied to rapidly cool the hair. This rapid cooling helps to “set” the style, closing the hair cuticle and locking the shape in place. As a result, the hairstyle becomes more durable, resistant to humidity, and retains its shape for a longer period. Without this cold air finish, the hair is more likely to revert to its natural state, resulting in a style that quickly loses its definition and hold.
The Dyson Supersonic’s cold shot function is designed to perform this very task. It aims to provide a quick and effective way to set hairstyles, contributing to the overall longevity and quality of the finished look.
The Perception of Cold: Is it Truly Cold?
The perception of cold is subjective and depends on several factors, including ambient temperature, individual sensitivity, and the temperature difference between the air and the skin. What feels cold to one person may feel merely cool to another.
When it comes to the Dyson Supersonic’s cold shot, the air emitted is not ice-cold. Instead, it is unheated air that is drawn into the dryer and expelled through the nozzle. This means its temperature is largely dependent on the surrounding room temperature. In a warm environment, the “cold” air may feel more like lukewarm air. However, in a cooler environment, it will feel significantly colder.
The key is to understand that the Dyson’s cold shot isn’t designed to produce artificially chilled air. Its function is to provide a rapid temperature change compared to the hot air used during styling. This temperature contrast is what helps to set the hair.
Dyson’s Technology: Temperature Control
One of the defining features of the Dyson Supersonic is its intelligent heat control. The dryer uses a microprocessor to regulate the temperature of the airflow, preventing it from reaching extreme levels that could damage the hair. This same temperature control system also plays a role in the cold shot function.
While the cold shot doesn’t actively chill the air, the intelligent heat control ensures that the airflow is genuinely unheated. This means that the air is as close to ambient temperature as possible, maximizing the temperature difference between the hot and cold settings. This precise temperature control is crucial for achieving the desired styling results without compromising hair health.
Comparing Dyson to Other Hair Dryers
Many hair dryers on the market offer a cold shot function, but their effectiveness can vary. Some dryers simply reduce the heat output to a low setting, which may still emit warm air. Others may have a more effective cold shot function that delivers genuinely cool air.
The Dyson Supersonic stands out due to its consistent and precise temperature control. While other dryers may produce inconsistent cold air, the Dyson ensures that the cold shot is always unheated. This reliability makes it a more effective tool for setting hairstyles and achieving long-lasting results.
Furthermore, the Dyson’s powerful airflow also contributes to the effectiveness of its cold shot. The strong airflow helps to rapidly cool the hair, accelerating the setting process and maximizing the hold of the hairstyle.
Optimizing the Cold Shot Experience
To get the most out of the Dyson Supersonic’s cold shot function, consider the following tips:
- Use in a Cool Environment: If possible, use the dryer in a cooler room to maximize the temperature difference between the hot and cold settings.
- Apply Thoroughly: Ensure that the cold air is applied evenly to the entire hairstyle, focusing on the areas that need the most hold.
- Hold for a Few Seconds: Hold the cold shot button for a few seconds on each section of hair to allow the hair to cool completely.
- Use with Styling Products: Combine the cold shot with styling products, such as hairspray or mousse, to further enhance the hold and longevity of the hairstyle.
Real User Experiences and Reviews
Online reviews and user testimonials offer valuable insights into the real-world performance of the Dyson Supersonic’s cold shot function. Many users praise its effectiveness in setting hairstyles and reducing frizz. They appreciate the consistent temperature and powerful airflow, which contribute to a smooth and polished finish.
However, some users have noted that the cold air is not as cold as they expected. This is often due to the ambient temperature of the room. It’s important to remember that the cold shot is not designed to produce artificially chilled air, but rather to provide a rapid temperature change compared to the hot setting.
Overall, the majority of users find the Dyson Supersonic’s cold shot function to be a valuable tool for achieving professional-quality hairstyles at home.
The Verdict: Is Dyson’s Cold Air Effective?
While the Dyson Supersonic’s cold shot may not deliver an ice-cold blast of air, it is undoubtedly effective in setting hairstyles and improving their longevity. Its consistent temperature control, powerful airflow, and intelligent design make it a valuable tool for anyone looking to achieve salon-worthy results at home. The “coldness” is relative, but the impact on hair styling is undeniable.
Wrapping It Up: Final Thoughts on the Dyson Supersonic’s Cold Air
Ultimately, the Dyson Supersonic’s cold air function is a testament to the brand’s commitment to innovation and performance. It’s not about the absolute temperature of the air, but rather the intelligent application of temperature change to achieve superior styling results. This nuanced approach sets the Dyson Supersonic apart from other hair dryers on the market and solidifies its position as a leader in the haircare industry.
Answers to Your Questions
Q1: Is the Dyson cold shot actually cold, or just cool?
A: The Dyson Supersonic’s cold shot emits unheated air, meaning its temperature is close to the ambient room temperature. It’s not artificially chilled, so whether it feels cold depends on how warm the room is. In a cooler room, it will feel colder than in a warm room.
Q2: How does the Dyson cold shot help with styling my hair?
A: The cold shot rapidly cools the hair after it has been styled with heat. This rapid cooling sets the hairstyle, closing the hair cuticle and locking the shape in place. This makes the style more durable and resistant to humidity.
Q3: Can I use the cold shot with styling products?
A: Yes, combining the cold shot with styling products such as hairspray or mousse can further enhance the hold and longevity of the hairstyle. Apply the product before using the cold shot to set the style.
