What Do Scientists Say About Dual Air?
Research shows the negative impact of physical strain on hairdressers in their daily work. 3 out of 4 hairdressers say that they suffer from pain in the arms and shoulders (PDF).
Our goal at Dual Air is to improve hairdressers' lives by giving them the best tool to blow-dry hair in a continuous workflow, with minimal physical strain.
As hair drying accounts for around 30% of working hours for women’s hairdressers and about 20% for men's (Chen 2010), the non-dominant hand – the one holding the blow-dryer – is the one most likely to suffer. Dual Air has innovated a completely new and ergonomic design with a bi-directional airflow to combat physical repeated strain injuries.
This allows you to work in a comfortable position with low shoulders at all times. Reducing the time the elbow is raised above shoulder height reduces the risk of tendinitis by 20 percent.
- Using Dual Air reduces the time spent with the arm in high-strain positions by more than half.
- Using Dual Air was also shown to reduce activity in the mantle muscle.

The study also demonstrated the importance of simple training in how to use Dual Air. When holding Dual Air incorrectly, users don’t experience or achieve the benefits of our new design.
Dual Air customers have provided feedback that since they have switched to our product and used it over the past 1-2 years, their health issues related to shoulder strain have disappeared.
