Is the weight of the hair dryer the first thing you want to know when choosing a new hair dryer?
Is the number of watts the second thing you want to know?
What if I tell you that neither of these things really matter for a hair dryer’s ergonomics or drying ability?
When I say ‘pistol hair dryer’, do you know what I’m referring to, that it’s shaped like a pistol?
Ok, so let’s start with ergonomics.
Studies show that it is the positioning of the arm whilst blow drying that puts stress on the joints and muscles.
With pistol-shaped hair dryers, you are forced to lift your elbow out from the body whilst drying the customer’s hair. Hairdressers often have to extend their elbows as much as 60° out from the side of the body. As well as this, the head is often leaning forwards, and nerves and tendons get moved around in the shoulder. You have likely felt pain in the upper trapezius
Many hairdressers try to hold the end of the hair dryer in order to get a lower arm position, however this causes an imbalance in the dryer that stretches the wrist, and can cause wrist and underarm pain.
Hair dryers today are very light, and that is partially due to DC motors and brushless motors
This might lead you to think that lighter hair dryers make things easier
Sadly, it’s not that simple. If you have a light hair dryer that needs longer to dry hair, it can be as harmful as using a heavier, more powerful, hair dryer. Because it’s the amount of time you spend with the elbow out to the side that causes harm to the joints
Regularly using the trapezius muscles for more than 4 minutes at a time will increase neck and shoulder pain over time ref: Scand J Work Environ Health 2013;39(4)
17.3% of hairdressers’ sick leave is caused by muscle- and bone pain (ref: Stami faktabok 2018)
The Dual Air dryer allows you to work in a natural working position, with less elevated arm and significantly less activity in upper trapezius muscle.
