With the well-being of the worker in mind, this book sought to solve the problems of RSI caused by repetitive strain when hairdryers are used by beauty salon professionals. Through design, we realised the need to create a product that would help hairdressers perform their task. Once the information had been collected, in the form of a questionnaire to professionals in the field, in order to gather concrete data on the activity, it was realised that there was a need to make an ergonomic hairdryer that was lighter and produced less noise than those found on the market. In addition, one of the outstanding features of the result is its shape, which transformed the solution into an innovative product. The dryer also has an air conduction system in the solution and two removable tips that are used separately, one for a directional jet and the other for curly hair. In this way, the objectives set for the project were achieved.
