A new approach to haircare

Product design Industrial design IOT

We had the opportunity to work for SEB brand group. They needed our help to expand their product range of hairstyling devices. Our goal was to enable customers considering hairstyle and hair care in a brand new way. I worked in collaboration with an ux/ui designer, Anne Lefèvre. This choice was relevant to compose a team with all skills needed to create a connected product.

Field Study

Users

After some researches on the current market and technologies, we decided to create a form to analyse and understand the needs of potential costumers and collect some data.In total, 138 people filled it in, 107 women and 31 men. At the end of this questionnaire we asked people if they would accept a meeting. We interviewed four women in their own home about their own hair experience, the different hair problems they have, the tools and beauty products they used. Each time we interviewed, we used open questions to let them talk freely. Then, they showed us how they used their tools such as the hair straighteners or the hairdryer. We filmed everything for analysis.

Weak Points

Hair protection: Our users had issues with existing hairstyling tools. For example, on a hair straightener there is nothing on the machine that clearly explain when you will burn your hair , and everything depends on your type of hair. Then, they have another problem with the texture of their hair. Customers expressed this lack of information: they do not realise how their hair is, and how to better take care of it. They need a visualisation of this kind of data, in real time . Rapidity: In each interview, the rapidity was a clear necessity. They want to be fast every morning before going to work. Trend: These women are not following every trends, but they often want to change their haircut or find a new hairstyle, learning how to style it properly them hair. Budget: Never forgetting their budget, they agree on paying for a good product which can help them everyday, but not if it is too expensive.

Professional Hairstyle

Then, we interviewed a broad range of hairdressers. We wanted to know what exactly customers are looking for when they go to the hair-stylist.

The answer was in 3 points: advice & learning, confidence and trend/change. After all this analysis we found our way and followed this line:

Reinforce the beauty process by defining purposes

Concept

Then we began to propose a concept based on users we met, and developed a product called “Her”. It was a connected object which uses your data to create the perfect schedule for your hair with your favorite tools and daily requirements. It analyses your hair with the sound ( and other sensors as accelerometer, gyroscope) and determines what they need to reach your goal the quickest. At the beginning, we were focused on a ring that you could plug on different hair tools. I tried to do some quick and dirty mock ups in aluminum to see the ergonomy and the way to used it, it was completely unusable.

Test with the aluminium ring

I continued to search another shape. After sketches and plaster mockup, I finally found a shape which mold perfectly the hand and the everyday hair tools.

I began to 3D-model with solidworks and 3D-print it to check the ergonomy of the product. I repeated it until finding the good shape and size. After that, I created the hair-dryer for the new product range in 3D. I used keyshot for the 3D rendering.

We developed the mobile interface for our project, first with wireframes, then on Sketch App. We worked hard on the structure to have an intuitive interface and a useful connection between the object and the application.

HER App / principle

I printed in 3D our little brush and the Hairdryer. I created the electronic part of the little product and inserted it in each model. After some coats of paint, we had a functional prototype.

I met a second time one of our users Laure, to let her try the project and have a user feedback. She was interested in the project and gave me feedbacks to improve the product and the application. I made a final video with her.

Conclusion

Final project

Final Mock up

For our final presentation we put everything together and showed the concept to SEB brand group. They gave an enthusiastic welcome to our project and told us that they will continue to develop the product in this direction.
