Objective: Research shows that physical appearance is one of the key drivers of personal well-being. An improvement in facial attractiveness is associated with positive changes in emotional and social dimensions of one’s life. Hair colouring is an important means of cosmetic improvement in women and men. However, no research has been carried out so far to assess its impact on quality of life (QoL) using an instrument validated for cosmetic products and physical appearance. The main objective of this study was to assess the impact on QoL of two hair colouring products (Excellence® by L’Oréal Paris and Olia® by Garnier) using the BeautyQoL® questionnaire, specially designed and internationally validated for use in cosmetology.

Methods: A randomized control study has been carried out involving a total of 240 adult women (45-70 years old) assigned in two groups "Excellence" and "Olia". The BeautyQoL® questionnaire was administered in order to assess the impact of the two hair colouring treatments on QoL across five well-being dimensions: social life, self-confidence, mood, energy, and attractiveness. At the end of the study, subjective satisfaction questionnaires were used to assess the perceived performance and tolerability for each product, as well as interest in future use.

Results: The results of this study suggest that the QoL was improved in subjects using hair colouring products based on the overall and dimension-specific BeautyQoL® scores at the end of the experiment. The results of the satisfaction questionnaire were also conclusive, confirming the subjects’ good tolerability and overall satisfaction of the tested hair colouring products.

Conclusion: Hair colouring is used by millions of women and men who wish to look good, enhance their appearance, self-confidence and their overall attractiveness. For the first time, using the internationally validated BeautyQoL® questionnaire developed to specifically assess cosmetic products and physical appearance, the results of this study firmly establish that hair colouring contributes to improving the overall and dimension-specific QoL scores, and the well-being of users worldwide.
