Rajni, the Chief Executive Officer of a multinational company, maintained a simple and elegant look. Now she wanted a change, so she decided to colour her hair in a vibrant colour. After reading the label carefully, she purchased a well-known hair colour of good quality. Before applying the colour, she read the instructions carefully. However, while applying the colour on her hair, she forgot the instructions and without testing it on a patch of her skin, she applied the colour. This led to an allergic reaction with redness and itching on her scalp, ears and neck. Identify the responsibility that was ignored by Rajni as a consumer while using the hair colour.
