Tell us about your first job in beauty?

My first job in beauty was as an Assistant Manager in the cosmetics hall at UK department store Harrods after completing two years on its Graduate Training Scheme.

I quickly became obsessed with the wonderful characters who worked for the various brands – from La Prairie and Estée Lauder, to Sisley and La Mer – and their extraordinary knowledge of their customer base.

It made me realise how powerful those connections brands have with customers in-store can really shape a person’s experience of the company.

What was a lesson you learned early in your career?

Is there someone who has helped you climb the ladder or provided some key advice?

One of my first bosses at Harrods, Marigay McKee, who was Head of the Beauty Department, was instrumental in helping me climb the ladder, and I am forever grateful for everything that I learned from her.

In later years, industry legends such as Tracey Woodward and Hilary Dart provided key advice when I was starting my own consultancy, telling me: “Do not do anything that will damage your relationships, and do not do things for a quick win.”
