Head Mistress of Lady Eleanor Holles School Heather Hanbury gave a clarion call for the importance of girls' only education as she addressed the Girls' Schools Association Annual Conference.
"Working like a woman is a great way to work and live," she said.
"No one should feel they have to ‘be like a man’ to succeed in life."
In her speech as GSA President, she said: "We all need to unleash our feminine side – it's proven that this is pivotal for society to become truly great.
"Much has been made of The Female Leadership advantage and quite rightly so."
Her comments generated headlines across the national press.
LEH's Head Girl team were also at the Conference and took part in a discussion forum with Conservative MP Dame Andrea Leadsom.
The four Sixth Formers quizzed her about a range of topical issues including the current cost of living crisis.
And two LEH alumnae, Abby Johnston and Charlotte Irving, gave an inspirational talk called An ExtraOARdinary Adventure.
They shared the lessons they had learned as they battled the elements, sea sickness, salt sores and sleep deprivation to smash the world Atlantic rowing record earlier this year.
The GSA Conference for Heads took place in London from the 21st to 22nd November.
