While some people keep their auburn locks into their fifties, others see grey strands creeping in when they've barely finished celebrating their 21st birthday.
But what makes some people get grey hair way earlier than others?
According to research by hair care brand Charles Worthington, your natural hair colour, lifestyle and job could all affect when your grey hairs begin to show.
The study polled 2,000 women in order to find out when we're losing our youthful colour and how we feel about it when we do.
While the study concluded that the average age for a woman to go grey is 33, it found redheads lose their colour at 30, brunettes at 32 and blondes at 35.
For one in 10 women, those first grey hairs appear by the time they reach 21-years-old, while one in four women find their first grey by the age of 25.
If you're below 30 and already discovering steely strands, it could be a sign you're not getting enough sleep. Fatigue can cause the follicle ageing process to accelerate, making your younger colour disappear more quickly.
Your occupation could also be the key - the researchers found call centre workers were more likely to go grey in their mid-thirties while women working in entertainment start to spot greys at the age of 27.
The refreshing news to come out of the study is that, while some women still hate their grey hairs, 10% said covering up greys wasn't on their radar as they like to think of their new colour as a sign of "wisdom and experience."
