Dame Helen Mirren, 70
Dame Helen Mirren became the face of L'Oreal in 2015. For the advertising campaign, she was given a stylish crop and treated to L'Oreal's new Excellence Age Perfect hair colour - which has since become her "new favourite product".
Speaking to the Mail Online, she said: "I have very fine hair so I've always been quite careful not to over-treat it. I don't normally colour or dye it, I like it to grow naturally, but this dye is fantastic. It really does what it says on the box, allows my hair to grow out naturally and is also very easy to use.
"Yes, I know it sounds like I'm saying it because of the advertising, but it's true! The brilliant thing is that it has layers of colour, it's not one colour that you then need to add highlights on top of."
Felicity Kendall, 69
If you want to live the good life and still look good, you need to exercise. That's the advice of actress Felicity Kendall. At the start of her stint on Strictly Come Dancing in 2010, she said: "I'm afraid the bad news is girls you've got to do the work in the gym. I haven't suddenly morphed into looking in the last week how I look now."
By the end of the BBC dancing competition, the actress had dropped almost two dress sizes and could fit into the size 26in waist jeans she wore during the 1970s show, The Good Life. You don't need a ballroom to get fit dancing, lose weight and tone up with a Strictly Come Dancersize DVD at home.
The 1960s model still looks fantastic – and credits her hairdresser for keeping her looking youthful.
Sharing her style and beauty secrets with the Mail Online, she said: "My natural hair colour is mousy brown. I love being blond. Often when I think I look dowdy, it's because I need the highlights doing. A trip to the hairdresser can be so transforming, not only for your mood but for its ability to add a level of elegance to the overall vision of a woman.
"For me, a fringe softens everything. It is also a clever tool to conceal lines. And a few layers around the face can also be flattering."
Jane Asher, 70
Actress Jane Asher always looks effortless stylish. If you're not sure what clothes suit you best, she has some good advice.
Speaking to Saga Magazine she said: "If you're unsure about a new outfit, take a 'selfie' in it – before you hand over your money – and show it to an honest friend for their opinion. Take a good hard look at the picture yourself, too. It's much easier to be objective about whether it suits you this way."
Joanna Lumley, 70
The Absolutely Fabulous actress, former model and tireless campaigner has some good advice about finding a style that suits you.
Speaking to Good Housekeeping magazine in 2014, she said: "I'm tall with broad shoulders and therefore I like clothes with a bit of a swagger – mannish clothes that you can wear with a lot of feminine, sweet tops. I put my own looks together – a favourite coat, a bit of vintage, a bit of high street."
If you're concerned about your weight, Joanna's advice is to go for a size up.
"Clothes that are too tight make you look bigger. If you've been trying to shed pounds and it doesn't go, buy the next size up. I never care what size my clothes are. I cut the labels out because they always scratch the back of my neck."
Dame Judi Dench, 81
Acclaimed actress and national treasure Dame Judi Dench has never worried about following fashion rules. Speaking to Stylist Magazine in 2015, she had some advice for anyone wanting to look good – wear what you feel good in.
"I have never worn anything fashionable for the whole of my life. I just wear old things which I like very much and have far too many of. Wear what you feel good in; it will look much chicer than wearing something fashionable that makes you feel ill-at-ease."
