Wear your hair in a certain fashion and it can make you feel like a million bucks – but style your locks in the wrong way, and you could be looking years older, a hairstylist to stars like Kate Hudson and Gal Gadot has warned.
Speaking to the Daily Mail, London-based Gustav Fouché shared his guide to styling your hair in each decade – and the common mistakes that make people appear much older.
In your 40s, he suggested always making sure to complement your face shape. He urged women of this age to ditch relying heavily on extensions or going too bright in colour.
Meanwhile, those in their 60s should avoid opting for overly dark, solid colours, like Courteney Cox, because this can be quite harsh against older skin, according to the celebrity hairstylist.
‘In this decade, your hair should feel expensive, well cared for and full of personality. It should never be frizzy, dull or overly set,’ explained Gustav.
Are you now worried your hair is making you look older? Read the hairstylist’s ultimate guide below…

In your 20s
Gustav said: ‘Your 20s are about freedom, experimentation and enjoying your natural beauty. At this age, hair should feel fun, relaxed and expressive, rather than overly polished.
‘Someone who captures this perfectly is Elle Fanning, 27. Her hair often allows her natural tone to show through at the root, keeping the colour soft and believable.
‘She avoids anything too harsh or over-processed, which keeps her look fresh and youthful.
‘Whether she is wearing her hair long and effortless or experimenting with a softer bob, it always feels age-appropriate and joyful.
‘In your 20s, there is nothing to disguise, hair should feel honest, light-hearted and something you genuinely enjoy wearing.’

‘By your 30s, many women start to refine their identity and personal style. Hair often becomes more considered, but it’s still important not to lose softness,’ said the stylist.
‘Jennifer Lawrence, 35, is a great example of balance. She suits both lighter and darker shades but avoids extremes, keeping the colour soft and flattering against her skin.
‘When she wears a fringe, it’s gentle and sits around the brow, never too blunt or severe. This kind of subtlety enhances features rather than overpowering them.
‘Some more experimental looks, like very short or choppy fringes or overly warm blondes, can sometimes appear harsher at this stage.
‘For example, Kristen Stewart, 35, often leans into a punk-inspired aesthetic, which can look striking, but softer tones or slightly more polished finishes can be more universally flattering and timeless.
‘The key in your 30s is knowing who you are, and letting your hair reflect that with confidence and ease.’

Gustav said: ‘In your 40s, it’s so important to understand your face shape and your skin tone. Someone who gets this absolutely right is Reese Witherspoon.
‘She has a heart-shaped face and knows exactly which hairstyles work best to enhance her features while softening any imperfections.
‘That’s why, when we see her on the red carpet, she always looks effortlessly gorgeous and her colouring is consistently spot on.
‘You’ll notice she very rarely goes fully blonde. This is something many women in their 40s do, lighter and lighter blonde to camouflage white hair, but understanding what your skin tone can truly handle is key.
‘Reese manages this beautifully. Although she’s a natural blonde, she keeps the blonde brighter around the face while ensuring it never goes all the way to the root.
‘There’s always a subtle shadow at the root, which connects seamlessly with her eyebrows and skin tone. The result is natural, flattering, and incredibly well balanced, and she does it exceptionally well.

In your 50s

‘By your 50s, confidence is high and personal style is well established. Hair should feel groomed but never stiff or overworked,’ said the hairstylist.
‘A standout example of getting it just right is Jennifer Aniston. She maintains a medium brunette base with soft honey highlights around the face, which brightens her complexion without pushing her too blonde.
‘Her styling always feels relaxed and natural, polished, but never over-styled. In your 50s, hair should move well, fall naturally, and feel youthful without trying too hard.’
But the expert also warned: ‘A block fringe can visually shorten the face and emphasise jawline softening after 50.’

Gustav said: ‘Your 60s are about embracing who you are and enjoying your style with freedom. Hair should feel modern, glossy and full of life.
‘Length becomes particularly important here. Hair that’s very long can sometimes drag the face down or create heaviness.
For example, Brooke Shields has beautiful hair, but when worn very long it can appear flat at the crown and heavy at the ends.
A slightly shorter length, for example around the collarbone, paired with a soft, sweeping fringe could add lift and freshness.
A brilliant example of vibrant, age-positive hair is Julianne Moore. She embraces her natural copper tone, which enhances her skin beautifully.
‘Her hair always looks glossy, healthy and modern, proof that shine and condition are the ultimate markers of youthful hair at any age.
‘One thing to be mindful of is overly dark, solid colour. Courteney Cox often wears a very deep brunette that, while glossy, can appear quite strong against maturer skin.
‘Introducing subtle variation or warmth can soften the overall look and be more flattering.

‘In your 60s, hair should feel expensive, well cared for and full of personality. It should never be frizzy, dull or overly set.
‘No matter your age, the most youthful hairstyle is one that feels authentic, soft and well looked after. Trends come and go, but healthy hair, flattering colour and confidence never go out of style.’
