How hair changes with age & what you can do about it

Hair changes as we get older, and it can creep up gradually, so one day you might look in the mirror and be surprised at how dry, frizzy or limp your hair is now.
Since peri-menopause mine has remained as fine as it’s always been, and become straighter, and greyer. It used to be slightly greasy, but now it’s dry and fluffy after washing unless I use oil or leave-in conditioner. I like Bumble & Bumble Hairdresser’s Invisible Oil Heat UV Protective Hair Primer Leave-In Conditioner (£16, 60ml) and Living Proof No Frizz Vanishing Oil (£35, 50ml).
Keeping grey great
Around 50% of us are 50% grey by the age of 50, caused by the slowdown in melanin production. We are big fans of grey hair at That’s Not My Age but some days it can look dull and flat, and yellow tones, caused by mineral build-up and sun exposure, can give a ‘brassy’ appearance. Fortunately, there are loads of purple-toned shampoos and conditioners to offset this. Alyson recommends the violet range at White Hot Hair, and Debra Hepburn loves the Oribe Bright Blonde range as ‘it’s not as too harsh and purple-y.’
A word of warning: some purple products can stain (clothes, towels, grout…!)

Thinning hair and hair loss
‘Thinning hair’ is caused by declining oestrogen, and doesn’t mean, as many people think, that you have fewer hairs, but that each hair is finer, so hair seems to lack volume and body overall. Check you’re not deficient in iron or vitamin D – both are vital for hair growth.
Shampoo formulated for fine hair will help. Olaplex is highly recommended by TNMA readers – and Philip Kingsley’s Body Building Weightless Shampoo (250ml, £28) contains keratin (the protein in your hair) and is a best-seller.
Hair loss means shedding more than the average 50 to 100 hairs a day and products containing minoxidil (like these) work for many. Alpecin Caffeine Shampoo has good reviews (250m, £6.65)
Boost the volume
Use your hairdryer to add root lift and body. The official Philip Kingsley advice is, at the end of drying, to bend over and let your hair hang down towards the floor. Gently brush or comb it in this direction with the hairdryer following behind. When your hair is dry, style as normal.
The best formulation for a styling product for thinning hair is mousse: light and aerated, it lifts and holds without weighing hair down. Philip Kingsley Volumising Froth Lift Mousse (150ml, £25) has provitamin B5 to plump up the hair shaft and add moisture.
Dry shampoos and volumising sprays are a quick fix. Launched over 40 years ago, Batiste Dry Shampoo Original’s primary purpose is to absorb grease, but its rice starch adds bulk (200ml, £3.25). And if you’re grey it doesn’t show when you don’t brush it out properly.

Stay sun safe
Like your skin, your hair and scalp need SPF. UV rays cause colour fading, damage hair’s structure and make it dryer, weaker and more porous. Grey hair is even more at risk because it lacks protective melanin. Be a little gentler on your hair in the sun. Brush or comb less often, avoid heated styling tools and use a cooler hairdryer setting. Move your parting, if possible, to avoid repeated sun exposure along one line.
Might sound obvious but the simplest way to protect hair, especially between 11am and 3pm when the sun is strongest, is a hat, which also shades face, ears and neck. Or add a scarf: a triangular one tied at the nape of the neck, a wide bandeau, or pirate-style, knotted at the back of your head. (We like Seasalt Cornwall’s cotton Sailor Squares).
Protect your scalp from sunburn along the parting or where hair has become thinner, ideally with transparent spray formulations. Lightweight and water-resistant, Aveda Sun Care Protective Hair Veil (£32, 100ml) has natural-derived UVA and UVB filters, with green tea and vitamin E. La Roche Posay Anthelios Anti-Shine Sun Protection Face Mist (£14.80, 75ml) offers broad-spectrum protection and a dry finish with no white marks.
If you prefer a sleek, wet-look finish, comb through a creamy option. The Kérastase Soleil range protects against UV, salt and chlorine. As with all suncare, re-apply after swimming or towel-drying.
Ways with water
Saltwater and swimming pools make your hair dry and brittle. The salt in seawater draws water out of the hair, and pools’ water-purifying chemicals such as chlorine and bromine can roughen the hair by lifting its outer scales.
Protect hair by soaking it with fresh water 15-minutes before swimming, in the shower, or with a bottle of water. That way, it won’t absorb chlorinated or saltwater. Rinse immediately after your swim, then shampoo as soon as possible.
Developed for the first US Olympic synchronised swimming team, Philip Kingsley Swimcap mask, applied to wet hair, protects your hair from chlorine, saltwater and UV rays. (£25, 100ml).
Treat your hair to a conditioning treatment, such as Maria Nila Colour Refresh hair mask (£24.50, 300ml) comes in several shades, including my favourite, Pearl Silver.
Try Philip Kingsley Elasticizer, a pre-shampoo deep-conditioning treatment developed for Audrey Hepburn in 1974, to hydrate, add shine and volume, and reduce breakage (£25, 75ml).
To boost shine, mix equal parts of cider vinegar and water, pour on to hair, massage in, then rinse. Using cool water for your final rinse also helps smooth hair, giving a shinier finish.

My hair turned curly when I stopped having regular periods in perimenopause. The photos of me as a child show straight hair and through my 20s and 30s it had only a very gentle wave at the ends, but since age 40 it has been full on curls. It was quite startling, but I have read of other people having hair transformations due to hormonal changes (e.g. during pregnancy). I am now corkscrew-curly and menopausal at 44. I quite like the curls, but might have preferred the thinner straight hair that I expected to develop. My hair has always been very thick and I was never able to get the pixie cuts I wanted because I simply had far too much hair. No hope of pixie cuts now!
