Your hair at 50: what’s normal

You’re doing your hair in the hallway mirror, and the light falls right on the top of your head. Your part looks wider. The grey has reached your temples. The hair tie goes round your ponytail one more time, or the clippers pass over less hair than they used to. At 50, the question nearly always comes up: is this just age, or am I losing my hair?

Often it’s a bit of both, and most of the time there’s nothing to worry about. A few signs are still worth an appointment. Here’s how to tell them apart.

At 50, pattern hair loss is the rule rather than the exception

In men, the figures are clear. The European guideline on androgenetic alopecia, the medical name for common pattern hair loss, puts it at 50 to 60% of men by 50, and about 80% by 70 and beyond¹. The American Academy of Dermatology (AAD) puts it another way: by 50, more than half of white men have a visible sign of pattern hair loss². It is less common and less marked in men of Asian, Native American or African American descent¹.

So if your temples are receding or your crown is thinning, you’re in line with most men your age. That doesn’t mean there’s nothing to do: pattern hair loss progresses slowly, and you can keep track of it.

In women, it’s less common but far from rare. DermNet, the New Zealand dermatology reference, says about 40% of women show signs of it by 50³. It usually starts in the 40s, 50s or 60s, and is often first noticed as a thinner ponytail⁴. It doesn’t clear the front: it thins the top of the head and widens the part, usually leaving the hairline in place¹. It isn’t the only cause of hair loss in women: we go through the most common causes in another article.

What age changes for everyone

Alongside pattern hair loss, there’s plain ageing. The AAD sums it up in one sentence: with age, most people notice some hair loss because hair growth slows⁵. In women, the hairline also naturally starts to recede⁵.

So a slight recession of the hairline in a woman of 50 isn’t abnormal in itself. In female pattern hair loss, it’s mainly the top of the head that thins, and the AAD notes that hair near the temples may recede too⁴.

The NHS reminds us that most hair loss is either temporary or a normal part of getting older⁶. And at any age, we lose 50 to 100 hairs a day without noticing⁶. Finding hair in your brush is no cause for alarm.

Grey hair: the rule of 50 doesn’t hold

You may know the saying: by 50, half of people have half their hair grey. A team of researchers checked it in 4,192 healthy volunteers, men and women, from several regions of the world. Assessors compared each person’s hair colour against standard swatches⁷.

Between 45 and 65, 74% of participants had grey hair, covering on average 27% of their hair. Men had significantly more than women. At the same age, people of Asian or African descent had less than people of European descent⁷.

One limit: these were volunteers, not a random sample, and colour was judged by eye by experts rather than measured by a device⁷. The message is still clear: going grey is normal, but the pace varies a lot from one person to another, and most 50-year-olds are nowhere near half.

What about the menopause?

Female pattern hair loss is more common after the menopause, which suggests hormones play a part⁴. DermNet links this rise to falling oestrogen, while noting that its exact role is uncertain³.

A study from Bangkok gives a sense of scale. Of 178 postmenopausal women aged 50 to 65, photographed from six angles and examined with a dermatoscope (a lit magnifier), 52.2% had female pattern hair loss⁸. In nearly three cases out of four (73.2%), it was at the first, mildest stage⁸. Once age and family history were taken into account, only being overweight remained linked to it⁸.

Limits: 178 women, a single team, and a Thai population, whereas female pattern hair loss is generally less common and starts later in Asian women than in Europe¹. The general point stands: after the menopause, some thinning is common, and usually mild.

What’s worth a doctor’s opinion

Normal doesn’t mean all hair loss is the same. Some signs fall outside ordinary ageing.

The third point deserves a closer look. It describes frontal fibrosing alopecia, which typically affects postmenopausal women over 50, though men can get it too¹⁰. It looks like the normal recession of the hairline, but the skin there becomes pale and shiny, with no visible follicle openings, and eyebrow loss often comes first¹⁰. It’s a scarring alopecia: hair doesn’t grow back unless it’s treated early¹⁰.

Hair loss that suddenly speeds up often has a specific cause: here are the causes checked first. The thyroid is one of them, and when it’s to blame, treating the condition can bring the hair back⁵. If a medicine is the cause, don’t stop it on your own: talk to the doctor who prescribed it first⁵.

And if pattern hair loss bothers you, your doctor can suggest a treatment. The AAD notes that results are better when treatment starts at the first signs⁴. To work out who to see, the signs that call for a doctor are covered here.

Seeing what really changes

At 50, hair changes slowly. From one week to the next, you see nothing. From one year to the next, you can’t quite remember how you looked. And the mirror doesn’t help: the light, the angle, wet hair or a different style throw everything off.

One photo a week, taken in the same conditions, settles it. With Calvap, your previous photo shows through as a transparent overlay so you can line up in the same spot, and your photos sit on a dated timeline. Aim at your part, crown, temples and hairline. Over the months, you see whether your part is really widening or it was just the light, and whether your hairline is moving a millimetre a year or much faster.

If you see a doctor, you show dated photos instead of an impression. Your photos stay on your phone.
