Hair changes are one of the more distressing menopausal symptoms women raise, partly because they're visible and partly because they're often dismissed. If your hair has become thinner, shed more than usual, or changed texture in your 40s or 50s, you're not imagining it. The relationship between hormones and hair is real, and the patterns are well-described.
Key facts at a glance
- Up to 40 percent of women experience hair thinning around menopause.
- Two patterns are common: female pattern hair loss (gradual thinning across the crown) and telogen effluvium (sudden, diffuse shedding after a trigger).
- Iron, ferritin, vitamin D and thyroid function are worth checking, particularly if shedding is sudden.
- Gentle hair care, protein and a varied diet support the basics.
- If shedding is sudden, severe or includes the scalp showing through, see your GP.
Why hair changes in menopause
Hair growth follows a cycle: a growing phase (anagen), a brief transition phase, and a resting and shedding phase (telogen). At any given time, most of your hair is in the growing phase. Oestrogen helps prolong the growing phase, so when oestrogen declines, the proportion of hair in the resting phase rises. The result is hair that grows less long, sheds more, and feels thinner overall.
The relationship between oestrogen and androgens (testosterone-family hormones) also matters. Even though women's androgen levels don't rise during menopause, the falling oestrogen changes the relative balance. For women with a genetic susceptibility, that shift can trigger or accelerate female pattern hair loss, particularly across the crown and along the part.
The two common patterns
Female pattern hair loss
This is the most common form of hair loss in midlife women. The pattern is gradual thinning across the crown and along the part, with the hairline at the temples and front usually preserved. The hairs themselves often become finer rather than the scalp showing a clear bald patch. There's almost always a genetic component, often visible in mothers, aunts or sisters.
Telogen effluvium
Telogen effluvium is a diffuse, sudden increase in shedding that typically starts two to three months after a trigger. Triggers can include illness, surgery, significant weight loss, severe stress, iron deficiency, low ferritin, thyroid disturbance, or starting or stopping certain medicines. Unlike female pattern hair loss, telogen effluvium is usually reversible once the trigger is identified and addressed. Recovery takes months, not weeks.
Both patterns can happen at the same time. A woman with female pattern hair loss may notice a sudden worsening triggered by another factor, which makes the underlying genetic pattern more apparent.
What's worth checking with your GP
Before anything else, blood tests are useful for identifying treatable contributors:
- Iron studies, including ferritin (low ferritin is a common, often-missed cause of hair shedding)
- Thyroid function (TSH and T4)
- Vitamin D
- Vitamin B12
- Full blood count
Your GP may also examine your scalp and look at the pattern of thinning. In some cases, a referral to a dermatologist is helpful, particularly if there's scarring, redness or any sign the hair loss is progressing rapidly.
What actually helps
Address the medical contributors first
If iron, thyroid or vitamin D are low, correcting them often makes a meaningful difference. This is the lowest-cost, highest-yield step and worth doing before anything else.
Adequate protein
Hair is made of protein. Severe protein restriction or rapid weight loss can trigger or worsen shedding. Aim for around 1.0 to 1.2 g per kg of body weight per day, distributed across meals.
Gentle hair care
Heat styling, tight hairstyles, harsh chemical treatments and aggressive brushing can all contribute to hair appearing more fragile. Reducing these doesn't reverse genetic hair loss, but it helps the hair you have look its best. Use a gentle shampoo, avoid daily heat styling, and brush wet hair with care.
Topical and prescription options
Several topical and prescription options exist for female pattern hair loss, with varying levels of evidence. These are discussed individually with a GP or dermatologist, because the right choice depends on the pattern, your medical history and what's realistic for you to use long-term. Hair-loss treatments typically need to be continued indefinitely to maintain effect.
Wigs, toppers and styling
These are legitimate options, not last resorts. Many women find that practical adjustments to styling, parting, or using a hair topper makes a meaningful difference to how they feel day to day. There's no medal for soldiering through unhappily.
What's less proven
The supplement market for hair is enormous and the evidence is mixed. A genuine deficiency in iron, vitamin D or another nutrient should be discussed with your GP, but adding multiple high-dose supplements without a clear deficiency rarely produces dramatic results and can sometimes cause its own problems. The same goes for elaborate scalp products, expensive shampoos, or anything promising regrowth on a short timeline. Be cautious of claims that sound too good.
When to see your GP
It's worth booking an appointment if:
- Hair shedding has been heavy for more than two months
- You can see scalp where you couldn't before
- The hair loss is patchy rather than diffuse
- There's redness, itch or scaling on the scalp
- You haven't had iron studies, thyroid or vitamin D checked recently
- The change is affecting how you feel about yourself
Hair loss is sometimes treated as cosmetic, but it can be a real source of distress and a marker of something else going on. A GP visit is the right starting point.
A reasonable perspective
Most menopausal hair changes can be managed, even if they can't always be reversed completely. The combination of identifying medical contributors, supporting hair with sensible care, and considering treatment options where appropriate produces good outcomes for most women. The first step is a conversation with someone who'll take it seriously.
