Menopause Hair and Scalp: Shedding, Dryness and a Scalp That Suddenly Hurts

What is actually happening

Oestrogen keeps hair in its growth phase longer. As oestrogen falls and the androgen-to-oestrogen ratio shifts:

• The growth phase shortens, so hairs are shed sooner and reach shorter lengths.
• Follicles miniaturise in androgen-sensitive areas of the scalp — the crown and the part line, producing the diffuse widening most women notice first.
• Individual strands become finer, so volume drops even before shedding increases.
• Sebum production falls, so hair is drier, duller and more prone to breakage.
• Texture changes — straight hair can turn wavy or coarse.

The pattern matters: female pattern hair loss widens the part and thins the crown while preserving the frontal hairline. A receding hairline, or round smooth bald patches, is something different and should be seen by a doctor.

The scalp part nobody mentions

Scalp skin is skin, and it goes through the same barrier changes as your face — fewer lipids, less water retention, more sensitivity. Many women in perimenopause develop:

• A dry, tight, sometimes flaky scalp
• Trichodynia — genuine scalp pain or tenderness, often described as sore hair roots, particularly where hair is tied back
• Itching without visible dandruff
• New sensitivity to hair dye and shampoo that was fine for decades

That last one is worth taking seriously. Para-phenylenediamine in permanent hair dye is a significant contact allergen, and sensitisation can develop at any point regardless of how long you have used it. Reactions can be severe. Patch test before every colour, properly — 48 hours, behind the ear — not just the first time.

Shampoo running over your face and eyelids is also a common and rarely suspected cause of facial and eyelid dermatitis. This is where a skincare brand can actually help you, and where I would concentrate: the hairline, behind the ears and the back of the neck, where shampoo residue and dye contact collect and where dermatitis shows up first. The Gluten-Free Vegan Calming Face Cream is fragrance-free and rich enough for those margins.

What has evidence

1. Topical minoxidil. The best-evidenced over-the-counter option for female pattern hair loss. It works while you use it and reverses if you stop. Expect an initial increase in shedding in the first weeks — that is follicles resetting, and it is the point at which most people give up. Give it six months.
2. Treating the underlying cause, if there is one — see the blood tests below.
3. Prescription options. Spironolactone and other anti-androgens are used off-label, and there are newer options. Worth a dermatology referral rather than years of supplements.
4. Reducing mechanical damage. Tight ponytails, heat styling and aggressive brushing cause breakage that compounds thinning. Traction alopecia from years of tight styles is real and eventually permanent.
5. Hormone therapy, which some women find helps. Not a licensed treatment for hair loss, but relevant if you are considering it anyway.

Most hair supplements have weak evidence unless you are actually deficient. Biotin is the exception with reasonable data — and note that biotin interferes with several laboratory tests, including thyroid function and troponin, so tell your doctor if you take it.

Blood tests worth asking for

Hair loss is one of the areas where a treatable cause is genuinely common, and worth excluding before accepting it as hormonal:

• Ferritin. Iron deficiency is a leading cause of hair shedding in women and is extremely common with heavy perimenopausal bleeding. Ferritin can be low with a normal full blood count — ask for it specifically.
• Thyroid function. Both over and under cause hair loss.
• Vitamin D and B12.
• Coeliac serology, if there are other suggestive symptoms — malabsorption causes hair loss, and celiac clusters with thyroid disease.
• Androgens, if there is rapid onset with acne and marked facial hair growth.

Also worth knowing: telogen effluvium — diffuse shedding two to four months after a stressor such as illness, surgery, crash dieting or severe stress — is common, dramatic, and usually self-resolving. If your shedding started suddenly and you can identify an event three months earlier, that is likely what it is.

Practical daily changes

• Wash less frequently, with a gentle sulfate-free, fragrance-free shampoo
• Condition mid-length to ends, not the scalp
• Lukewarm water — hot water strips the scalp as it does the face
• Air dry where possible; heat protectant when you do not
• Loose styles, and vary where you part
• Silk pillowcase to reduce friction breakage
• Sunscreen or a hat on a widening part — exposed scalp burns, and it is a common site for skin cancers that get missed
• Adequate protein and iron in your diet

Frequently Asked Questions

Why is my hair thinning and my chin hair getting coarser at the same time?

One hormonal shift, two opposite effects. As oestrogen falls the androgen-to-oestrogen ratio rises — and scalp follicles miniaturise in response to androgens while facial follicles are stimulated by them. Same signal, opposite outcomes.

Is menopausal hair loss permanent?

Miniaturisation can be slowed and partly reversed if treated early, which is the argument for not waiting. Follicles that have fully miniaturised over many years are harder to recover. Get the treatable causes excluded first — iron deficiency and thyroid disease are common and correctable.

Why is my scalp suddenly sore or tender?

Trichodynia — scalp pain, often described as sore hair roots — is a recognised and under-discussed perimenopausal symptom, related to the same barrier and sensitivity changes happening on your face. Loosening tied-back styles usually helps.

Can I still dye my hair?

Usually yes, but patch test before every colour, not just the first. Para-phenylenediamine is a significant contact allergen and sensitisation can develop after decades of uneventful use. Reactions can be severe, and the 48-hour test behind the ear genuinely matters.
