Hair, skin and breast changes
Thinner hair, itchy skin and sore breasts rarely make the headlines about perimenopause, but they're some of the changes women notice first.
The short answer: estrogen affects your skin, hair and breast tissue. As it swings and then falls in perimenopause, many women notice thinning hair, dry or itchy skin and sore breasts. These changes are common and usually harmless, but low iron and thyroid problems can cause similar changes, and any new breast lump should be checked.
Thinning hair
Estrogen helps keep hair in its growing phase. As levels fall, the balance tips towards the effects of androgens, the hormones women also make in smaller amounts. The result is often a gradual thinning across the top of the head, a wider part, and sometimes a few more coarse hairs on the chin.
Before blaming hormones, it's worth checking for other common causes at this age: low iron from heavy periods, an underactive or overactive thyroid, crash dieting, and a stressful stretch a few months earlier, which can trigger shedding.
What helps: correcting any iron or thyroid problem first. Topical minoxidil has the most evidence for female-pattern thinning, and low-dose oral minoxidil is increasingly used off-label. Hormone therapy may help some women, though it isn't prescribed for hair alone.
Dry, itchy or crawling skin
Estrogen supports collagen and helps skin hold on to water. After it falls, skin tends to become drier, thinner and more easily irritated, and the loss of collagen is fastest in the first years after menopause. Some women get widespread itching, and some feel an odd crawling or tingling sensation.
- Use a gentle, fragrance-free cleanser and lukewarm rather than hot water
- Apply a thick moisturizer within a few minutes of bathing
- Wear sunscreen every day, since sun damage speeds collagen loss
- Let us check for other causes of itching, such as thyroid, liver or kidney problems, if it's persistent
Hormone therapy can help skin stay thicker and better hydrated, which some women count as a real benefit when they use it for other symptoms. Hormone therapy
Small changes add up. We'll look at all of them.

Sore, tender breasts
This one surprises women who expect symptoms of low estrogen. In perimenopause, some cycles produce a surge of estrogen with little progesterone to balance it, which can leave breasts swollen and tender, often worse before a period. It usually eases after menopause.
A supportive, well-fitted bra and an anti-inflammatory medicine on bad days help many women. If you're on hormone therapy and your breasts are sore, a dose adjustment often fixes it.
Always get checked for: a new lump, skin dimpling or redness, a nipple that turns inward, or nipple discharge, especially if it's bloody or from one side. Keep up with your screening mammograms as well.
Other skin changes you might notice
Adult acne can flare in perimenopause as the hormone balance shifts. Rosacea and flushing can worsen alongside hot flashes. Nails may become more brittle. All of these respond to treatment, and we can manage most of them as part of your primary care, referring to dermatology when it helps.

Hair, skin and breast questions
Does perimenopause cause hair loss?
It can. Falling estrogen can make hair thinner, especially across the top of the head, and some women notice more hair on the chin. Low iron, thyroid problems and stress are also common causes at this age, so they're worth checking.
Why is my skin so itchy in perimenopause?
Estrogen helps skin hold moisture and make collagen. As it falls, skin gets drier and thinner, which can cause itching. Some women also feel a crawling or tingling sensation. Gentle cleansers, a good moisturizer after bathing and treating the underlying hormone change usually help.
Are sore breasts a sign of perimenopause?
Often, yes. Breast tenderness in perimenopause usually comes from cycles with high estrogen and little progesterone. It tends to ease after menopause. A new lump, skin change or nipple discharge should always be checked, whatever your age.
Does hormone therapy help skin and hair?
Hormone therapy may help skin stay thicker and better hydrated, and some women notice their hair improves. It isn't prescribed for skin or hair alone, but it can be a welcome side benefit when it's used for other symptoms.
What treatments help thinning hair in menopause?
Topical minoxidil is the most established option. Low-dose oral minoxidil is also used off-label. Correcting low iron or a thyroid problem, and treating the hormone changes themselves, can help too.
