Hair and skin: what changes as estrogen falls?

Summary

Skin that dries out, thins and loses its elasticity; hair that thins, with the crown opening up; a few coarse hairs on the chin. These are the visible signs of menopause and a direct consequence of falling estrogen. Collagen decreases markedly in the first five years after menopause; hair follicles lose estrogen's protective effect. Part of aging is unavoidable, but part of it is manageable: sun protection, the right skin care, evidence-based treatments for hair loss, and screening for correctable causes (iron, thyroid). HRT is not started for skin or hair; but when it is taken for another reason, benefits may be seen in these areas too.

What is happening?

Skin: Estrogen supports collagen and elastin production, the skin's capacity to hold water, the working of the oil glands and wound healing. As it falls:

Collagen content drops; skin thins, lines deepen and sagging begins.

The skin barrier weakens; dryness, itching and sensitivity increase.

Wound healing slows; bruising happens more easily.

The accumulated effect of sun damage becomes visible in this period; menopause is when the damage shows, not its only cause.

Hair: Estrogen lengthens the growth phase of hair. As it falls and the effect of androgens (male hormones) becomes relatively more prominent:

Hair strands thin and there is diffuse thinning; opening up at the crown and the front-central area becomes noticeable (female pattern hair loss). The hairline is usually preserved.

The same androgen effect can produce coarse, dark hair growth on the chin and upper lip.

Iron deficiency, thyroid disease, rapid weight loss, severe stress and certain medicines are also common — and correctable — causes of hair loss in this period.

What do we know?

Collagen loss is rapid: A classic study showed that skin collagen in postmenopausal women fell by about 30% in the first five years after menopause, with the annual loss slowing thereafter; the loss ran in parallel with the decline in bone density ¹.

Estrogen affects the skin, but is not given for the skin: Improvements in skin thickness, collagen and moisture have been reported in women taking HRT; guidelines treat this not as an indication but as a possible side benefit of treatment given for vasomotor symptoms ² ⁴. Evidence for cosmetic products containing topical estrogen is limited and regulation varies.

Sun protection is the single most effective measure: Most of the visible signs of skin aging are due to ultraviolet damage; daily broad-spectrum protection is the anti-aging intervention with the strongest evidence. Retinoids (under medical supervision) increase collagen production ².

There is evidence-based treatment for female pattern hair loss: The European S3 guideline recommends topical minoxidil as first-line treatment in female pattern hair loss; the effect takes months to appear and use must be continued. Antiandrogen medicines are assessed by a dermatologist in selected cases ³.

Correctable causes should be screened first: Ferritin (iron stores), thyroid function and vitamin D are a standard part of assessing hair loss; menopausal hair loss should not be diagnosed until these have been excluded.

What does this give you?

What you can do for your skin today: Daily sunscreen; a gentle cleanser instead of soap; moisturizer straight after a shower; stopping smoking. It is a consistent routine, not an expensive product, that makes the difference.

For hair: When you notice hair loss, first ask your doctor to check iron, thyroid and vitamin D. If female pattern loss is suspected, there are dermatology assessment and evidence-based treatment options; "hair vitamin" supplements have not been shown to help where there is no deficiency.

Hair growth: A few coarse hairs are unremarkable in this period; a rapid, widespread increase does need assessment.

Set your expectations: The aim is not to get back the skin you had at 30, but to keep your skin healthy and comfortable. If itching and dryness are affecting your quality of life, that is a dermatological problem and it can be treated.

When to see a doctor?

Sudden, patchy hair loss; autoimmune causes should be assessed.

Hair loss together with acne, deepening of the voice, rapid and marked hair growth; hormonal assessment for androgen excess is needed.

A mole or skin lesion that is changing, bleeding or not healing; see a dermatologist without delay because of the risk of skin cancer.

Widespread, persistent itching and rash; systemic causes should be excluded.

These signs should be assessed without delay.
