Why Your Hair Changes During Menopause

If you've noticed your hair thinning, changing texture, or shedding more than usual as you move through your 40s and 50s, you're not imagining it. And you're definitely not alone.

52% of postmenopausal women experience significant hair thinning. That's more than half of us. Yet this is rarely discussed in doctor's offices, salons, or even among friends.

The primary reason? Estrogen. During our reproductive years, estrogen helps keep hair in its active growth phase (called anagen) for longer. It also promotes blood flow to the scalp and supports the production of natural oils that keep hair hydrated and shiny.

When estrogen levels begin to decline during perimenopause—which can start as early as your late 30s—the growth phase shortens. Hair grows slower, thinner, and falls out more quickly. At the same time, the relative increase in androgens (which were always present, just balanced by estrogen) can cause follicle miniaturization, especially at the crown and temples.

But here's the important part: understanding why this happens is the first step toward addressing it. A Board Certified Trichologist can evaluate your specific pattern of changes and create a protocol that addresses the root causes—not just the symptoms.
