Perimenopause can bring noticeable changes to your skin, including the skin on your scalp. Hormonal shifts can cause the skin to lose moisture, making the scalp dry and the hair brittle. Dandruff, a common scalp condition, occurs when dry skin flakes off and causes itching.
Itchiness and flaky scalp are often linked to a decline in estrogen, which plays a role in collagen production and skin hydration. Restoring estrogen to premenopausal levels can help improve scalp moisture and reduce dandruff.
