Perimenopause and hair loss: what to know

The change may be gradual, with more hair noticed in a brush, shower drain, or on clothing. Some people notice reduced fullness at the part or temples, while others mainly notice a change in hair texture. Hair concerns can occur alongside other menopause-transition symptoms such as irregular periods, hot flushes, or night sweats.

During perimenopause, ovarian hormone levels fluctuate rather than changing in a single step. Those shifts can alter the hair-growth cycle and may make individual strands feel finer or the scalp look less covered. Age-related changes, inherited pattern hair loss, thyroid problems, low iron stores, illness, major stress, restrictive eating, and some medicines can produce similar shedding.

Hair loss is not a reliable way to identify perimenopause on its own. A clinician may ask about the timing of shedding, menstrual changes, recent illness, diet, medicines, family pattern, and scalp symptoms. Examination and selected blood tests can help separate hormone-related change from another treatable cause.

Handle hair gently: use a wide-toothed comb, avoid tight styles that pull at the roots, and limit frequent high heat or harsh chemical processing. Choose enough protein and a varied diet rather than starting high-dose supplements without advice; excess amounts of some nutrients can worsen hair problems.

Keep a simple record of when shedding began, whether the part is widening, and any changes in periods or medicines. Arrange a medical review if thinning continues, because treatment depends on the cause. Do not stop a prescribed medicine without speaking with the prescriber.

Book a clinical assessment for sudden or rapidly worsening loss, clearly defined bald patches, broken hairs, scalp pain, marked redness, scaling, sores, or intense itching. Seek prompt advice if hair shedding comes with pronounced tiredness, breathlessness, unexplained weight change, or very heavy periods, as these may point to an underlying problem such as iron deficiency or thyroid disease.

A clinician can also assess new facial hair growth, severe acne, or other signs of androgen change. These findings do not establish a diagnosis, but they make a broader assessment useful.

Ask: What pattern of hair loss do you see? Could my periods, recent illness, diet, medicines, iron stores, or thyroid be contributing? Do I need an examination or blood tests? Which treatments fit my health history, and how long should I use them before reviewing the result?
