Why Is My Hair Falling Out?

Perimenopause hair loss has a few different patterns — and a few different fixes. This 8-question quiz points you to the most likely cause and the tests to ask for.

Most likely cause

Mixed picture — start with a blood panel

Your pattern doesn't fit one cause cleanly. A baseline blood panel will rule out the cheapest, most reversible causes first.

Tests to ask your GP

Ferritin, vitamin D, TSH, B12, full blood count.

Educational, not a diagnosis. Persistent shedding always deserves a GP review.

The 90-day hair recovery timeline

Hair grows in cycles. Whatever you do today shows up in your mirror in roughly three months. That means consistency beats intensity — and gives you a clear "is this working?" check-in at week 12.

  • Weeks 0–4: Shedding may continue or briefly worsen as old hairs are pushed out by new growth.
  • Weeks 4–12: Shedding slows. Baby hairs at the parting (1–3 cm) are the first visible win.
  • Months 3–6: Density increases noticeably. Most women see meaningful regrowth by month 6.

The fundamentals that move the needle

  1. Get ferritin above 70 ng/ml. Bigger lever than any shampoo.
  2. Eat 1.6–2.0 g protein / kg / day. Hair is keratin — built from the protein you ate yesterday.
  3. Stop fasted long workouts and aggressive deficits. Both spike cortisol and shed hair.
  4. Consider 5% minoxidil daily. The only over-the-counter regrower with strong evidence.
  5. Discuss HRT or spironolactone with your GP. Both address the root cause for the right candidate.
