Is it just shedding, or is something else going on?

Do this

1. 1

   Count back two to three months for a trigger: birth, fever, COVID, crash diet.

2. 2

   Photograph your part and crown every 4 weeks in the same light.

3. 3

   A part that keeps widening points to pattern loss underneath.

4. 4

   Keep tight styles off the hairline while hair regrows.

5. 5

   What the science points to: compare same-season photos (likelihood: medium).

6. 6

   See a doctor if shedding lasts past 8 months or your part widens.

The numbers behind it

For your hair

• New mothers

  Expect a shed from about 3 months after birth. A part that keeps widening afterwards deserves a doctor's look.

• After illness, surgery or dieting

  Shedding starts months after the event, so the cause can feel unrelated. Think back two to three months.

• Men

  A receding hairline or thinning crown is pattern loss, not shedding. See the hair loss guide.

• Why we suggest same-season photos

  Shedding peaked in summer in one study of 823 women, and a shed lags its trigger by months, so one bad month proves little.

Myths to ignore

• Myth Postpartum shedding is always just postpartum shedding.

  Truth Only 9.5% of 200 women had shedding alone. Most also had pattern loss that the shed brought into view.

• Myth Shedding that lasts for years is chronic telogen effluvium.

  Truth A review of 18 studies (1,628 cases) found no biopsy sign of a separate disease. Many cases look like early female pattern loss.

• Myth Hair loss after COVID means lasting damage.

  Truth Across 465 people, shedding began about 74 days after symptoms and most recovered.

Go deeper

• Postpartum hair lossMost women shed noticeably more hair in the months after giving birth, as the long growth phase of pregnancy ends and many hairs fall together; it usually peaks around 4 to 5 months and fades by about 8 months.
• Telogen effluviumA temporary burst of diffuse shedding that starts 2 to 3 months after a physical or emotional shock and usually settles within 6 months once the trigger is gone; it does not cause bald patches.
• The hair growth cycleEvery scalp follicle cycles through growth, shutdown, rest and release on its own clock, which explains normal shedding, seasonal changes, maximum length and how pattern hair loss works.
• When to see a dermatologistMost gradual thinning is pattern loss you can start treating yourself, but scarring signs, scalp symptoms, patches or sudden shedding should go to a clinician quickly because delay can cost permanent hair.
