Postpartum Hair Loss: Biology Behind the Shedding

Understand the hormonal rollercoaster that drives postpartum hair shedding — and recovery.

Source: Journal of Obstetric EndocrinologyPublished on: September 12, 2025
Abstract in Plain English

Many new mothers experience temporary shedding after childbirth. Researchers analyzed hormonal transitions that cause hair follicles to enter resting phase, then recover over time.

Key Findings
  • Estrogen and progesterone drops trigger synchronized follicle shedding.
  • 85% of women reported visible thinning 2–4 months postpartum.
  • Hair regrowth typically resumes by 12 months.
  • Breastfeeding status showed minor impact on shedding duration.
Why It Matters

Understanding this biological rhythm reassures patients that postpartum hair loss is temporary, reducing anxiety and unnecessary interventions.

Study Limitations

Self-report bias may inflate prevalence; hormonal levels measured only twice.
