Study: Postpartum Alopecia & Hair Shedding After Birth
What the research says about when it starts, why it happens, and how to support regrowth
It’s one of the most common (and unexpected) parts of new parenthood: hair loss after birth.
A landmark study published in Archives of Dermatology looked at how postpartum hair shedding really works. The findings help us understand that this isn’t a flaw or failure. It’s a natural part of your body’s reset.
Here’s what the study revealed, and what it means for your recovery.
Study Overview
Study Title: Study of Postpartum Alopecia
Authors: Bencel L. Schiff, A.B. Kern
Published In: Archives of Dermatology, 1963

Key Findings

88.7% of participants with postpartum shedding began losing hair between 8–16 weeks after giving birth.

The front of the scalp (especially the hairline) was the most commonly affected area (59.1% of cases).

Genetics did not play a major role. Most people experienced shedding whether or not it ran in the family.
What This Means for You
Postpartum hair loss is common, expected, and temporary.
✔ Shedding typically begins 2–4 months postpartum
✔ The hairline may thin, but it will regrow
✔ Your family history doesn’t determine whether it happens. It’s just part of the process
The best thing you can do?
Focus on supporting your body’s recovery. Gently, consistently, and with compassion.
Understanding Postpartum Hair Loss: Why It Happens
During pregnancy, your estrogen levels rise, which keeps your hair in a prolonged growth phase.
That’s why your hair may have looked fuller and thicker.
But after birth:
🔽 Estrogen drops rapidly.
🔽 Your hair shifts into the resting (telogen) phase all at once.
🔽 Shedding peaks around 3–6 months postpartum.
🔽 Regrowth begins naturally. If your body has the nutrients it needs.
This is not permanent hair loss. It’s a reset. And with the right support, regrowth can feel smoother and stronger.
