The short answer
- Common: many people notice heavy shedding in the months after giving birth.
- Usually temporary: dermatology guidance describes this shedding as typically settling with time.1
- Get it checked if shedding continues well beyond the expected window, if you see patches or widening part lines, or if you have other symptoms.
- Measure it: a baseline makes it easier to tell recovery from ongoing thinning.
Why hair sheds after childbirth
Hair grows in cycles. During pregnancy, hormonal changes can keep more hairs in the growing phase. After delivery, many of those hairs move into the resting phase together and then shed. This pattern of diffuse shedding after a trigger is called telogen effluvium.2
The shedding usually appears a few months after the trigger rather than right away, which is why it can feel sudden.1,2
What is usually expected
The American Academy of Dermatology describes postpartum shedding as excessive shedding that is not true hair loss, and notes that most people see hair return to its usual fullness over the following months.1 Lighter-weight styling, gentle handling, and avoiding tight hairstyles can make the period easier.
When to get it checked
- Shedding that continues well past your baby’s first year, or keeps getting worse.
- A widening part or more scalp visible on top, which can point to pattern thinning rather than shedding.
- Patches, scaling, redness, or pain on the scalp.
- Fatigue, feeling cold, or other symptoms that could suggest thyroid or iron problems.3
Childbirth can also unmask hereditary thinning that was already developing.3 A clinician can help separate the two.
Why a baseline helps
When you are shedding, it is hard to judge from the mirror whether hair is recovering. At MOHR, the in-person Hair Assessment records a baseline with HairMetrix scalp imaging and standardized photography, so change can be compared under similar conditions. If shedding looks expected and self-limiting, the right plan may simply be to wait and recheck.
Treatment while breastfeeding
Some hair-loss medications are not appropriate during pregnancy or breastfeeding. Any treatment decision should be made with a clinician who knows your full history. For broader context, see our guide to women’s hair thinning in NYC.

Frequently asked questions
Is postpartum hair loss permanent?
Postpartum shedding is usually temporary. If shedding continues well beyond the expected window or you see a widening part, an evaluation can check for other causes.
When does postpartum shedding start?
It usually appears a few months after delivery rather than immediately.
Can I start HairCheck while breastfeeding?
Yes. HairCheck is a photo review, not a treatment. Any treatment decision is made in person with a clinician who knows your history.
Should I get my thyroid or iron checked?
Discuss it with your clinician, especially if you have symptoms such as fatigue. Thyroid and iron problems are recognized causes of hair loss.
Not sure if it is shedding or thinning?
Start with a complimentary HairCheck, or book the in-person MOHR Hair Assessment for HairMetrix imaging and a baseline. The $495 $299 fee is credited toward your first treatment if you proceed.
