Postpartum Hair Loss Timeline, Causes, and Daily Care
Medically reviewed by Medical Advisory Board Last reviewed 2026-09-29
Changes in estrogen after childbirth cause temporary hair shedding that typically resolves within a year.
Postpartum hair loss occurs about three months after childbirth due to dropping estrogen levels. Shedding can last up to six months, and hair usually regains fullness by the child's first birthday. Learn what causes this shedding and when to speak with a healthcare provider.
Postpartum hair loss typically starts about three months after childbirth, can last up to six months, and hair usually regains its fullness by the time the child turns one. This temporary shedding happens because elevated estrogen drops after delivery, which prompts retained hairs to enter a resting phase. At The Metabolic Journal, we summarize published clinical sources on hormone shifts and recovery so readers have clear information on postpartum changes.
According to the Cleveland Clinic, postpartum hair loss is very common, and most people notice some hair loss after childbirth. This shedding is clinically categorized as a form of telogen effluvium triggered by bodily changes following pregnancy.

Estrogen changes during and after pregnancy cause postpartum hair loss. In the last trimester of pregnancy, estrogen levels rise, which prevents typical daily shedding. Following childbirth, estrogen levels drop, and those retained hairs enter the resting phase before falling out.
Typically, people shed up to 100 hairs per day under ordinary conditions. With postpartum hair loss, people lose more than 100 hairs daily as hairs enter the resting phase. A healthcare provider diagnoses postpartum hair loss from increased shedding and a recent pregnancy, and published clinical sources describe no specific test for the condition.
Postpartum Hair Loss Timeline
Postpartum hair loss occurs about three months after childbirth and can last up to six months. Cleveland Clinic notes that hair should regain its fullness by the time the child turns one.
While daily shedding remains above the normal baseline of up to 100 hairs per day during this window, the shedding decreases as hair cycles normalize.
What You Can Do While It Grows Back
Cleveland Clinic states there is no treatment for postpartum hair loss and nothing that prevents it.
Cleveland Clinic suggests five daily habits to help manage hair appearance while it regrows:
- Volumizing products
- Gentle hair care
- Lower heat settings
- Avoiding tight hairstyles
- A healthy diet
Ask a clinician which daily practices apply to your personal situation.
When It Might Not Be Postpartum Shedding
If shedding lasts more than six months, talk to your provider, since iron deficiency or thyroid disease may be responsible. While most people notice some hair loss after childbirth, shedding that extends beyond six months warrants clinical evaluation.
A provider can advise whether laboratory testing is appropriate for your symptoms, such as iron and ferritin testing or evaluating for hypothyroidism (see blood tests for hair loss). A healthcare professional can determine if an underlying nutritional or endocrine condition explains prolonged hair loss. This page is educational and not a substitute for a clinician's advice.
Where to Find Iron & Ferritin Test Kits
Many labs and direct-to-consumer services let you order a iron and ferritin test without a doctor's visit. If you'd rather compare kits yourself, here's where to start looking:
- At-home iron and ferritin test kits on Amazon — compare brands, prices, and Prime shipping.
