The timeline

Stage	When (typically)	What's happening
Duration	Often 1–6 months after weaning	HealthLink BC: people often lose hair for 1 to 6 months after childbirth or after they stop breastfeeding. [HealthLink]
Context	Breastfeeding can extend shedding	Johns Hopkins: women who breastfeed might notice a longer period of shedding as hormonal changes continue. [Johns]

Postpartum shed vs weaning shed

	After birth	After weaning
Best-sourced timing	Starts ~2 months, peaks ~4 months [American]	1–6 months of loss [HealthLink]
Evidence quality	Well described by AAD	Few sources; no peak week published

No source we found gives a peak week for weaning shed, so the calculator only shows the 1–6 month range.

Commonly normal

Diffuse shedding in the months after weaning
Hair that had felt fuller while breastfeeding thinning back

Frequently asked questions

How long does hair loss after stopping breastfeeding last?

HealthLink BC says people often lose hair for 1 to 6 months after they stop breastfeeding.

Why am I losing hair after weaning?

Hormone levels shift again when breastfeeding ends; Johns Hopkins notes hormonal changes continue throughout breastfeeding.

Is weaning hair loss the same as postpartum hair loss?

Both are hormone-related shedding. Postpartum shedding is better documented (peak about four months after birth per AAD).
