Under normal circumstances, we lose between 70 and 100 hairs a day — spread throughout the day in a way that goes almost unnoticed. After birth, this number can temporarily rise to between 200 and 300 hairs a day, with peaks during the most intense weeks. The shedding is distributed evenly across the scalp, without bald patches or thinning zones.
Hair loss typically begins 2–3 months after birth — not immediately — because this corresponds to the time follicles need to complete their resting phase before releasing the hair. Most new mothers see the shedding resolve within 6–12 months of giving birth.
If you are breastfeeding, the process may last a little longer, until weaning: prolactin maintains a certain hormonal balance that slows the return to normal, but it is not the primary cause.
When to see a doctor. If hair loss continues beyond 12 months, or is accompanied by unusual fatigue, weight changes, insomnia or mood swings, it is worth seeing an endocrinologist. In some cases, postpartum thyroiditis may be present — easily diagnosed with a simple blood test.
