Postpartum hair loss: why it happens and how to manage it

Many women notice significant hair loss a few weeks or months after childbirth. Although it can be alarming, this loss is, in the vast majority of cases, a natural and temporary phenomenon, directly linked to the hormonal changes of the postpartum period.

Why does hair fall out after childbirth?

During pregnancy, estrogen levels are very high. These hormones prolong the hair's growth phase (anagen phase), which reduces natural hair shedding. This is why hair often appears thicker, fuller, and shinier during this period.

After childbirth, estrogen levels drop rapidly. Hair that remained in the growth phase for several months then simultaneously enters the resting phase, followed by shedding. This phenomenon has a medical name: postpartum telogen effluvium.

When does shedding appear and how long does it last?

• It usually appears between 2 and 4 months after childbirth.
• It can last from several weeks to a few months.
• It often reaches its peak around the 4th or 5th month.
• It usually stabilizes within a year of birth.

It is not uncommon to lose more hair when washing or brushing during this period, especially at the temples and hairline.

Factors that can exacerbate hair loss

Hormonal imbalance is the primary cause of postpartum hair loss, but other factors often contribute.

Almost systematic realities of postpartum

These elements concern the vast majority of new mothers and cannot be avoided as such, but they partly explain the intensity of the hair loss:

• fatigue and lack of sleep due to broken nights;
• blood loss during childbirth;
• breastfeeding, which increases the body's nutritional needs;
• physical stress related to childbirth and recovery.

Additional factors specific to each situation

These do not concern all women, but they can further exacerbate hair loss when present—and it is on these that it is most useful to act:

• iron, zinc, protein, or vitamin D deficiencies;
• prolonged emotional stress;
• an undiagnosed postpartum thyroid disorder.

It is precisely because these latter factors are identifiable and correctable (via diet or medical follow-up) that they deserve special attention—unlike fatigue or breastfeeding, which are an integral part of this period.

Care to implement to support regrowth

The goal is not to completely prevent shedding—which is part of the normal physiological process—but to support regrowth and preserve the quality of the hair fiber during this transitional period.

1. Support the body from within

Hair health primarily depends on nutrient availability. It is advisable to ensure:

• sufficient protein intake (eggs, fish, meat, legumes);
• monitoring iron intake;
• maintaining good levels of zinc, vitamin D, and B vitamins;
• proper hydration.

In case of significant hair loss or persistent fatigue, a blood test may be relevant to check for any deficiency.

2. Adopt a gentle hair care routine

During this period, hair is often more fragile. It is preferable to prioritize:

• mild and non-aggressive shampoos; such as Maison Jearom shampoos, suitable from pregnancy, during postpartum and also afterwards, for the whole family.
• gentle detangling;
• loose hairstyles;
• limiting aggressive chemical treatments (bleaching, repeated straightening).

As a reminder, a mild shampoo is recognized by its formulation (mild surfactants, pH close to that of the scalp) rather than its "natural" character—the two notions do not systematically overlap.

3. Stimulate the scalp

Scalp massage can be beneficial for:

• promoting microcirculation;
• supporting the hair follicle environment;
• offering a moment of beneficial relaxation during an often intense period.

A few minutes a day are enough to reap the benefits.

4. Focus on fortifying treatments

Scalp-targeting treatments can support the regrowth phase:

• stimulating serums;
• fortifying lotions;
• recognized active ingredients such as caffeine, black garlic, niacinamide, or certain peptides.

These treatments do not prevent physiological hair loss, but they can help optimize regrowth conditions, just like our fortifying solid shampoo, with its ultra-gentle formula, concentrated in organic black garlic and vegetable charcoal.

When to consult a doctor?

Medical advice is recommended if:

• hair loss persists beyond 12 months;
• thinning areas appear;
• fatigue is significant;
• other symptoms are present (palpitations, unexplained weight loss, cycle disorders, etc.).

These signs may indicate an associated cause (deficiency, thyroid disorder) that warrants medical evaluation.

In summary

Postpartum is a period of major hormonal rebalancing. Hair loss that occurs a few months after childbirth is, most of the time, a sign of a return to the normal hair cycle rather than a definitive loss. With an adapted diet, gentle care, and targeted scalp support, regrowth gradually sets in, and hair usually regains its density over the months.

FAQ

How long does postpartum hair loss last? It usually appears between 2 and 4 months after childbirth, often peaks around the 4th or 5th month, and generally stabilizes within a year of birth.

Is postpartum hair loss normal? Yes. It is linked to the rapid drop in estrogen after childbirth and affects the majority of women. This phenomenon is called postpartum telogen effluvium.

Should I consult a doctor for postpartum hair loss? Medical advice is recommended if hair loss persists beyond 12 months, if thinning areas appear, or if other symptoms accompany it (significant fatigue, palpitations, cycle disorders).

What foods promote hair regrowth after childbirth? Proteins, iron, zinc, vitamin D, and B vitamins are particularly important for supporting hair health during this period.

Does scalp massage help limit postpartum hair loss? It does not stop physiological hair loss, but it promotes microcirculation and can support the hair follicle environment, in addition to offering a moment of relaxation.
