Postpartum Hair Loss: Why It Happens and When It Stops

Postpartum hair loss is a common, temporary phase of heavy hair shedding that usually begins a couple of months after childbirth and peaks around four months after delivery. It happens because hormone levels fall after pregnancy, and the American Academy of Dermatology (AAD) notes that most women regain their normal fullness by their child’s first birthday, with many recovering sooner.

For new mothers in India, seeing clumps of hair in the comb or on the pillow can be alarming, especially when relatives have strong opinions on oils, diets and remedies. Here is what is actually happening and what helps.

Why does hair fall after pregnancy?

Each hair follicle goes through a growing phase and a resting phase, after which the hair is shed. During pregnancy, high oestrogen levels keep more hairs in the growing phase, which is why many women notice thicker hair while pregnant.

After delivery, oestrogen drops. The AAD explains that this fall in oestrogen pushes many hairs into the resting phase at the same time, and they are then shed together a few months later. Doctors call this telogen effluvium, meaning excessive hair shedding. DermNet lists childbirth as one of the typical triggers.

The AAD stresses that this is not true hair loss. The follicles are still working, and new hairs grow back.

What is the typical timeline?

Time after delivery	What usually happens
0 to 2 months	Hair often feels normal
Around 2 months	Shedding becomes noticeable
Around 4 months	Shedding usually peaks
6 to 12 months	Shedding slows and short new hairs appear, often along the hairline
By about 1 year	Most women regain normal fullness

The AAD notes that it is normal to shed between 50 and 100 hairs a day. During postpartum shedding, that number is much higher for a while.

Short new hairs sticking up around the forehead and temples are a good sign of regrowth, not breakage.

Can anything else make hair fall worse after delivery?

Yes. Several common postpartum issues can trigger or prolong shedding, and are worth checking if shedding is very heavy or long lasting:

• Iron deficiency. DermNet lists iron deficiency as a trigger of telogen effluvium, and the NHS notes that pregnancy and blood loss are common causes of iron deficiency anaemia. Heavy bleeding at delivery can add to this.
• Thyroid problems. DermNet includes both underactive and overactive thyroid among the causes of hair shedding. Thyroid changes can occur after pregnancy.
• Stress and lack of sleep, which are almost universal with a newborn.
• Rapid weight loss or a restrictive diet.
• Stopping the contraceptive pill, if you had been taking it.
• Illness with fever around or after delivery.

DermNet also notes that postpartum shedding can sometimes unmask or transition into female pattern hair loss in women who are already prone to it. Our article on hair fall in women explains how these conditions differ.

What can I do while my hair recovers?

There is no proven way to stop postpartum shedding, because it settles on its own. These steps can help your hair look fuller and reduce extra damage.

Hair care tips from dermatologists

The AAD suggests:

• Use a volumising shampoo, which can make hair look fuller.
• Avoid shampoos labelled conditioning shampoo, which can weigh hair down.
• Use a light conditioner made for fine hair, applied mainly to the ends rather than the scalp.
• Avoid heavy “intensive” conditioners.
• Consider a shorter haircut, which can make hair look fuller and is easier to manage with a baby.

Gentle habits

• Avoid tight buns, ponytails and braids that pull on the hairline.
• Comb gently with a wide toothed comb, starting at the ends.
• Limit heat styling, chemical straightening and colouring until shedding settles.
• If you like oiling your hair, gentle oiling is fine, but oils do not stop shedding. Wash it out properly to avoid scalp build up and dandruff.

Look after your overall health

• Eat regular, balanced meals with enough protein and iron rich foods.
• Continue any supplements your obstetrician has advised.
• Rest when you can, and accept help with night feeds if possible.

Avoid starting high dose supplements, such as biotin, without a reason. Supplements do not speed up recovery from postpartum shedding unless you are actually deficient.

A safety tip for babies: hair tourniquets

The AAD warns new mothers about hair tourniquets. A shed hair can occasionally wrap tightly around a baby’s toe, finger or other body part and cut off circulation. It is rare, but if your baby is crying unusually and you see a hair wrapped tightly around a digit, gently unwind or cut it, and seek medical help immediately if you cannot remove it.

What should I avoid?

• Medicated hair loss lotions or tablets without medical advice, especially while breastfeeding
• “Hair fall control” products that promise instant results
• Steroid creams or lotions on the scalp without a prescription
• Panic buying multiple serums and oils, which can irritate the scalp

When is it not just postpartum shedding?

See a dermatologist if:

• Shedding continues beyond about a year after delivery. The AAD says another cause may be involved.
• You notice a widening parting or thinning on the crown, which may be female pattern hair loss.
• You have round bald patches, which may be alopecia areata.
• Your scalp is itchy, scaly or red. See dandruff and seborrheic dermatitis.
• You feel very tired, breathless, cold or low, which may point to anaemia, thyroid problems or postnatal depression.

How is shedding different from true hair loss?

The AAD makes a useful distinction. Hair shedding (telogen effluvium) happens after a stressor such as childbirth, high fever, surgery, major stress or stopping birth control pills. The follicles keep working, and the shedding stops on its own as the body readjusts.

Hair loss, in contrast, happens when something stops the hair from growing. The AAD lists common causes as:

• Hereditary hair loss, such as female pattern hair loss
• The immune system attacking hair follicles, as in alopecia areata
• Some medicines and treatments
• Hairstyles that pull on the hair
• Harsh hair care products
• A compulsion to pull out one’s own hair

This is why hair that has not recovered after a year deserves a proper assessment rather than more oils and shampoos. The AAD also notes that if a stressor continues, shedding can last longer, so ongoing lack of sleep or illness can delay recovery.

When to see a dermatologist

Book an assessment if your hair has not returned to normal by your baby’s first birthday, if hair loss is patchy or concentrated on the parting or crown, or if you have other symptoms such as fatigue, weight change or irregular periods. A dermatologist may examine your scalp and suggest blood tests to check iron, thyroid and other levels.
