Four months, third baby
I did it at four months postpartum with our third son — which, it turns out, is almost exactly when the shedding peaks. Dermatologists put the peak at three to five months after birth, and that is not a coincidence: the hair a birth switches off does not fall out immediately. It rests for roughly three months first. So the evidence of having a baby in February arrives in June, when you have stopped expecting anything else to happen to you.
The third time, you can see it coming
With the first, the shedding is alarming and you look it up at two in the morning. With the third, you recognise it, and you know it lasts under six months, and you know the hair comes back. What changes is that you stop waiting it out politely. By the third baby the calculation is not “will this get better” — it is “why am I spending an hour a day on this in the meantime.”
What is the “mom chop”?
A short cut taken shortly after having a baby — usually a bob or a lob, usually decided fast, often without warning anyone. The name is internet-issued rather than official, and it is used both affectionately and as a warning, which tells you most of what you need to know about how women’s haircuts get discussed.
Is it really about the hair loss?
Partly, and this is the part that gets misread as vanity. Long hair that is shedding does not look like shorter hair — it looks like less hair, because the length exaggerates the thinning at the temples and the hairline. Cutting it does not stop the shedding. It stops the shedding being the first thing you see.
The time argument is the real one
An hour of hair a day is a fiction once there is a baby in the house. Washing, drying, detangling, tying it back so it cannot be grabbed — that is the arithmetic. Short hair gives that hour back. Anyone treating the mom chop as a small tragedy has never tried to blow-dry long hair while a four-month-old is awake.
And the grabbing
A baby learning to grip reaches for the nearest available object, holds on, and does not understand the concept of letting go. Four months is exactly when that starts. Long hair is, from that angle, a handle — and so is a necklace, which is why those disappear in the same week. Our third has a grip like a fist closing on a door handle, and two older brothers who taught him nothing about restraint.
What he said
Hand over the mouth. Eyes the size of the plates. Then, once he had recovered the power of speech: chic, elegant, and it suits her. He has since said the same thing several times, unprompted, to other people, which from him is a standing ovation. I had braced for a pause and got a reaction I have watched back more than I will admit.
The part I did not expect
The comments did not want to talk about me. They wanted to talk about him — specifically that a husband reacting to his wife cutting her hair with delight rather than mourning is, in the words of roughly a hundred people, a green flag. The second thing they wanted was the name of the cut, and a lot of people guessed wrong. It is a layered bob, not a French bob. The difference is the whole point: a French bob is blunt — one clean line at the chin — and a blunt line is exactly what shows you how much hair is no longer there. Layers do the opposite. They break the weight up so the hair moves and stacks instead of hanging flat, which reads as more hair rather than less.
Should you do it?
Not my call, and worth saying plainly. Two things are true at once: the shedding is temporary and will grow back, so nothing has to be decided permanently; and there is no prize for keeping hair you are spending an hour a day on. If the shedding is heavy past a year, or comes with other symptoms, that is worth a doctor rather than a hairdresser.
Three reasons, ranked by how often they are the actual reason
| What it is | Does the haircut help? | |
|---|---|---|
| Time | An hour a day of washing and drying you no longer have | Yes — immediately |
| The grip | A baby who has discovered that hair is a handle | Yes |
| Shedding | Telogen effluvium, peaking a few months after birth | It hides it; it does not stop it |
Questions, answered
What is the difference between a layered bob and a French bob?
A French bob is blunt — cut to one clean line, usually at the chin, often with a fringe. A layered bob is cut at different lengths so the hair moves and holds volume. For postpartum shedding the layered version is more forgiving, because a blunt line makes thinning easier to see.
Why do women cut their hair short after having a baby?
Mainly for time and practicality. A shorter cut takes far less washing and drying, keeps hair out of a baby’s reach, and disguises postpartum shedding, which makes long hair look thinner than it is. The internet calls it the “mom chop.”
What is postpartum hair loss?
Postpartum hair loss is telogen effluvium — temporary diffuse shedding that happens when hormone levels drop back after childbirth. It usually becomes noticeable two to three months after delivery, lasts under six months, and fullness generally returns by around the child’s first birthday.
Does cutting your hair help with postpartum hair loss?
It does not stop the shedding, which is driven by the hair cycle rather than by length. What it does is make the thinning far less visible, and make daily hair care manageable while the shedding runs its course.
