It was a Tuesday morning, about ten weeks after my baby came home, when I noticed the drain. A nest of hair, more than seemed possible, coiled against the white porcelain. I stood there in my towel doing the math: if this much was coming out every shower, how much could possibly be left?

For me, the shedding had actually started earlier, during IVF, when the stimulation protocols sent my hormones into overdrive. People warned me about the injections, the bloating, the emotional rollercoaster of waiting to see if an embryo would take. Nobody mentioned the hair. Whether you got here through IVF, a vaginal birth, or a C-section, the hormonal trigger is the same, and so is that moment standing at the drain, wondering if this is normal or if something is wrong.

So I did what any of us do when something feels wrong: I went deep into the actual science. Here is what I found, and what genuinely helped.

Why This Is Happening: The Biology of Postpartum Shedding

Here is something about hair that nobody tells you: it is never all doing the same thing at the same time. Right now, on a normal day, about 85 to 90 percent of your hair is in the anagen phase, actively growing, sometimes for years. Another one to two percent is in catagen, a brief transition where growth pauses. And around ten to fifteen percent is in telogen, a resting phase, after which the strand sheds naturally in a process called exogen. Losing 70 to 150 hairs a day is completely normal. That is just the cycle.

During pregnancy, high estrogen essentially freezes more of your hair in the anagen phase. It delays the signal to transition into rest. So your hair stays in growth mode longer than it normally would. You may have noticed it felt thicker, more voluminous. That part was real. But it also meant that a larger-than-usual percentage of your strands were overdue for their natural shed.

Then you deliver. Estrogen and progesterone drop sharply, a hormonal cliff, and that drop triggers a cascade. Prolactin rises to initiate milk production. All those follicles that were overdue for rest get the signal simultaneously. They move into catagen, then telogen, then shed. This synchronized exit is called telogen effluvium, and it is exactly why the loss can feel so alarming: it is not a trickle, it is a wave. It typically peaks around two to three months postpartum.

Your follicles are not damaged. They are not going anywhere. This is a reset, not a loss. The same follicle that shed will re-enter anagen and grow again.

What You Can Actually Do About It

You cannot stop telogen effluvium. The hormonal shift is happening regardless. But you can support your follicles through the transition and reduce how intensely the shedding phase hits. Here is what I focused on, and what the science actually backs up.

Protect your sleep like it is medicine.

I know you have a newborn, and sleep feels like a cruel joke. But elevated cortisol accelerates follicle turnover, which compounds the shedding that is already happening hormonally. Even imperfect sleep matters: longer stretches when you can get them, naps you do not skip, help you actually ask for. Treat rest as part of the treatment plan.

Eat like your follicles are listening.

Hair follicles are metabolically active and sensitive to inflammation, so what you eat genuinely matters here. Colorful vegetables, berries, leafy greens, and adequate protein all help maintain the cellular environment follicles need to cycle back into growth. Keep up your prenatal vitamin or switch to a postnatal, especially if you are breastfeeding. Your body is still giving a lot.

Get your thyroid checked.

Postpartum thyroiditis affects up to ten percent of women in the first year after delivery and is frequently missed because its symptoms, including fatigue, hair loss, and mood changes, overlap with normal new-mom exhaustion. If your shedding feels excessive or prolonged past six months, ask your OB or midwife for a TSH panel at your postpartum visit. It is a simple blood test and worth ruling out.

On topical minoxidil: it is an option, with caveats.

There is evidence that topical minoxidil supports hair retention by increasing blood flow to the follicle and prolonging the anagen phase. I looked into it seriously, and ultimately held off while I was breastfeeding. Safety data during lactation is limited, and I was not comfortable with the uncertainty. If you are not nursing, or once you have weaned, it is worth a conversation with your provider.

Low-level laser therapy: the intervention I felt most confident in.

I started using LLLT on myself during the postpartum period after digging into the research. It uses wavelengths in the 630 to 680 nm range to act directly on the mitochondria of follicle cells, increasing cellular energy production, stimulating vasodilation, and encouraging blood flow and growth factors to the scalp. The mechanism is real. The clinical evidence is promising. At-home versions now exist in the form of laser caps, and I used one consistently while doing everything else on this list. It is not a quick fix and it will not override the biology, but as a way to actively support the follicle environment while your hormones restabilize, it became the intervention I felt most confident in. Consistency is what matters.

The hardest part, and I say this as someone who lived it, is that most of what helps is slow. Sleep more. Stress less. Eat well. Be consistent. None of it feels like enough when you are watching your hairline change in the mirror. But the follicle is intact. The biology is working. Your hair will come back. One morning you will be standing at that same drain and realize the nest is smaller, then smaller still. You will barely remember the Tuesday it started.
