The hairbrush is usually the thing that does it. You pull the hair out of the bristles and there is visibly more of it than there was last week, and the question that follows is never really why. It is how much longer.
Postpartum shedding runs on a schedule, and it is not the one most people brace for. It has a beginning, one heaviest stretch and an end, and the useful part is working out which of the three you are in. The table below is that schedule, so you can find the row you are standing on and see what is in front of you.

The timeline, month by month
| Timeframe | What is happening |
|---|---|
| Birth to ~6 weeks | Usually no shedding yet. Hormones are still shifting. |
| ~2 to 4 months | Shedding begins, often suddenly and dramatically. |
| ~4 months | The peak. This is typically the heaviest point. |
| ~5 to 8 months | Shedding eases, and short regrowth appears at the hairline. |
| ~6 to 12 months | Back to your normal hair cycle for most people. |
Why it runs this way
During pregnancy, high estrogen keeps more of your hair in its growing phase, so you shed less and your hair often feels thick and glorious. After birth, estrogen drops, and all that hair you held onto shifts into the shedding phase at once. This is called telogen effluvium. It looks alarming because it is a lot of hair leaving together, but it is your hair simply catching up on the shedding it skipped, not your hair falling out for good.
Signs it is regrowing
The reassuring milestone is those short, wispy hairs that stand up around your forehead and temples. They can be frizzy and have a mind of their own, but they mean new growth is coming through. Over the following months they lengthen and blend back in. A flattering cut for thinning hair helps them look intentional in the meantime.
When to check with your provider
Postpartum shedding is normal and self-resolving, but see your provider if it is still heavy beyond about a year, if you have distinct bald patches rather than overall thinning, or if it comes with other symptoms like fatigue, feeling cold, or weight changes, which can suggest a thyroid or iron issue worth treating. Our guides to postpartum hair loss and hair loss supplements go deeper.
Go back up to the table for a second and find yourself in it. Which row are you on today, and does it match what your hairbrush is telling you?
