If you've noticed more hair than usual in your brush or shower drain lately, especially as the seasons change, you're not imagining it, and you're far from alone. Seasonal hair shedding is a real, well-documented pattern, and in most cases it's completely temporary.
Why Hair Sheds More in Certain Seasons
Hair grows in cycles: an active growth phase (anagen), a short transition phase, and a resting phase (telogen) before the strand falls out to make room for new growth. Research suggests that more hairs than usual can enter the resting phase at once during seasonal transitions — most commonly late summer into autumn, and sometimes again in early spring.
The exact trigger isn't fully understood, but it's thought to be linked to changes in daylight hours, temperature, and the body's natural hormonal rhythms similar to how many animals shed seasonally, just far less dramatically in humans.
What's Normal vs. What's Not
Some extra shedding noticeably more hair on your pillow, in the shower, or on your brush for a few weeks is common and usually resolves on its own within 1–3 months. What's worth paying closer attention to:
- Shedding that continues for more than 3 months without slowing down
- Visible thinning or a widening part, rather than just more loose hairs
- Shedding accompanied by scalp itching, redness, or flaking
- A sudden, dramatic increase rather than a gradual seasonal shift
If any of these sound familiar, it may point to a different underlying cause genetic thinning, a reactive trigger like stress or illness, or a scalp condition rather than simple seasonal shedding.
What Actually Helps
Since seasonal shedding is temporary and self-resolving, the goal isn't to "stop" it it's to support your scalp and follicles through the cycle so regrowth comes back strong. A gentle, consistent routine that exfoliates buildup, calms the scalp, and nourishes weakened strands can help shorten the visible impact and support healthier regrowth once the cycle passes.
This is very similar to how we approach reactive hair loss more broadly the kind triggered by stress, illness, or hormonal shifts like postpartum changes. If your shedding fits that reactive pattern rather than a genetic or chronic one, our Reactive / Postpartum Hair Loss routine is built around exactly this kind of temporary, cause-driven shedding.

When to See a Professional
If shedding persists well beyond 3 months, comes with visible thinning rather than just loose hairs, or you're simply unsure what's causing it, it's worth a proper consultation rather than guessing. Book an online skin and hair consultation with us we can help you figure out whether what you're experiencing is seasonal, reactive, or something that needs a different approach entirely.
