Every fall, and sometimes into spring, brushes fill up. Seasonal hair loss is real and documented—but it also serves as a convenient explanation for hair loss that isn't seasonal at all. Knowing how to distinguish between the two is what truly makes a difference in treatment.

What is seasonal hair loss?
This is physiological telogen effluvium: a higher proportion of hairs enter the resting phase and then fall out a few weeks later. The main trigger is the amount of sunlight, not cold or wind. This is also why the peak in hair loss occurs in the fall, while the transition takes place in the middle of summer.
- It is diffuse, covering the entire scalp
- It lasts six to ten weeks and resolves itself
- It leaves no bald patches and does not deplete the hair follicle reserve.
Seasonal shedding has become the universal explanation. I've seen women wait three autumns in a row, telling themselves, "It's the season," while their partings widened year after year. The season doesn't create a bald patch. When a patch thins, it's no longer the season.
Seasonal hair loss or progressive hair loss: how to distinguish between them?
Reactive hair loss—seasonal, postpartum , or post-infectious —is sudden, diffuse, and temporary, and the follicle regenerates intact. Progressive hair loss, or androgenic alopecia , is slow, localized to the crown or temples, and proceeds through the gradual miniaturization of the follicle. The hair does not fall out all at once: it grows back thinner each time, until it stops growing altogether.
When a fall seasonal is no longer one
These signals indicate that it is probably no longer a seasonal fall:
- A fall that extends beyond three months
- A widening central ridge or receding gulfs
- Hair that is noticeably thinner than it was two years ago
- A fall that returns out of season, or that never really stops
- Intense fatigue is also present, suggesting an iron deficiency or thyroid disorder.

"I had been using minoxidil for years but with many side effects. I tried this
I tried the serum, thinking it wouldn't work... and yet! The bald spot on the back of my head has clearly filled in. Amazing!

Discover the solutionHow to treat seasonal hair loss?
Seasonal hair loss stops on its own; the goal isn't to halt it, but to support regrowth so it's quick and thick. We stimulate scalp microcirculation, provide the cofactors necessary for keratin synthesis, and cleanse at pH 5 without irritating an already stressed scalp . Starting in late August, before the peak, significantly changes the experience of those weeks.

To remember
- The seasonal drop is gradual and resolves itself within six to ten weeks.
- It is triggered by the duration of sunshine, not by the cold.
- It never becomes an evolutionary fall, but it can reveal it.
- A depopulating area is not seasonal.
