Few things feel more alarming than running your hand through your hair and coming away with a lot more than usual. If this started a few months after a genuinely stressful stretch — a big move, a breakup, grief, a demanding job, an illness — you're probably not imagining it. You're likely dealing with telogen effluvium, and the good news is it's usually temporary.
Why stress causes hair to fall out (a few months later)
Your hair grows in cycles: an active growth phase (anagen), a short transition, then a resting phase (telogen) before the old hair sheds and a new one grows in. Under normal conditions, roughly 5–10% of your hair is in the resting phase at any one time. Each day, you naturally lose about 50–100 hairs from that pool.
Stress disrupts this rhythm. A significant physical or emotional stressor can push a much larger share of hair — sometimes up to 30% or more — prematurely into the resting phase at once. Because those hairs don't shed immediately, the fallout is delayed: the visible shed typically begins around two to three months after the stressful event, which is why it can feel like it came out of nowhere.
What telogen effluvium looks like
The most telling sign is that it's diffuse — the shedding is even across the scalp, not a receding hairline or a specific bare patch. You might notice extra hair in the shower drain, on your pillow, or in your brush. It's different from hereditary thinning (which is gradual and pattern-based) and from a bald patch (which can be alopecia areata).
How long does it last?
Telogen effluvium is, in most cases, self-limiting. Once the trigger resolves and your body recalibrates, the shed typically eases over a few months, and regrowth follows. Most people see it settle within three to six months and notice recovery over roughly six months to a year. If shedding continues beyond that, or you notice bald patches, it's worth seeing a healthcare professional — there can be other causes at play, from thyroid issues to nutritional deficiencies.
What genuinely helps
Because the trigger is systemic, the most important step is addressing the underlying stress or health factor — sleep, nutrition, and lowering chronic stress where you can. But while your body recalibrates, you can support the scalp so new growth comes in as healthy as possible.
- Keep the scalp environment calm. An irritated, suffocated scalp holds onto hairs less well. A gentle, paraben-free cleanse removes build-up without harsh sulphates.
- Support the root. A daily scalp tonic with root-stimulating ingredients helps encourage the growth phase — this is exactly the kind of routine our Scalp Tonic 01 Strong Roots is formulated for stress-related shedding.
- Be gentle. Avoid tight styles, aggressive brushing, and excessive heat while shedding is active.
- Give it time and consistency. Hair grows in cycles measured in months, not days. The routine that helps is the one you can stick with.
