It usually starts with a quiet mention. Halfway through the appointment. Almost an afterthought.
"I've been losing so much hair lately."
She says it lightly, but there's a look underneath - like she's hoping you'll say it's normal. That it's nothing. That everyone goes through it.
And then there's the other version: the woman who doesn't mention it at all, but you can see it. The parting's wider. The ponytail's thinner. The hairline looks different. She knows. She just hasn't said it out loud yet.
Both women tend to share one thing in common. They can't pinpoint why it started.
The Four-Month Delay
Here's what most people don't realise about hair shedding: it almost never happens in real time.
Your sympathetic nervous system - the system responsible for your stress response - connects directly to the hair follicle. When your body is under significant pressure, it triages. It redirects energy and resources toward the functions it considers essential for survival: your organs, your immune system, your basic metabolic processes. Hair is not on that list.
So the follicle gets the signal to pause. The hair is pushed from its active growth phase into a dormancy stage, where it sits - sometimes for weeks, sometimes for months - before eventually releasing.
The shedding you notice today didn't start today. It started roughly three to four months ago, when your body decided it had bigger priorities.
By the time the hair falls, you've often forgotten what you were going through back then. The stressful period has passed. Life has moved on. So the shedding feels random. It feels disconnected. It feels frightening.
And the fear itself becomes another form of stress - which feeds the very cycle that caused it.
What Counts as Stress
When we say "stress," most people think of the obvious: work pressure, financial anxiety, relationship strain, grief. And those absolutely qualify.
But the body's definition of stress is broader than the mind's.
Illness - even a relatively mild one - is stress. Surgery is stress. A significant dietary change is stress. Rapid weight loss is stress. Starting or stopping medication is stress. Hormonal shifts - perimenopause, postpartum, coming off contraception - are stress on the system, even when they're expected.
This is worth noting because we're seeing more of this in the studio than ever before. Women who are otherwise healthy, otherwise managing well, but whose bodies have been quietly under load in ways they haven't connected to their hair.
The rise of GLP-1 medications is one example. Women experiencing rapid weight changes - intentional, medically supervised, and often positive for their overall health - are sometimes seeing shedding as a downstream effect. The body reads rapid change as a system event, regardless of whether that change is welcome.
It's not a judgement. It's physiology. And once you understand the mechanism, you stop blaming yourself for it.
Why Topical Solutions Aren't Enough
The instinct, understandably, is to fix it from the outside. A thickening shampoo. A scalp serum. A supplement from the chemist. Something - anything - that feels like action.
And some of those things can help, marginally. But if the shedding is driven by an internal trigger - stress, hormonal imbalance, nutritional deficiency, systemic change - no topical product will resolve it. You're treating the surface while the conversation is happening underneath.
Hair health doesn't start in the shower. It starts in the bloodstream.
The follicle needs adequate iron, zinc, vitamin D, biotin, protein, and omega fatty acids to produce healthy hair. It needs a balanced hormonal environment. It needs a nervous system that isn't in a constant state of alert. When any of those inputs are compromised, the hair reflects it - usually with a delay that makes the cause difficult to trace.
What Actually Helps
The first thing that helps is understanding. Knowing that the shedding isn't random, that it isn't your fault, and that it follows a biological logic - even when it doesn't feel logical - takes the fear out of it. And reducing the fear reduces one of the inputs that's sustaining the cycle.
Beyond that, the approach needs to be internal.
Nutritional support is the foundation. Not in a vague "eat well" sense - in a specific, targeted sense. The nutrients the follicle requires for healthy hair production are well documented, and many women are deficient in at least one of them without knowing it. Iron and ferritin levels, in particular, are frequently low in women and rarely tested unless specifically requested.
This is where Glowwa sits in our approach. It's a targeted hair food we carry at Common Thread - not because we're interested in selling products, but because the formulation specifically addresses the nutritional gaps that show up most often in women experiencing shedding, thinning, or fragile hair. It's one piece of a broader conversation, not a magic fix. But it's a piece that consistently makes a difference when the internal environment is part of the problem.
Equally important is understanding what triggered the shedding in the first place. If the trigger is ongoing - chronic stress, unresolved hormonal imbalance, medication side effects - supplementation alone won't be enough. The trigger needs to be identified and, where possible, addressed. Sometimes that means blood work. Sometimes it means a conversation with your GP. Sometimes it means simply connecting the dots between a life event four months ago and what your hair is doing now.
It's Not Random and You're Not Imagining It
If you're finding more hair in the shower, on your pillow, in your brush - and it feels like it came out of nowhere - it almost certainly didn't.
Your body is talking. The shedding is the message, not the problem. And once we understand the message, we can start to respond to it properly.
That doesn't happen overnight. Hair recovery is slow - it follows the same timeline as the cycle that caused the loss. But it does happen, consistently, when the right inputs are in place and the underlying cause is addressed.
