Hair loss sends most people straight to the supplement aisle, usually for biotin. For most, that is the least useful place to start. Hair is a downstream signal, and the fix is almost always upstream.
Here is a more practical hair loss guide, in the order worth working through it, and the reason behind each step.
This guide is what to try on your own. If shedding has gone on for months, or the pattern is changing, the ferritin, thyroid and hormone work is a clinical job. Naturopathic care for hair loss in Ontario
1. Eat more protein
Hair is made of keratin, which is a protein. When you are under-eating or running low on protein, the body deprioritizes hair, and shedding is one of the earliest signs. Crash diets and very low-calorie eating are common, overlooked triggers, and adequate protein and overall nutrition are foundational for hair (Guo and Katta, 2017, PubMed: 28243487).
2. Get the right blood tests
Some of the most common causes are invisible without testing. Low iron stores (ferritin), an under- or over-active thyroid, and low vitamin D or B12 can all drive shedding. Research links low serum ferritin specifically to hair loss in women (Aslam et al., 2022, PubMed: 36601197). The point is simple: test, do not guess, because you cannot feel any of these.
3. Care for your scalp
A healthy scalp grows healthier hair. Keep it clean and hydrated, and address inflammation, flaking, or product buildup, all of which can disrupt the environment the follicle depends on. Scalp care is not glamorous, but a chronically irritated scalp works against everything else you do.
4. Balance your hormones
Hormones are a major driver of shedding in women. PCOS, with its excess androgens, the sharp postpartum drop in estrogen, and the shifts of perimenopause are all classic triggers. If your shedding lines up with one of these stages, the hormonal picture is worth investigating rather than treating the hair in isolation.
5. Manage your stress
Sudden, diffuse shedding, known as telogen effluvium, often shows up two to three months after a stressful stretch, an illness, surgery, or a major life event. That lag is exactly why people miss the connection. The good news is this type usually settles on its own once the trigger has passed and stress is managed.
6. Try scalp massage
A few minutes of daily scalp massage is low-risk and has some supporting evidence. A small study found that standardized daily scalp massage increased hair thickness over several months, proposed to work through gentle mechanical stretching of the follicle cells and improved blood flow to the scalp (Koyama et al., 2016, PubMed: 26904154). It is not a miracle, but it is a cheap, easy thing to add.
A note on supplements
The instinct is to reach for biotin. But biotin only helps if you are genuinely deficient, which is uncommon, and high doses can even interfere with some blood tests. The smarter approach is to test first, then supplement the specific gaps you actually have, such as iron, vitamin D, or zinc, rather than taking a random hair vitamin and hoping (Guo and Katta, 2017, PubMed: 28243487).
When to get it assessed
A little extra shedding during a stressful season is often temporary and self-correcting. But hair loss that lasts beyond a few months, comes with a widening part or visible thinning, or pairs with fatigue and other symptoms, is worth a proper workup. Most hair loss in women is far more treatable when you find and address the actual driver early, rather than masking it.
Frequently Asked Questions
Does biotin actually help with hair loss?
Only if you are genuinely deficient in it, which is rare in people who eat a normal diet. For most people, biotin supplements do little for hair, and high doses can interfere with certain lab tests, including thyroid and heart markers. A better approach is to test for the deficiencies that actually drive shedding, like low iron, and address those specifically.
What blood tests should I ask for?
A useful starting panel includes ferritin (your iron stores), a full thyroid panel, vitamin D, and vitamin B12. Depending on your history, androgens and other hormones may be added. Low ferritin in particular is strongly associated with hair loss in women, and it is one of the most common and fixable causes.
Can stress really cause hair loss?
Yes. A physical or emotional stressor can push a large number of hairs into the shedding phase at once, a pattern called telogen effluvium. It typically appears two to three months after the event, which is why the link is easy to miss, and it usually recovers once the stress resolves and the body rebalances.
Does scalp massage actually work?
The evidence is limited but promising. A small study found that several minutes of standardized daily scalp massage increased hair thickness over months, thought to work through mechanical stimulation of the follicle and improved blood flow. It is not a substitute for addressing the root cause, but as a low-risk daily habit, it is reasonable to try.
Is hair loss from these causes reversible?
Often, yes, especially when caught early and when the underlying driver is addressed. Shedding from low iron, thyroid issues, stress, or postpartum changes commonly improves once the cause is corrected. Reversibility depends on the type and how long it has been going on, which is exactly why getting it properly assessed matters.
