Do Statins Cause Hair Loss? What the Labelling Says
Do statins cause hair loss? For some of them, yes — but uncommonly, and not for all of them. Hair loss is listed in the official product information for some statins and not others. Atorvastatin lists alopecia as an uncommon effect — between 1 in 1,000 and 1 in 100 users. Simvastatin lists it as rare, between 1 in 10,000 and 1 in 1,000. Rosuvastatin does not list it at all.
That is the short answer to “do statins cause hair loss”. The longer one matters, because statins are usually started at exactly the age when hereditary hair loss becomes visible anyway, and telling the two apart decides what you should do next.
Do statins cause hair loss? What the labelling shows
Every prescription medicine in the UK and EU carries a Summary of Product Characteristics (SmPC) with a section listing undesirable effects and how often each has been observed. This is regulatory data, not opinion, so it is the right place to start.
| Statin | Common brand | Alopecia in the SmPC? | Stated frequency |
|---|---|---|---|
| Atorvastatin | Lipitor | Yes — “Uncommon: urticaria, skin rash, pruritus, alopecia” | Uncommon — ≥1/1,000 to <1/100 |
| Simvastatin | Zocor | Yes — “Rare: rash, pruritus, alopecia” | Rare — ≥1/10,000 to <1/1,000 |
| Rosuvastatin | Crestor | No — skin effects listed are pruritus, rash and urticaria | Not listed |
Two things follow from this table, and both are commonly got wrong by pages answering “do statins cause hair loss”.
First, “uncommon” and “rare” are not vague words here. They are defined categories with numbers attached. Uncommon means fewer than one person in a hundred; rare means fewer than one in a thousand. Most people taking atorvastatin will not lose hair because of it.
Second, a drug not listing alopecia does not prove it never causes it. It means the effect was not observed often enough in trials and post-marketing reporting to be listed. Individual case reports of alopecia associated with rosuvastatin exist in the medical literature; they have not amounted to a labelled frequency.
What statin-related hair loss looks like
Drug-induced hair loss is almost always telogen effluvium — the drug pushes a larger than normal proportion of follicles out of their growth phase and into shedding. DermNet describes it as “a usually reversible nonscarring diffuse hair loss”, and notes that with telogen effluvium “the hair loss usually becomes evident after 2–4 months”.
Three features distinguish it from hereditary hair loss:
| Statin-related shedding | Hereditary (pattern) hair loss | |
|---|---|---|
| Distribution | Diffuse — the whole scalp thins evenly, including the back and sides — see diffuse thinning | Patterned — temples, hairline and crown; the back and sides are spared. The Norwood scale maps the stages |
| Onset | 2–4 months after starting the drug or changing the dose | Gradual over years, with no starting point you can name |
| What you notice | More hair in the drain, on the pillow, in the brush | Less hair in a specific area; shedding is often normal |
| Individual hairs | Normal calibre — you are losing hairs, not thinning them | Finer and shorter over time, which is miniaturisation |
| Course | Settles once the cause is removed | Progresses without treatment |
The coincidence problem
This is the part most pages skip when they answer “do statins cause hair loss”, and it is the most useful thing on this one.
Statins are typically first prescribed to men in their forties and fifties. That is also the decade in which androgenetic hair loss becomes unmistakable — it has usually been progressing quietly for ten to fifteen years and simply crosses the threshold of visibility around then. Two unrelated things happen in the same year, and the new one gets the blame.
The distribution test above settles it in most cases. If the back and sides are as dense as ever and the loss is at the temples and crown, the statin is almost certainly not the cause, whatever the timing suggests. If the whole scalp including the nape is thinner and it began two to four months after the prescription, the timing is meaningful.
A second, more common possibility is worth naming: the illness or event that led to the statin being prescribed — a cardiac episode, surgery, a period of significant stress or rapid weight change — is itself a well-established trigger of telogen effluvium, on the same two to four month delay. The shedding may be real and the drug may still not be the reason.
Why the link is hard to prove either way
Anyone asking “do statins cause hair loss” deserves to know why the numbers in the table are as low as they are, because it changes how you should read them.
Frequencies in a product’s labelling come from two sources: rates observed in clinical trials, and spontaneous reports collected after the medicine reaches the market. Neither is well suited to hair. Trials of cholesterol medicines are designed to measure cardiovascular events over years, and hair shedding two to four months in is not an endpoint anyone is recording. Spontaneous reporting depends on a patient noticing, connecting it to the drug, telling their doctor, and the doctor filing a report — a chain that breaks at every link for something as unalarming as hair.
Running the other way is the confounding problem. The population taking statins is the population in which hereditary hair loss becomes visible, in which thyroid disease and iron deficiency are common, and which has often just been through the cardiac event or diagnosis that led to the prescription. Every one of those produces the same picture on the same timescale.
The result is a genuinely uncertain evidence base: a labelled effect at low frequency, a plausible timeline, no established mechanism, and a great deal of noise. That uncertainty is the honest answer, and it is why the distribution and timing tests above are more useful to you than any general statement about statins.
Will hair lost this way grow back?
Usually, yes. Telogen effluvium does not scar and does not destroy follicles; it interrupts their cycle. DermNet puts the recovery timeline plainly: once the cause is removed, “hair shedding settles, although this may take up to 6 months”, and “evidence of hair regrowth is usually seen within 3–6 months but can take 12–18 months to recover cosmetically”.
That last figure is the one to hold on to. Regrowth begins long before it looks like anything, and the gap between “growing again” and “looking normal again” is where most people conclude, wrongly, that nothing is happening.
Other cholesterol medicines
Labelling differs between products and manufacturers, so the only reliable check for a specific medicine is its own Summary of Product Characteristics rather than a general article. As a guide to what to look for:
| Medicine | What to check |
|---|---|
| Pravastatin, lovastatin, fluvastatin, pitavastatin | Look for “alopecia” in section 4.8 of that product’s SmPC and note the frequency heading above it. Generic versions of the same molecule can differ in wording between manufacturers. |
| Ezetimibe | Not a statin — it blocks cholesterol absorption rather than its synthesis. It is often taken alongside a statin, which makes attribution harder when shedding starts. |
| Combination products | Where two molecules are in one tablet, either can be responsible; the SmPC lists effects for the combination. |
The patient information leaflet in the box lists the same effects in plainer language, and both are published free on the electronic Medicines Compendium.
What helps while it recovers
There is no treatment that shortens telogen effluvium itself. The follicles restart on their own schedule and nothing reliably accelerates that. What is worth doing falls into three groups.
| Worth doing | Why |
|---|---|
| Rule out the common co-causes | Iron and ferritin, thyroid function and vitamin D produce the same diffuse shedding and are correctable. A shedding episode blamed on a drug is often partly one of these. |
| Reduce breakage | Hair already thinned by shedding is more conspicuous when it also snaps. Gentle handling, less heat, no tight styles while wet. |
| Photograph monthly | Recovery is slow enough to be invisible day to day. Photographs are what stop people abandoning a correct plan too early. |
| Wait out the interval before concluding | Shedding settles within about six months of the cause being removed. Judging it at six weeks tells you nothing. |
What is not worth doing is starting a hair-loss treatment on the assumption that the diagnosis is pattern hair loss, before establishing that it is. If the shedding is diffuse and drug-related, it resolves on its own; if the underlying picture is androgenetic alopecia that the shedding merely exposed, that is a different plan with a different timescale — and the two frequently coexist. The distinction between shedding and loss is the one worth getting right before spending anything.
What to do — and what not to do
If you have concluded that the answer to “do statins cause hair loss” is yes in your case, one rule comes before everything else. Do not stop or change a statin on your own. That is not caution for its own sake: statins are prescribed to reduce cardiovascular risk, and that decision belongs to the doctor who made it, weighed against your own numbers. Hair is a reason to have the conversation, not a reason to skip it.
What is useful to bring to that conversation:
| Bring | Why it helps |
|---|---|
| The date you started, and any dose changes | Lets the two to four month interval be checked against when the shedding began. |
| Photographs of the crown and hairline over time | Distinguishes diffuse shedding from a patterned change, which is the whole question. |
| Whether the back and sides have thinned too | The single most informative observation you can make yourself. |
| Other events in the same window | Illness, surgery, weight loss and other new medicines all cause the same picture. |
| Recent bloods, if you have them | Iron, ferritin and thyroid function produce identical diffuse shedding and are easily missed. |
If a statin is confirmed as the trigger, the prescriber may switch you to a different one — which is where the SmPC table above becomes practically useful rather than academic.
Frequently asked questions
Do statins cause hair loss?
Some do, uncommonly. Atorvastatin lists alopecia as an uncommon side effect (fewer than 1 in 100 users) and simvastatin lists it as rare (fewer than 1 in 1,000). Rosuvastatin does not list it. Where it happens it is diffuse shedding rather than pattern balding, and it is usually reversible.
Does atorvastatin cause hair loss?
It is listed in the atorvastatin SmPC under “Uncommon: urticaria, skin rash, pruritus, alopecia”, where uncommon is defined as between 1 in 1,000 and 1 in 100 people. So it is a recognised but infrequent effect. Note that the NHS patient-facing side effect page for atorvastatin does not mention hair loss, because that page lists the common effects only.
Can Lipitor cause hair loss?
Lipitor is the original brand of atorvastatin, so the same labelling applies: alopecia is listed as uncommon.
Can Crestor or rosuvastatin cause hair loss?
Alopecia is not listed in the rosuvastatin SmPC. Isolated case reports exist in the literature, but the effect has not been observed often enough to appear in the product information with a frequency attached.
Can simvastatin cause hair loss?
Yes, listed as rare — between 1 in 10,000 and 1 in 1,000 users.
Which statins do not cause hair loss?
On current labelling, rosuvastatin does not list alopecia while atorvastatin and simvastatin do. That is a difference in what has been observed and reported, not a guarantee about any individual. Any switch between statins is a decision for the prescriber.
Can statins cause hair loss in women?
The labelled frequencies are not sex-specific. What differs is the background: diffuse thinning in women has a longer list of common causes — iron deficiency, thyroid disease, postpartum shedding, menopause — so the drug is less often the explanation than it first appears. The distribution and timing tests apply the same way.
Can cholesterol medicine cause hair loss?
Some cholesterol medicines list it and some do not, and the frequency where listed is low. DermNet includes cholesterol-lowering drugs generally among the causes of telogen effluvium. The specific answer for your medicine is in its own Summary of Product Characteristics.
Crestor or Lipitor — which is more likely to affect hair?
On labelling alone, Lipitor (atorvastatin) lists alopecia as uncommon and Crestor (rosuvastatin) does not list it. That is a difference in what has been observed and reported, not a prediction for any individual, and it is not on its own a reason to request a switch.
Can statins cause hair thinning rather than shedding?
The two are different and the distinction matters. Shedding means more hairs leaving than usual, with the remaining hairs normal. Thinning means the individual hairs becoming finer, which is miniaturisation and is the signature of hereditary hair loss. Drug effects produce shedding.
Will hair loss from statins grow back?
Usually. Shedding settles within about six months of the cause being removed, visible regrowth follows within three to six months, and full cosmetic recovery can take twelve to eighteen months.
How long after starting a statin would hair loss appear?
Two to four months, which is the normal delay for telogen effluvium. Shedding that begins within days of the first tablet, or two years in, is unlikely to be the drug.
In short
Do statins cause hair loss? Atorvastatin and simvastatin list it at low frequency, rosuvastatin does not list it, and where it happens it is diffuse shedding that usually reverses. Before attributing it to the drug, check whether the back and sides thinned too, and whether it began two to four months after starting. Then take that to the prescriber rather than acting alone.
Never stop or change a prescribed statin because of hair loss without speaking to the doctor who prescribed it — the cardiovascular reason it was started does not go away. If the shedding continues after the drug question has been settled, it is worth having the scalp itself assessed: trichoscopy distinguishes drug-related shedding from pattern hair loss, which behaves and is treated differently.
