Lisinopril can cause hair loss, but it’s uncommon. Alopecia is listed as a known side effect on the FDA-approved label for lisinopril, though it occurs in a small fraction of users. If you’ve noticed your hair thinning since starting this blood pressure medication, the connection is plausible, and the good news is that it’s typically reversible.
How Common Is Hair Loss With Lisinopril?
The FDA label for lisinopril (sold under the brand name Zestril, among others) lists alopecia alongside other skin-related side effects like hives, sun sensitivity, and itching. These side effects were observed in clinical trials but are not among the most frequent complaints, which tend to be things like dizziness, cough, and headache. Hair loss from lisinopril is real, but most people who take the drug will never experience it.
Because it’s relatively rare, drug-induced hair loss from lisinopril often goes unrecognized at first. Many people attribute the shedding to stress, aging, or genetics before considering their medication. That delay is understandable, especially because the hair loss can begin weeks or even months after starting the drug, making the connection less obvious.
What This Type of Hair Loss Looks Like
Medication-induced hair loss typically presents as diffuse thinning rather than bald patches. You might notice more hair in your brush, on your pillow, or in the shower drain. It tends to affect the entire scalp rather than one specific area, which distinguishes it from conditions like alopecia areata (patchy, immune-driven hair loss) or male-pattern baldness that follows a receding hairline.
The mechanism likely involves the drug pushing hair follicles prematurely from their growth phase into a resting phase, a process called telogen effluvium. Because hair follicles have a natural resting period of about two to three months before they shed, you may not connect new hair loss with a medication you started months earlier. This lag is one of the trickiest parts of identifying any drug as the cause.
Does Hair Grow Back After Stopping Lisinopril?
Yes. In documented cases, hair loss from lisinopril has reversed after the medication was stopped. A case report published in the medical literature described a patient whose hair loss resolved within four weeks of discontinuing lisinopril. That’s a relatively fast recovery, though individual timelines will vary. For most drug-induced hair shedding, regrowth takes anywhere from a few weeks to several months as follicles re-enter their active growth cycle.
The key factor in recovery is correctly identifying the medication as the cause. Once lisinopril is removed and no other factors are driving hair loss (thyroid problems, nutritional deficiencies, other medications), the follicles are not permanently damaged. They simply resume their normal cycle.
Ruling Out Other Causes
Before assuming lisinopril is the culprit, it’s worth considering other common reasons for hair thinning. Several of these overlap with the population most likely to be taking blood pressure medication:
- Thyroid disorders: Both overactive and underactive thyroid function can cause diffuse hair loss that looks very similar to drug-induced shedding.
- Iron deficiency: Low iron levels are a well-established cause of hair thinning, particularly in women.
- Other medications: Beta-blockers, blood thinners, cholesterol-lowering drugs, and certain antidepressants can all contribute to hair loss. If you take multiple medications, lisinopril may not be the one responsible.
- Stress and illness: A major surgery, infection, or period of emotional stress can trigger telogen effluvium on its own, and the timing may coincidentally overlap with starting a new prescription.
A simple blood panel checking thyroid function and iron levels can help narrow things down. The strongest clue that lisinopril is the cause is a clear timeline: hair loss that began within a few weeks to a few months of starting the drug, with no other obvious triggers.
Alternative Blood Pressure Medications
If lisinopril is causing your hair loss, switching to a different class of blood pressure medication is a straightforward option. Lisinopril belongs to the ACE inhibitor family, and alopecia has been reported across this drug class, not just with lisinopril specifically.
Two classes of blood pressure medication are generally not associated with hair loss: calcium channel blockers (such as amlodipine) and angiotensin II receptor blockers, commonly called ARBs. ARBs work on the same blood pressure pathway as ACE inhibitors but through a slightly different mechanism, making them a particularly natural alternative. Your prescriber can evaluate which option fits your overall health profile.
Stopping lisinopril on your own is not advisable, since uncontrolled blood pressure carries serious risks. The better approach is to bring up the hair loss at your next appointment, discuss the timeline, and explore a medication switch if the pattern fits. In most cases, this is a simple adjustment that resolves both the blood pressure concern and the hair loss.
