Does Lisinopril Cause Hair Loss?

Lisinopril is one of the most commonly prescribed blood pressure medications in the United States, taken by millions of people. If you've noticed increased hair shedding after starting this medication, you're not alone in wondering whether there's a connection.

Understanding how lisinopril and other blood pressure medications can affect hair loss can help you make informed decisions about your treatment options.

How Common Is Hair Loss from Lisinopril?

According to the FDA prescribing information for Zestril (a brand name for lisinopril), alopecia (hair loss) is listed as a known side effect. However, it's relatively rare:

• Less than 1% of patients experience hair loss in clinical trials
• Some studies suggest the rate may be less than 0.1%
• Hair loss is not among the most common side effects (which include cough, dizziness, and headache)

How Lisinopril Can Cause Hair Loss

Lisinopril belongs to a class of medications called ACE inhibitors (angiotensin-converting enzyme inhibitors). Here's how it may affect hair:

The Mechanism

ACE inhibitors work by blocking the enzyme that produces angiotensin II, a substance that narrows blood vessels. While this effectively lowers blood pressure, it can also:

• Affect aldosterone levels: Aldosterone helps regulate hair growth cycles. Disrupting this hormone may push follicles into the resting phase prematurely
• Reduce zinc levels: Some ACE inhibitors may increase zinc excretion, and zinc is important for hair health
• Cause telogen effluvium: The body's adjustment to the medication can trigger temporary hair shedding

Timeline of Hair Loss

Drug-induced hair loss typically doesn't appear immediately:

• 2-4 weeks after starting: Follicles begin shifting to resting phase
• 2-3 months after starting: Noticeable shedding typically begins
• 3-6 months: Shedding may continue or stabilize

This delay is why people often don't connect their hair loss to a medication they started months earlier.

Other Blood Pressure Medications That Cause Hair Loss

Lisinopril isn't the only antihypertensive linked to hair loss. Several classes of blood pressure medications can cause or contribute to hair shedding:

Is the Hair Loss Reversible?

Yes, in most cases. Lisinopril-induced hair loss is typically a form of telogen effluvium, which is temporary:

What Is Telogen Effluvium?

Telogen effluvium is a condition where a stressor (like medication) pushes more hair follicles than usual into the resting (telogen) phase. This causes increased shedding but doesn't destroy the follicles permanently.

What to Do If You Suspect Lisinopril Is Causing Hair Loss

If you've noticed hair loss after starting lisinopril, here's what to consider:

1. Don't Stop Your Medication Abruptly

This is critical. Lisinopril is prescribed for serious conditions like high blood pressure and heart failure. Stopping suddenly can be dangerous. Always consult your doctor before making any changes.

2. Talk to Your Doctor

Discuss your concerns with your prescribing physician. They can:

• Evaluate whether the hair loss is truly medication-related
• Consider alternative blood pressure medications
• Adjust your dosage (sometimes a lower dose reduces side effects)
• Order blood tests to rule out other causes

3. Consider Alternative Medications

Several blood pressure medications are less likely to cause hair loss:

• ARBs (Angiotensin Receptor Blockers): Losartan, valsartan—work similarly to ACE inhibitors but via a different mechanism
• Calcium channel blockers: Amlodipine—very rarely associated with hair loss
• Minoxidil: Actually promotes hair growth (though requires careful dosing for blood pressure)

4. Rule Out Other Causes

Hair loss often has multiple contributing factors. Before blaming lisinopril, consider:

• Timing: Did hair loss start within 2-4 months of starting the medication?
• Pattern: Is it diffuse thinning (typical of drug-induced) or patchy/patterned?
• Other factors: Stress, nutritional deficiencies, thyroid issues, hormonal changes
• Genetics: Pattern baldnessmay be coincidentally progressing

Managing Hair Loss While on Lisinopril

If you need to continue taking lisinopril for your health, you can still take steps to support your hair:

Nutritional Support

• Zinc: ACE inhibitors may deplete zinc; consider supplementation (after consulting your doctor)
• Iron: Ensure adequate iron levels
• Protein: Hair is made of protein; ensure adequate intake
• B vitamins: Support overall hair health

Hair Growth Treatments

• Minoxidil (Rogaine): Can help counteract hair loss while on lisinopril; check with your doctor about interactions
• Ketoconazole shampoo: May have mild hair growth benefits
• Gentle hair care: Avoid harsh treatments that could worsen thinning

Lifestyle Factors

• Manage stress: Stresscompounds drug-induced hair loss
• Exercise regularly: Good for blood pressure and overall health
• Avoid smoking: Smokingdamages hair follicles

Other Medications That Cause Hair Loss

Lisinopril is just one of many medications that can affect hair. Other common culprits include:

Frequently Asked Questions

How quickly does hair loss start after taking lisinopril?

Hair loss from lisinopril typically begins 2-3 months after starting the medication. This delay occurs because drug-induced telogen effluvium affects the hair growth cycle, and it takes time for affected hairs to reach the shedding phase. If you notice hair loss within days of starting lisinopril, another cause is more likely.

Will my hair grow back if I stop taking lisinopril?

Yes, in most cases. Hair loss from lisinopril is typically telogen effluvium, which is reversible. Once you stop the medication (with your doctor's approval), shedding usually stops within 1-3 months, and regrowth begins within 3-6 months. Full recovery may take 6-12 months.

Can I take hair growth supplements while on lisinopril?

Generally yes, but check with your doctor first. Supplements like biotin, zinc, and iron are usually safe with lisinopril. Minoxidil (a topical hair growth treatment) is also typically compatible, but since it also affects blood pressure, your doctor should be aware you're using it.

Is lisinopril or losartan better for hair loss?

Losartan (an ARB) may be slightly less likely to cause hair loss than lisinopril (an ACE inhibitor), though both are rare. If you're experiencing hair loss on lisinopril, switching to losartan or another ARB might be worth discussing with your doctor—they work similarly for blood pressure control.

Does everyone on lisinopril experience hair loss?

No, hair loss from lisinopril is rare—affecting less than 1% of users. Most people take lisinopril for years without any hair effects. If you're starting lisinopril, hair loss should not be a major concern, though you can monitor for changes.

Can adjusting my lisinopril dose help with hair loss?

Possibly. In some cases, side effects like hair loss are dose-dependent. Your doctor might consider lowering your dose while maintaining blood pressure control. However, never adjust your dose without medical guidance—proper blood pressure management is essential for your health.

Should I see a dermatologist about lisinopril-related hair loss?

Yes, if the hair loss is significant or doesn't improve after addressing the medication. A dermatologist can evaluate whether the hair loss is truly drug-related, rule out other causes, and recommend treatments to support regrowth while you manage your blood pressure.

Conclusion

While lisinopril can cause hair loss, it's a rare side effect affecting less than 1% of users. If you do experience shedding, it's typically temporary telogen effluvium that reverses once the medication is stopped or changed.

However, never stop blood pressure medication without consulting your doctor. High blood pressure is a serious condition that requires proper management. If you're experiencing hair loss, work with your healthcare provider to explore alternatives or supportive treatments.

Remember that hair loss often has multiple causes. Even if you're on lisinopril, other factors like genetics, stress, or nutritional deficiencies may be contributing. A thorough evaluation by a dermatologistcan help identify all the factors affecting your hair.
