Certain medications taken by millions could be contributing to unexpected hair loss, warns Dr. Zain Hasan, an anesthetist based in Los Angeles.
Dr. Hasan explained to the Daily Mail the five commonly prescribed drugs that may lead to alopecia, a condition where hair falls out or follicles stop growing hair. While hair loss is often a natural part of aging, Dr. Hasan explained that these medications might accelerate the process.
The first drug on Dr. Hasan’s list is Wellbutrin (bupropion), an antidepressant that boosts mood by increasing levels of “feel-good” hormones in the brain.
While effective for treating depression, the medication has been associated with hair loss in both men and women. A 2018 study involving one million new antidepressant users revealed that those taking bupropion were more likely to experience hair loss compared to users of other antidepressants. Patients have shared stories online about their hair falling out while on the medication, describing the experience as emotionally distressing.
Blood thinners such as warfarin and heparin, often prescribed to prevent blood clots, are another potential cause of hair loss. These medications may interfere with the hair growth cycle, leading to shedding that patients might not immediately associate with their treatment.
Similarly, retinoid-based anti-acne medications like isotretinoin, which contain high doses of vitamin A, can disrupt normal hair growth. Excess vitamin A can push hair follicles into a resting phase, resulting in significant hair loss.
Beta-blockers, prescribed for conditions such as high blood pressure and heart disease, may also contribute to thinning hair. These medications can slow down hair growth or cause diffuse shedding across the scalp.
Lastly, chemotherapy drugs, known for their strong effects on rapidly dividing cells, often lead to widespread hair loss by targeting not only cancer cells but also the rapidly growing cells in hair follicles.
Dr. Hasan emphasizes the importance of discussing potential side effects with a healthcare provider, particularly for those concerned about hair loss. While these medications serve essential purposes in managing health conditions, understanding their impact on hair can lead to better-informed treatment decisions.
