2. Drug Dependence
According to research from WebMD, several prescription and recreational drugs can result in hair loss in both men and women—including antidepressants or mood stabilizers, acne medications, immunosuppressant medications, blood thinners, steroids, cholesterol-lowering medication, weight loss drugs, oral contraceptives, thyroid medications, chemotherapy drugs, and more.
Of course the severity of hair loss depends on the type and dosage of drugs you’re taking, in addition to personal drug sensitivity. Drug-induced hair loss comes in two forms—Telogen Effluvium, which occurs within 4-months of taking the drug and results in resting hair follicles and early hair loss—and Anagen effluvium, which occurs within weeks of taking a new medication (i.e., chemotherapy) and causes hair to shed during the anagen, or active growth phase of the hair cycle.
