We live in a world where a healthy head of hair is highly coveted—much like flawlessly clear skin and being able to squeeze into your high school jeans. But unfortunately, many people don’t know that certain medications can cause mild to severe hair loss as a side effect. Acne drugs like Accutane are proven to cause hair woes in some patients, as are certain blood thinners, antidepressants, antifungals and hormone therapies. So the question of what matters most is up to you (i.e., clear skin or healthy hair?). You can always check with your doctor about alternative treatments if your symptoms are bothersome.
