There are some medications that can cause hair to become dry and brittle. Some can even cause hair to thin and shed excessively. If you notice your hair thinning and, are on any of the medications that we list, please check with your health care provider, read the side effects and pay attention to signs of changing hair when you're starting a new medication.

*Note: Even if you're on a medication and you don't know the side effects, read them, especially if your medication dosage has changed recently.
