"Started this 11 weeks ago. I am so so sad right now. I have been having horrible hair loss the past couple weeks and couldn&#039;t figure out why. Just figured out it is the Tazorac! Read up on the side effect of hair loss. It&#039;s really bad. My hair was so healthy and nice. I literally have almost bald areas with sparse hairs over my ears and my front hairline. It feels thin everywhere but I can&#039;t see it. Stay away from Tazorac."
