I took accutane 10 years ago. It made my hair fall out. I had extremely thick, hair that was heavy and difficult to manage. I was left with 25% of my hair. From being unable to put my hair in a ponytail due to the weight and thickness, my ponytail became stringy and thin. It took a couple years to grow back, but never grew back to the original state. It grew back to 50% of my original hair. I then experienced another phase of hair loss a few years later.
Also, while accutane worked to heal acne while i took it, two years later it came back and I still have acne.
