i really like the inbetween formula. It is keeping my hair so clean and I just love it! I look so different than I did even last July when I did my first humaworm cleanse. Thank you HUMAWORM! You are literally giving me my life back. My mom is on it too -- age 82 went to the hairdresser who commented how incredibly thick and different her hair is. I didn't quite mention parasites because people aren't always receptive to it. Maybe next time.
