I started using my current 33.8 ounces of shampoo on July 11, 2019. Today, I had to buy another bottle because I’m perilously close to running out. I was hoping to get four years out of it, but I probably only have a month or so left. Coincidentally, that will be about the same time when Roe Bushey and I start our aptly named YouTube channel, Bald and Balding. Don’t worry, I’ll remind again.
