Wow. I highly doubt there is any nutritional value to drinking the water that a brush has soaked in. Someone should ask him to back up his claim with scientific research. “Protein and keratin” as he says, is the same thing. In fact, hair is simply Keratin, which is a type of protein. You’re soaking the brush for what...20 min maybe? I guess he thinks some of the keratin has leached off the hair during that time? Give me a break.
