Query: Flakes - looked like dandruff

After reading the reviews of Fiber, I decided to give it a shot. But once I started Fiber, I noticed I would get white flakes in my hair. I didn't think it was Fiber at first - I thought I had dandruff! I've never had dandruff, so I was concerned. Even my hair stylist said "looks like you have dandruff" and recommended a dandruff shampoo she sells.After her shampoo didn't work, I thought "you know, this all started when I started using Fiber". So I tried another product and stopped using the dandruff shampoo. Sure enough, flakes are gone. Ever since then, I've been flake-free (it's been 6+ months). No dandruff shampoo and a new product - no problems. In other words, it's pretty conclusive that it was Fiber causing the flakes.
