Hibiscrub as shower and shampoo pre operation - bleach warnings

On the Hibiscrub info label it says it can cause brown staining on surfaces/fabric that have been bleached. Elsewhere I've read that later bleaching of items can cause brown stains after they've been in contact with Hibiscrub. I have bleached hair - will using Hibiscrub as a shampoo stain my hair brown? Alternatively when I next get my highlights bleached, will these stain? Any advice greatly appreciated.
