Tip for your shampoo bar
I always find that leaving a cap on after washing my hair seems to keep in the moisture. My hair would tend to go a bit mad (like it has a mind of its own) if I didn't do this. This seems to tame the hair strands down leaving the hair feeling soft and calm. After a while, possibly an hour, I take the cap off let the hair fully dry. This seems to work for me.
By the way, I never fail to be amazed at how squeaky clean my hair is left after using my shampoo bars. I feel if I were with exceptional hearing (which I'm not) I would hear the hair actually squeaking with cleanliness, like when you wash windows and they almost talk to you giving thanks for taking off all the grubbiness and dirt from them. Don't take my word for it though!! Try it!!!
