QCS Shampoo bar
Let me preface this by saying that I don't have that much experience with shampoo bars in general. I've used Liggett's for a few days and found it to be mundane, but acceptable. I ordered the Tea Tree and Lavender shampoo bar from Queen Charlotte Soaps to see if some shampoo bars are better than others. I found the QCS bar to be much better than the Liggett's, in several ways. The scent was better, easily. I felt it left my hair a little softer and not as clumpy feeling. It lathered very well, maybe not quite as good, but still performed well. Part of this may be me getting acclimated to shampoo bars in general, but so far I'm finding the QCS to be a good option.
