Some people are very brand loyal and once they have found a shampoo or shower gel or other toiletry that they like, they stick with it forever! Others like to chop and change all the time.
Do you like trying new toiletries or do you always stick with the same brands?
I only use bi-carb and apple cider vinegar and natural hand made soap. Recently I've started using a hand made shampoo soap that I quite like too. If I find something I like I use it until I find something I like more.
