I change soap once in a while just to try other things out. But if none of those is good enough to replace my favorite, I will always go back to my favorite soap. I used to love Johnson & Johnson's baby soap when I was in the Philippines then when we moved to US, I cannot find the exact same product with the exact same smell of J&J so I was forced to explore other brands. Took me a little while to find it but when I did, I no longer use other soap. But if there is something interesting in the market, I'm willing to try a new one.
