I think that's a difficult task. Most products have formula changes, so few are consistent for 10 years. Personally, I've only been using products for about 6 years. When you're first on nc.com, you want to try every product that anyone mentions. Eventually, you get to know your hair and it becomes easier to know what it might like by reading the ingredients.
I'm an acknowledge product slut. I doubt I'm using anything that I used five years ago. I do occasionally use KCCC. However, if I couldn't get it again, it would be fine. I continue to use natural soap bars to cleanse.
