Although it comes in a tiny and seemingly portable cardboard container, (good that it's not plastic!) the powder would be impossible to travel with, as the container doesn't seal. The powder is messy and flew around the bathroom counter, even though I kept my head over the sink when applying it. It feels very heavy in the hair, and doesn't help restore shine to hair that needs a wash. If anything, it makes it look duller. I tried another similar product from another eco-friendly company, and the result was the same. While I applaud the effort that goes into sustainability and non-toxic ingredients, sometimes they just don't work. I've found the same thing with shampoo bars. Sorry, I couldn't be more positive about this!
