In short their are two kinds of black soap: One from Nigeria and one from Ghana. The one from Ghana is called Alata Samina and is soft, crumbly and brown. The one from Nigeria is hard and dark brown, it's called Dudu Osun. Coastal Scents sells the Alata Samina Version, the ghana soap not the Dudu Osun. the ones you can find on Amazon, packaged in those green boxes is the Nigerian version..They are both natural and are both authentic african black soaps. Now I will admit Coastal scent shipping is a bit intimidating for me, if shipping is putting you off, there are a number of sites where you can order real black soap, including Hosia Online for less than 7 bucks. btw bith soaps can be super drying if you're not careful. only use what you need and whatever you do, do not scrub you face! Let me be the one to tell you, Dudu Osun is still burning me right now and I used it this morning before I went to work. There's a video on youtube of a lady showing people how to use the soap. Basically she says just use a film and not the whole lather.
