I always wondered why there weren't more reviews of the products here.
The Black Earth conditioner is excellent! It has been in my rotation of conditioners. I have used the Black Earth Shampoo with very good results as well. A friend recommended the shampoo to me because she said that after she used it, she noticed lots of hair growth.
When I finally got around to buying BE shampoo, I loved it. I can't say that it made my hair grow, but it didn't dry my hair out like other shampoos had, which led to better retention due to less detangling and rough wet handling of my hair.
TW was the first product line I found in the BSS that didn't have SLS or parabens in the product. I think that's changed now, and there is SLS in the shampoo and preservatives too - which I can mildly appreciate. I had to toss two bottles of BE shampoo and conditioner because mold began to grow inside the product.
I found that her African Healing Oil was a bit too greasy for my hair. It could be that I used too much, but the smell was nice - it does get a little cloying though.
I used the Herbal Strengthener, but didn't like it so much. I think it had herbs in it, if I remember right, and I don't like herbs in my hair.
And of course, the Bodifier was awesome! I haven't used it in a while but it always made my hair very soft. The only thing about the Bodifier, is that I could only use it once and then I'd have to rinse to reapply. Again, I could have been adding too much, but my day two hair was sometimes a little gummy.
