This is the "companion" condition to the shampoo in the TheraNeem line. While I love the shampoo and what it does for my dandruff/seborrheic dermatitis, I can't say this conditioner is anything special. It does contain neem, the plant deriviative that calms down my dandruff so that my scalp is not flaky, but I don't know that using another condition would diminsh the wonderful results of the shampoo.
This conditioner does leave my hair soft and allow me to comb it (as opposed to how my hair is without a conditioner). However, it doesn't do anything special. It's not too heavy in that it doesn't weigh your hair down, but it doesn't give it any special bounce or body, either. You really can't expect too much from a conditioner that doesn't contain silicones, though.
In summary, not horrible, but nothing special, either.
