I bought this to mix with shampoo and conditioner as we'd had a lice outbreak and they kept coming back. I read that tea tree oil shampoo would help prevent re-infestation. The price here was the best I found by far (including their very low shipping). The shampoo and conditioner I put the oil in smell great and seem to be working so far as we haven't had any more lice.
