We use Fairy Tales hair care products (www.fairytaleshaircare.com). We use the line - shampoo, conditioner, leave-in spray on a daily basis. We also use their lice products when applicable. AND they have monthly coupon codes for discounted stuff or free shipping!
We struggled with daycare lice on and off for three years. and then found this. Since my son started school three years ago, we have used Fairy Tales and have not had a single episode of it - even when every other child in his class got it.
Word of warning: Rid and like products are neurotoxins, which is why they worked. But alot of lice are immune which is why you hear of ppl using them three, four, five times before going to something else. But it infiltrates the host's head just as much as the lice.... My sister dealt with a bout of lice at 12 that she got at summer camp. My mother didn't quit using the chemicals until permanent brain damaged developed and my sister is now on daily epilepsy medication to prevent seizures as a result of the nuerotoxins. PLEASE don't use these on your children!
As a last resort (and this has worked for us also), shave everybody's head and keep them bald for at least a month. In addition to the bagging and washing and vaccuuming, etc.
Lice is a nightmare. I hadn't heard of that Solumel...I'll have to investigate that myself.
