Many thanks to Karen. She was most helpful in helping us deal with the lice infection that both my kids received from sleep-away camp. Not only was she open on a Sunday, she provide us with in-depth instructions on applying the shampoo without any charge. Then she opened on Labor Day to do the comb out on my daughter\’s long hair. It took 2.5 hours and was worth every penny of their fee!. I will totally recommend them to anyone that has a lice infection.
