This is a scam of a business. Not knowledgeable and should not be in a business treating our young ones. I expected much more in terms of knowledge and professionalism but anyone can search online and open a scam business like this.
Save your money and treat your family yourself, there’s tons of great information about treating lice online. If self treatment is too daunting of a task, please at least see another reputable business. After doing some research, the owner has a past in the adult film industry. This is not a good environment to have children around.
