This shampoo was invented by Gilderoy Lockhart, and used the egg yolks of the Occamy as a primary ingredient. The treatment guaranteed "locks of lustrous luminosity", presumably in the words of Lockhart himself. Despite most of his achievements being falsified or stolen from other wizards, this shampoo was as effective as Lockhart claimed it to be, though the expense and danger of producing it ensured it never was produced for a mass market.
