Hello, I captured head lice about 2 1/2 weeks ago, but I was treated by professionals and it was soon resolved. However, I have been very paranoid to catch lice again so I have been showering on an occasion (about 2 times a day). I shower for about 20 min and shampoo my hair about twice during my shower. Lately I have noticed that my hair has been rather itchy and I have also noticed a great number of white flakes throughout my hair. I m not quite sure if my scalp is irritated or its simply dry skin and that s why I have been itching lately. I am just deeply paranoid to catch live again. Please help
