Yes, there are quite a few. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Ranma x Shampoo x Ukyo' and you'll find a variety of stories with different plotlines and interpretations of their relationships.
One common theme is the chaos that comes with Ranma's gender - changing. The reader often has to deal with this unique aspect of Ranma's life. Another theme is the building of a relationship between the reader and Ranma, which can range from friendship to romance.
One great Ranma x Reader fanfiction is 'Ranma's Unlikely Encounter'. It has a really interesting plot where the reader character gets thrown into the chaotic world of Ranma and his gender - changing antics. The way the author writes the interactions between the reader and Ranma is both humorous and heartwarming.
Perhaps a fanfic where Trans Female Ranma uses her unique position to bridge the gap between the male - dominated martial arts world and the female characters. She could start a new style of martial arts that combines the strength and techniques of both genders, and in the process, she becomes a symbol of change and acceptance in the Ranma world.
Well, medicated shampoos with ingredients like benzoyl peroxide or ivermectin are often recommended for demodex mange. These can target the mites and reduce the symptoms. But it's best to consult a veterinarian for the most suitable choice.
I recommend using medicated shampoos specifically formulated for mange. Brands like Vet's Best and Malaseb are often effective. They contain ingredients that target the mites causing mange.
Biohex shampoo might work on mange, but its efficacy can vary depending on the severity of the infestation and the individual's skin condition. Sometimes, additional treatments might be needed for a complete cure.
