my Topic & Thesis Statement is this...

Topic: How Do You Know If Your Nail Salon is Clean and Safe?

Thesis: The best solution as to not getting a toe or nail fungus, is to avoid unclean nail salons.

But my teacher says "how do you persuade people that nail fungus is a real problem?

So my Question is how can i rewrite my Thesis Statement so that it sounds more like it can persuade you.

Thank you.

Your "thesis" statement is simply stating a fact; therefore, it's not really a thesis statement. You need to add your position on the topic in order to make it a thesis.

To persuade people that nail fungus is a real problem, you can approach your thesis statement by focusing on the consequences and risks associated with unclean nail salons. Here's a revised thesis statement that aims to persuade:

Thesis: Recognizing the serious health risks and consequences of nail fungus, it is crucial to choose nail salons that prioritize cleanliness and safety measures.

In this revised thesis statement, the emphasis is on the importance of recognizing the potential dangers of nail fungus and the need to prioritize cleanliness and safety in nail salons. By framing the thesis to highlight the negative consequences and the significance of clean and safe nail salons, you can effectively persuade your audience to take the issue seriously.
