How do you patent or trademark a hair product?

To patent a hair product, you must first determine if your product is novel, non-obvious, and useful. Then, prepare a detailed patent application describing the invention, including claims about its unique features, and submit it to the U.S. Patent and Trademark Office (USPTO) or relevant authority in your country. For trademarking, you need to choose a unique name or logo associated with your product, conduct a trademark search to ensure it's not already in use, and then file a trademark application with the USPTO. Both processes may require legal assistance to navigate effectively.
