It seems that the given Twitter post does not relate to a maintenance report feedback for a public flat house. The post mentions hair color, style, and brands, but there is no mention of any maintenance or infrastructure-related issues. Therefore, the answer is a JSON object with "relatedness" set to False, "type" set to "none", and "explanation" set to a short explanation of why the post is not related to the requested topic.
