First, the user wants an original article for the keyword "Professional Hair Colour At Home". I need to use the provided context when useful. The context seems to be a set of instructions or guidelines, but it's not explicitly about hair colour. I'll need to infer that the context is about writing style and requirements. The requirements are: - 600 to 900 words. - Natural headings. - Avoid unsupported claims. - Do not mention that this was AI-generated. I must write only safe HTML using h2, h3, p, ul, ol, li, strong, and em tags. No markdown fences. The keyword is "Professional Hair Colour At Home", so the article should focus on achieving professional-quality hair colouring in a home setting. Let me outline the article: 1. Introduction: Discuss the trend of at-home hair colouring and the desire for professional results. 2. Benefits of At-Home Hair Colour: Cost-effective, convenience, control over the process. 3. Key Factors for Professional Results: - Choosing the right shade. - Understanding hair type and condition. - Using quality products. - Following correct techniques. 4. Step-by-Step Guide: - Preparation: Patch test, gather tools, protect surfaces. - Application: Sectioning hair, applying dye evenly. - Processing: Following timing guidelines. - Aftercare: Using colour-safe products, minimizing wash frequency. 5. Common Mistakes to Avoid: - Not doing a strand test. - Over-processing. - Using dirty tools. 6. Conclusion: Emphasize that with proper knowledge and care, professional results are achievable at home. I need to ensure the article is 600-900 words. I'll expand each section with practical advice. Avoid unsupported claims. So, I'll stick to general knowledge and established practices. For example, don't claim that home dye is as good as salon dye without evidence, but I can say that with quality products and technique, results can be close. Natural headings: Use headings like "Why Choose At-Home Hair Colour?" or "Steps for Salon-Quality Results at Home". HTML structure: Use h2 for main headings, h3 for subheadings, p for paragraphs, ul and ol for lists, li for list items, strong for emphasis, em for italics. Let me start writing. First, the title: "Professional Hair Colour At Home: Achieving Salon-Quality Results Without the Salon" But since the keyword is "Professional Hair Colour At Home", I should include it naturally in the article. I'll begin with an introduction paragraph. **Introduction:** Many people dream of having vibrant, salon-fresh hair colour without the accompanying time and expense.
