The purpose of some embodiments of the invention is to delay the need for women to dye their hair in full. At least one pigment particle (about 0.0770 ml or about 1/64th of a teaspoon) may be added to a bottle of 71 ml of permanent hair dye, which allows the permanent hair dye composition to become visible and allows for more accuracy during application. Using small quantities of 5 cc per application (hair dye: 2.5 ml; developer: 2.5 ml) reduces the amount of dye applied to needless areas of the hair. The use of a make-up sponge stick allows for better accuracy. The composition is multi-use, and provides for 28 applications (71 ml bottle of dye and 71 ml of developer), and will save users time and money. All these characteristics provide for a hair dye composition that significantly reduces the amount of harmful chemicals applied to users' hair."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hair-coloring kit and method","description":"Hair dye composition and method of dyeing hair that targets only at least one grey part using a permanent hair dye component comprising a specific volume percentage of a particulate pigment to permane","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11534379","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
