The numbers in hair colorings typically refer to the level of darkness or lightness of the color. The lower the number, the darker the color, while higher numbers indicate lighter shades. For example, a level 1 would be black, while a level 10 would be a very light blonde. Understanding the numbering system can help individuals choose the right shade of hair color to achieve their desired look. **

Hair dyes and colorings do not have a specific expiration date, but they do have a shelf life. Over time, the chemicals in the dye can degrade, leading to a less effective or inconsistent color result. It is generally recommended to use hair dye within 1-2 years of purchase for best results. Storing hair dye in a cool, dry place can help prolong its shelf life. Always check the manufacturer's recommendations for specific products. **
