What is an important consideration when selecting a hair dye?

When selecting a hair dye, one of the most important considerations is the permanence of the dye. This factor significantly impacts the overall outcome and maintenance of the hair color. Permanent dyes contain ammonia and developers that penetrate the hair shaft, providing long-lasting results, which is ideal for clients looking to make a substantial color change.

On the other hand, semi-permanent and temporary dyes have less staying power and wash out over time, making them suitable for clients who want a more subtle change or are experimenting with color. Understanding the permanence helps in managing client expectations about how long the color will last, the fading process, and the necessary upkeep or maintenance required.

This information is crucial for creating an effective hair coloring plan that aligns with the client's lifestyle and desired outcome.
